How To Reduce Heat In Grow Tent

9 Methods To Lower Temperature In Your Grow Tent (2022)

Maintaining an appropriate growth environment in your grow area is one of the most difficult aspects of growing cannabis indoors, and it may be quite difficult. It’s also the most critical factor to consider. It’s no surprise that I receive a large number of inquiries from farmers seeking assistance in decreasing their grow tent temperatures. If you want to reduce the temperature of your grow tent, there are numerous practical methods you may do. For example, moving your grow tent to a cooler part of your home, switching from an HPS to an LED grow light, and ensuring that your grow tent fan is pushing air out the window rather than into the room where your tent is placed are all good ideas.

Just to be clear, the best temperature range for growing cannabis is between 70 and 80 degrees Fahrenheit, or 21 and 27 degrees Celsius.

It is critical to maintain consistent temperatures in your grow tent in order to minimize plant stress.

To begin, I’ll discuss the most practical techniques of decreasing grow tent temperature, and then I’ll discuss the less practical ones:

Method 1: Relocate Your Grow Tent

Consider relocating your grow tent to the most comfortable part of your home. For example, if you have central air conditioning, you might want to consider your basement or a location near some air vents. You should also think about putting it near windows that are open. Your grow tent will be able to take advantage of cooler seasonal conditions if it is located near open windows. It will also make it much easier for you to run your ducting from inside the tent directly out the window.

Method 2: Route Grow Tent Ducting Out The Window:

The objective of the inline fan should not be defeated by merely blowing the air from your grow tent into the room where your grow tent is placed; otherwise, the fan will be ineffective. In order to counteract the negative pressure caused by your grow tent’s inline fan, you must draw air from the room where you have set up your tent and draw it back into it through your grow tent’s inline fan. You should take your ducting, or purchase extra ducting if required, and direct it out a nearby window to exhaust the heat.

Method 3: Turn on Your Air Conditioner:

Maintain a cool environment in the room where your grow tent is positioned. The most straightforward method of accomplishing this is to open a window during the colder months or to get a portable air conditioner to keep the area cool. Consider putting the portable air conditioner inside the grow tent if that isn’t enough to alleviate the problem. When the inline fan blows out hot air and generates negative air pressure in your grow tent, the air in this chamber is drawn back into your tent, causing the air to be drawn back into your tent.

Keep in mind that if the temperature inside your tent is 85 degrees Fahrenheit and the temperature of the external air being drawn into the tent is only 80 degrees Fahrenheit, the temperature differential will not be sufficient to cool the tent down.

The temperature of the replacement air must be in the low 70s in order to raise the tent temperature from 85 degrees to the mid-upper 70s.

Method 4: Add CO2 to Your Grow Tent

The addition of this simple-to-use CO2 bag to your grow tent will not really reduce the temperature, but it will have the same effect. Cannabis plants are able to survive temperatures that are far higher than normal when exposed to excessive CO2 levels. How much additional heat can cannabis endure when the CO2 level is elevated? A temperature range of 85 to 86 degrees Fahrenheit would be ideal for growing plants. This is in comparison to an usual temperature range of 70 to 80 degrees Fahrenheit in the absence of CO2.

Method 5: Make an Ice Box (with ice or dry ice):

This strategy will need a little ingenuity, but it is effective if you are willing to put out the effort. Because dry ice does not require replacement as frequently as wet ice, it will require far less maintenance. Using dry ice to reduce the temperature of a grow tent has the added benefit of creating CO2, which helps plants to survive at greater temperatures than normal (85 to 90 degrees Fahrenheit) as a result! What you’ll need is the following:

• Cold storage chest
• Ice or Dry Ice
• Oscillating fan
• Refrigerator

How to assemble: This may be as simple as putting your ice in a container or chest and directing an oscillating fan at it to cool it down. To be more imaginative, you may opt to seal the chest and cut a hole on either side of it, placing a fan in one hole and allowing air to escape through the other. A word about dry ice and carbon dioxide: CO2 is present at a concentration of 400 parts per million (ppm) in fresh air. Most gardeners agree that a CO2 concentration of 1,200 to 2,000 parts per million (ppm) is optimal for considerably improved plant yields.

• Concentrations more than 2,000 parts per million (ppm) can be harmful.
• Due to the fact that CO2 is heavier than air, you should have an oscillating fan operating to circulate the gas around the camp.
• When Using Regular Ice:If you don’t want to use dry ice, you might try making salt-ice instead.
• The use of salt allows the ice to remain frozen for a longer period of time.

Method 6: Make Sure Your Inline Fan is Strong Enough:

The inline fan in your grow tent is an excellent initial step in the process of eliminating heat from the tent. By clicking here, you can read my post on how to choose the proper size fan for your grow tent. Generally speaking, your inline fan should be replenishing the air in your grow tent once per minute, according to the rule of thumb.

You must also consider the lower fan power caused by bends in the ducting as well as the use of a carbon filter when designing your system. You might want to consider increasing the speed of your inline fan or purchasing a more powerful one if your current one isn’t powerful enough.

Method 7: Switch from HPS / HID Grow Lights to LED Grow Lights:

HPS and CMH grow lights generate a lot of heat. Consider upgrading to LED grow lights, which operate at a lower temperature and make maintaining the temperature of your grow tent easier. My time has been spent studying and updating a current list of the finest LED grow lights available, so please have a look at it if you are considering making the move to LEDs.

Method 8: Place Your Grow Light Drivers Outside Your Grow Tent:

The Mars Hydro TS-3000 (4×4 ft) and the TSL-2000 (2×4 ft) versions of LED grow lights, for example, feature replaceable drivers if you decide to make the conversion from HPS to LED grow lights. This is a significant advantage for growers that have difficulty decreasing the temperature of their grow tents.

Method 9: Relocate Hydroponic Equipment Outside Your Grow Tent:

If you’re growing hydroponically, you may be employing pumps, filters, reservoir chillers, or other electrical equipment that may be moved with the use of an extension cable or expanded pipes to accommodate your growth needs. Consider relocating as much of it as possible outside to help lower the warmth inside the grow tent. As you can see, there is no one perfect way for decreasing the temperature of a grow tent. There are several options. You may find one way to be more convenient or effective than another for you.

• The dry ice approach is my personal favourite if the simpler ways don’t work for you.
• While it may not be the simplest approach to use, I believe it is one of the most successful when it comes to raising the temperature of your grow tent environment to a comfortable range.
• Learn how to determine the coverage of grow lights.

To cut a long tale short, you can take immediate action to alleviate the issue.

• In order to keep the grow room cool
• Make a decision that will prevent excessive temperatures from causing damage to your plant’s health.

For both procedures, you must be aware of the number of possible approaches as well as the specifics of how they operate.

The subject of today’s discussion will be concluded with this statement: Please continue reading.

High Temperates Kills the Plant. Here is How-

What precisely occurs when the temperature in your growing room is too high? Answer: Temperatures have an effect on a plant’s capacity to photosynthesise, seed germination, and fruit/flower growth. Here’s why: Which, when taken as a whole, leaves you with less and lower-quality produce. To simplify things, here are some fundamentals concerning high temperatures in growth environments: First and foremost, grow lights function as warmers. LED, high-pressure sodium lamp, fluorescent lamp, plasma lamp, and every other type of light generating heater we can think of are all light emitting heaters.

• The leaves and roots of plants are immediately affected by the high temperatures seen in grow rooms.
• The heat from the leaves is removed through the evaporation of water via the Stomata, which in turn cools the plants.
• While water is moving through the Stomata, the guard cells around it are activated by the high temperatures and conditions.
• As a result, your plants will eventually cease to function due to a lack of photosynthesis.

How to Detect ‘Too High’ Temperature of Your Grow Space?

A great grow environment should maintain a constant temperature between 70 and 80 degrees Fahrenheit (21 and 26 degrees Celsius). This is what I mean by ‘uniform,’ which means that it should be the same across the contour. When the temperature surrounding the sources (lights) is greater, oscillating fans can be used to circulate the air. That is, however, the usual temperature range for fast-growing annuals in general. A slight increase in temperature may be beneficial as well, as long as you have something to protect the root zone, such as a water chiller.

• Plants either cease to grow or become tall and leggy
• The flower is not forming correctly
• Essential oils are becoming depleted. Fruits that rot before their time

However, it is usually preferable to notice a problem with the temperature and surroundings of your plants before allowing them to wilt. A 3-in-1 moisture, light, and pH meter may be a useful addition to any kit. Here’s one of the most popular from Healthy Wiser. So to be clear, anything above 85°F or 90°Fhigh will be considered, and we will search for a solution throughout the remainder of this piece.

8 Actionable Grow Room Cooling Solutions

We have arrived to the center of the post, which is exactly what you are looking for right now. Here is a list of 7 quick and simple treatments for high grow room temperatures that are both simple and effective:

1 of 7: Boost Up the Air Exchange Rate

In an indoor growing environment, hot air builds quickly. It is possible that you have installed an input and extractor fan in order to remove the heated air. Increase the speed of this fan duet to increase the rate of air exchange in the room. You can manually change the fan speed every now and again, but there are programs available that can do it automatically and with pinpoint accuracy. My favorite is the recently released Titan Controls Kronus 4, which is my personal fave.

To get a better and cooler air exchange, one more effective advice is to gather the intake air from the coolest spot that is readily accessible close by. I’ve seen farmers use an air conditioner to chill the water they’re using as an input.

2 of 7: Have A Low-Strength Nutrient Solution

When the temperature is high, more water is absorbed by the leaves, resulting in a greater demand for water by the root system. As a result, they are compelled to consume additional nutrients. Furthermore, increased nutrient consumption is associated with an increased risk of plant toxicity concerns. This finally leads to their demise, though. In order to prevent this from happening, dilute the nutrient solution by a specific proportion (20 percent in most cases). All that is required is the addition of the determined amount of fresh water.

An air pump and some air stones should be included in the solution.

3 of 7: Enhance Air Flow

The medium via which heat is transferred from heat sources to plants is called air. It follows that improving air circulation throughout the tent’s inside will have a positive impact on reducing its heat-producing effects. Using an oscillating fan is the most efficient method of doing this task. Place it in such a manner that it can circulate air in nearly every area of the room, particularly the air between the heat source and the plant canopy. I’d like to share with you two of my own recommendations: –

• The VIVOSUN 6′′ Clip-On Fan is the best oscillating fan for grow tents. Hurricane 18″ Wall Mount Fan is the best oscillating fan for a grow room.

4 of 7: Enhance Humidity

Humidity is the most apparent factor to consider when discussing temperature, and it comes in second place. In the same way, vice versa. They have an effect on one another, and you can cope with the increased temperature in a grow area by adjusting the relative humidity in the space. Now, how can you keep your grow tent cool by regulating the humidity in it? If the temperature rises in a curved space, relative humidity drops, according to the findings of a study published on Sciencing. Even if the temperature in your grow room is extremely high, you should be concerned if the relative humidity is also unusually low.

Now, here’s a fun fact: increasing the humidity level will not only prevent the plants from drying out, but it will also cause the plants to chill down.

In addition to increased humidity, there is a fall in temperature, which works to your advantage.

5 of 7: Switch Off or Dim A Few Light Sources

Many of us growers believe that putting the light sources above the plants’ heads will alleviate the temperature issues we’re seeing. However, the reality is that while this may reduce direct heat on the plants by a little amount, it will not reduce the temperature of the overall grow tent. What actually works in practice is to turn off 50% of your light sources for a period of time. If you have two, you may switch one of them off for a short period of time and it will not cause any problems.

It works well with high-pressure sodium lights. It is important to understand how to choose the proper wattage of lights for your indoor plants in order to avoid any heat concerns that may arise from the light sources.

6 of 7: Chill The Nutrients

If you believe that your plants can endure a high temperature under any circumstances, you are mistaken. Almost each grow room plant can endure temperatures between 90 and 100 degrees Fahrenheit, and even greater temperatures. If you live in a hot climate and are unable to find a rapid way to manage the temperature, but still want to maximize your yield, you should chill the nutrients to a temperature between 55 and 65 degrees Fahrenheit. It is necessary to employ a pump that circulates the nutrient solution in order to prevent the temperature of the nutrients from rising again.

7 of 7: Using Air Cooled Hoods

The heat released by light sources and other forms of illumination is the most significant contributor to the increasing temperature in your grow room. So, why don’t you use a reflective hood that is air-cooled? It’s something that can remove up to 50-60 percent of the heat created by grow lights, depending on how efficient it is. There are versions, like as the Magnum XXXL, that do an excellent job of dissipating the heat generated by the light source. They are completely sealed and can be used in conjunction with duct fittings.

3 Bonus Tips

I’m confident that implementing a few of the aforementioned suggestions will assist to reduce the excessive temperature or, at the at least, let your plants live in a hot environment. Here are some additional extras to go along with these suggestions.

Run the lights at night

• Despite the fact that we are all aware of this, I stress on it more since it will help to keep the ambient temperature low.

Seal the entire space up

• If you are a grower who lives in a hot environment, this may be even more beneficial to you. Such a grower is more likely to use an air conditioner as well as a carbon dioxide generator to keep the environment cool. It is preferable to utilize a subterranean space since it acts as a natural thermal insulation. Aside: Plants in a grow room can withstand high temperatures and high carbon dioxide levels in the air.

Toughen up Cell Walls of the Plants

1. This will aid in the greater survival of plants, as well as the colonization of the root zones of plants, in the long run. A high-quality Silica Supplement for plants is essential in this process of toughening. Currently, I’m finding this one from Botanicare to be really beneficial

How To Cool A Grow Tent Without Wasting Tons Of Money

When it comes to growing cannabis indoors, heat is the one issue that almost every grower has to deal with. Growing marijuana in a small space, along with the heat created by grow lights and other equipment during the summer months, causes temperatures to rise much over what is considered safe for marijuana plants. If you want your plants to survive until harvest time, you must take action to combat the heat. Fortunately, there is a great deal you can do. For decades, growers have been able to successfully deal with heat-related issues.

Continue reading to find the most effective methods for keeping your grow tent cool, even during the warmest summer days.

How To Cool A Grow Tent

Based on your location, the temperature in which you reside, the sort of grow lights you are using, and a variety of other circumstances, you may have a significant heat problem or a very minor one. All of the ways for cooling your grow tent that are discussed here can make a significant impact in the temperature inside. However, most of them will not be sufficient on their own, unless you are dealing with a very little quantity of extra heat. If you’re dealing with a more complicated topic, you’ll need to mix numerous approaches.

More information may be found in “Do Grow Tents Prevent a Helicopter From Detecting Heat?”. Having said that, even if you do not have a significant heat problem, combining numerous solutions is always going to be the most successful, and this is precisely what we advise you to do.

Switch To LED Grow Lights

If you’re still using high-pressure sodium or high-pressure mercury vapor grow lights, it’s time to make the transition to LED. Or, at the absolute least, to the Children’s Miracle Hospital. Do not even consider using HPS or MH if you are just starting out in the business world. LED grow lights (and CMH grow lights as well) are simply superior than older HPS or MH grow lights in every aspect (except initial cost, though even that is fairly close these days). LED lights consume less electricity to produce the same amount of light, and they generate less heat.

Furthermore, you will not be need to update bulbs every two to three years.

If you want to save time and money, opt for the HLG grow lights, which are manufactured in the United States.

Spider Farmer is unquestionably the greatest, but if your budget is even more restricted, theViparspectra Pro Series lights are a good alternative.

Put Ballasts Or Drivers Outside The Grow Tent

If you are using high-intensity discharge (HID) lights and want to use them indefinitely, you may limit their heat output within the grow tent by placing their ballasts outside the tent. Because the ballasts generate a significant amount of heat on their own, placing them outside can be beneficial. You may also dim the ballast in order to lower the output of the lights as well as the heat produced by the ballast in itself. Even with LED grow lights, this might be a viable solution in some situations.

The Quantum fixtures and the Spyder type fixtures are both capable of doing so.

If you have an LED grow light with an external driver, you should be able to remove it from the fixture and set it outside the grow tent without difficulty.

Cycle Air In And Out Of The Tent

At the absolute least, you’ll want an exhaust fan and some ducting in order to do this. In addition, a charcoal filter will almost certainly be required. Furthermore, if you are utilizing a large grow tent, you will want an intake fan as well as a ventilation fan. Read our post on how to determine the size of fan you require. In order for my grow tent to function properly, I need to know what size fan I’ll need. Make use of the exhaust fan to remove the air from the grow tent. You could just vent it into the room, but it would cause the room to heat up, and you’d end up with an issue that was identical to the previous one.

1. However, even in this case, it is preferable to use the ductwork to direct the air out a window or into the attic.
2. A simple system for producing marijuana indoors.
3. You should probably use a carbon filter to eliminate the stench from this air before releasing it into the surrounding environment to avoid spreading it further.
4. Although you may place this carbon filter outside of the grow tent to save room, it is normally preferable to do so if at all feasible within the tent.
5. Because cold air tends to settle towards the bottom of the tent, the intake should be located near the bottom of the tent.
6. In order to draw fresh air into a larger grow tent, the exhaust fan will need to be very powerful, which means you’ll need an intake fan that can keep up with the exhaust fan in order to draw fresh air into the tent.
7. Maintain a comfortable temperature in the room outside the tent.
8. It is also possible to install an air conditioner directly in the tent (see below).
9. The following are some considerations to keep in mind when doing ducting.
10. Utilize light-proof ducting and make a u-shaped bend at some point in order to ensure that no light enters through the aperture at the end of the duct.

Pests can also enter through the ducting or the intake vent, in addition to being drawn in by the light. Consider installing a screen over each entrance to keep them out completely.

Run An Oscillating Fan In The Grow Tent

The grow tent should always be equipped with at least one oscillating fan, regardless of whether or not you are ventilation your grow room. In large tents, you’ll need a number of these. Find out which fans are the most effective for grow tents in this article. These fans keep the air flowing over the plants at a constant rate. Not only does this assist to keep things cold, but it also helps to prevent the growth of mold. This is especially crucial during the early phases of the grow when you want to increase the humidity levels in the grow tent, as well as during the latter stages when huge buds and fan leaves obstruct air movement in the grow tent.

Put A Swamp Cooler In The Tent

Swamp coolers chill the air by evaporating the water contained within them. For this reason, they are often referred to as evaporative coolers. They are more efficient at chilling air than other types of coolers (such as regular air conditioners), but they also add moisture to the air they are used to cool. If you need to boost humidity, a swamp cooler is a fantastic tool. However, if your grow environment is already too humid (or just perfect), you should avoid using a swamp cooler. Instead, use a conventional air conditioner to cool down.

Put An Air Conditioner In The Tent

This is the quickest method of bringing the temperature of the air within your grow tent down. However, it is only something you would want in a larger tent because it takes up a lot of room and significantly cools the air. It also helps to reduce the humidity in the grow tent. An air conditioner in a room outside the tent will usually be sufficient in most situations. As a result, it helps to chill the air outside the tent, which is then drawn inside the tent via the intake.

Run Lights At Night

If you are growing indoors, there is no rule that says your plants must have the same daytime hours as you do throughout the growth season. Their sunlight might be our nighttime, and vice versa. Temperatures are colder at night, which will assist to counteract the heat generated by the lights during the day. Additionally, there may be an extra benefit. Some electrical companies offer cheaper electricity prices throughout the evening and midnight hours, which means you may save a little money as well.

Plants that bloom, such as marijuana, require 12 hours of continuous darkness every single day to thrive.

Move The Grow To The Basement

Heat increases, as we have already established. As a result, the lower levels of your home will be significantly colder than the top levels. If your grow tent is presently placed upstairs or elsewhere, relocating it to the basement will result in a somewhat cooler ambient temperature, which will make it simpler to keep your tent cool while it is being used.

Cooling A Grow Tent: Final Thoughts

Maintaining a cool growing environment in order to enhance development and output is likely the most difficult challenge marijuana farmers must overcome. There are a plethora of things you can do, to be sure, but they all need time, effort, and money. It’s simply a matter of viewing it as a necessary component of indoor growing operations.

Accept the fact that you will need to acquire fans, ducting, filters, and possibly even air conditioning units in order to complete your project. Additionally, you should consider using LED grow lights rather than obsolete HPS or MH lights (we still recommend CMH, though we prefer a quality LED).

How to Reduce Heat Inside a Grow Tent

When you are first starting out in a new location, it can be challenging to maintain the optimal temperature for your cannabis plants. Because of the restricted airflow within a grow tent, it might be even more difficult to regulate the temperature inside. It can be difficult to keep the heat levels under control, which is why we’ve put up this guide to assist you with the procedure.

Are High Temperatures Bad for Cannabis Plants?

The ambient temperature may be significantly higher than the 70 degrees Fahrenheit that your plants find pleasant if you are growing marijuana in a hot location or in an area where heat cannot disperse, causing heat stress in your plants. An increase in temperature can cause your cannabis plants to grow more slowly, produce less, and possibly die if the temperature continues to rise. Heat is a major worry throughout the flowering phase of cannabis plants, as well as for those who grow cannabis hydroponically, when the roots are exposed to the elements (as opposed to being protected by a pot and layer of dirt).

Examine the following easy methods to begin lowering the heat temperatures inside your growing space right away.

Using Oscillating Fans Inside Grow Tents

While fans will not completely reduce the heat within your grow tent, they will assist you in better circulating the air inside. Keeping your plants as near to the sun as possible, where the majority of the heat is created, is essential in the conventional growing environment. To dissipate the heat generated by your lights and to keep your plants cool, consider using an oscillating fan.

Ceiling or Floor Vent for Grow Tent Exhaust?

Because of the way heat rises, deciding whether or not to put your exhaust fan in the ceiling vent of your grow tent can make a significant impact in your growing results. The ceiling vent will allow hot air to be pulled out while passively drawing air from the floor vent, which will be cooler because it is higher in the room. This simple setup tweak may make a significant difference in the amount of work necessary to keep the temperature inside your tent under reasonable control.

Use a Cooling Humidifier

The use of a humidifier with a cooling effect, such as Vick’s Cool Mist Ultrasonic, inside your grow tent will assist to lower temperatures even further while simultaneously raising humidity to acceptable levels, as shown in the chart below. However, you will want to be cautious not to let the humidity to rise too much, since this might unintentionally raise temperatures. While a humidity level of roughly 40% is regarded best for vegetative marijuana plants, greater humidity levels are preferred for seedlings, which benefit from lower humidity levels.

Use Buckets of Water, or Ice

When used in conjunction with a humidifier that has a cooling effect, such as Vick’s Cool Mist Ultrasonic, the temperature of your grow tent will be reduced even further, while the humidity will be increased to acceptable levels. Although you should avoid allowing the humidity to rise too much, this might have the unintended consequence of raising the temperature.

Humidity levels of roughly 40% are regarded best for marijuana plants in their vegetative stage; however, even greater humidity levels are beneficial for seedlings.

Control the Temperature Outside of the Grow Tent

The temperature inside your grow tent will naturally be a few degrees warmer than the outside temperature due to the nature of the material. As a result, you should always strive to increase airflow in the surrounding regions, ensuring that all of the heat created by your grow tent is dissipated. As a result, it is preferable to connect your exhaust fan directly to an exterior window, as this will prevent any heat buildup from occuring near the growing region. It may also be necessary to employ additional oscillating fans or air conditioning to keep temperatures outside of the grow tent within acceptable ranges.

Optimize your Marijuana’s Day and Night Cycle

The majority of farmers will also opt to operate their lights for the whole 24 hour period, rather than the traditional 16 hours of light followed by 8 hours of darkness. Running your light for a full 24 hours will result in a 30 percent increase in the amount of electricity used as well as the total quantity of heat emitted by the light. While this may not be a major worry for many growers, it is vital to be aware of the declining returns that are connected with this situation. In other words, your plants will not develop 30 percent more quickly than they would if they were just exposed to 18 hours of light.

It is common for temperatures to be at their greatest during the daytime hours.

The additional benefit of using this strategy is that your energy bills will be lower as a result of the lower cost of electricity during non-peak periods.

Supplements to Protect Against Heat Stress

It may surprise you to learn that a variety of supplements are quite helpful in mitigating the negative effects of high temperatures on your plants by assisting them in dealing with heat stress. Supplements such as these should only be used as a last option in order to minimize the amount of moving components in your garden and to avoid creating unnecessary complexity. But if you have tried all of the procedures above and are still experiencing high temperatures inside your grow tent, these supplements may be just what you need to keep your plants from suffering more harm from the high temps.

Silica for Cannabis Plants (Potassium Silicate)

Silica supplementation is beneficial for a variety of environmental conditions that your plants will want to avoid, and it may assist your plants in dealing with the stress associated with higher temperatures. Because of the enhanced resistance to stress, your garden will be able to thrive at temperatures that are above normal without suffering any harmful consequences. Supplementing your cannabis plants with silica has a variety of other indirect benefits, such as a mild corrosion to the leaves, which makes it less appealing to pests and other insects (if you were growing outdoors).

In order to understand more about the various benefits silica may give to your garden, we advise you to read on.

Use Supplements for Root Health

If you are growing cannabis hydroponically, the roots of your cannabis plants will be exposed, making them much more sensitive to greater temperatures than they would be otherwise. As soon as temperatures reach uncomfortably high levels, the condition of the roots begins to degrade. Visually, this will become apparent, and if you touch the roots, they will feel as though they have been covered with slime. The administration of a root health supplement may have a significant influence on the vitality of your plant’s roots, and can even help them to recover from their state of ill health.

Heat Resistant Strains

Believe it or not, certain strains of cannabis are really more heat tolerant than others and can withstand greater temperatures than others. Typically, Sativa-dominant strains are preferred by high-temperature growers, and this gene may be found in many famous marijuana breeds. Choosing one of these strains should be regarded a last resort for those who have been unable to maintain temperature control within their grow tent.

How to Minimize Heat in a Grow Tent

In order to keep consistent temperatures in a grow tent, there is a science behind it. If you’re having trouble with overheating or shifting temps, you’re not the only grower who’s had to deal with this problem before. You surely won’t be the last one to do so. Temperatures between 70 and 80 degrees Fahrenheit are generally considered to be the ideal range for your plants. This is the range in which your plants can absorb the optimal quantity of nutrients—not too much, nor too little—without being stressed.

1. To make matters even more complicated, merely reducing the amount of heat generated in a grow tent is not enough.
2. Temperature fluctuations stress your plants, and they will suffer as a result.
3. Achieving either of these goals is difficult, especially for first-time gardeners.
4. The unfortunate news is that this is the case.

Choose LED Grow Lights

The climate within your grow tent is greatly influenced by the type of grow light you choose to use. The majority of growers use either high-intensity discharge (HID) bulbs or LED lights. HID bulbs are available in two varieties: HPS (high-pressure sodium) and MH (metal halide). High-intensity discharge (HID) growers often utilize MH for the vegetative phase and HPS for flowering. This has been the conventional method of growing tent lights for many years. However, it is no longer the recommended alternative.

Even while LED technology is still in its infancy and requires a somewhat greater initial investment, the advantages it offers are numerous.

In addition, they produce substantially less heat.

It is true that you will have to deal with heat in a grow tent regardless of the sort of light you use for your plants. LED grow lights, on the other hand, make the job considerably simpler. When you utilize LEDs, you will require far less additional cooling.

Install a Quality Ventilation System

If you do not have a ventilation system, you should install one immediately. If you have one, be certain that it is connected to your property and that it has enough power to satisfy your requirements. A ventilation system regulates the temperature of a grow tent by releasing hot air and bringing in cooler air from outside the tent at the same time. A typical system consists of an exhaust fan, ducting, and a carbon filter, which is used to eliminate odors associated with plants. The exhaust fan, also known as an inline fan, is in charge of the exchange of air in the system.

The directional movement of the heated, stagnant air expelled by your exhaust fan is controlled by ducting.

Because you don’t want to introduce any more old air into the area around your tent.

On that topic, let me say.

Manage Heat in a Grow Tent by Managing HeatAroundthe Grow Tent

Think about where you’re going to put your grow tent. Keep in mind that your high-quality ventilation system will draw in all of the air from around your tent and distribute it throughout the grow room. If it’s hot in the room, you can bet it’ll be hot in the tent as well. Moving to a place that is naturally cooler, such as a basement, can be a good option for your situation. If you have central air conditioning, another option is to locate your grow tent next to air vents to maximize airflow.

Access to cooler air is provided while also making it simple to send your ducting out of the room with this choice.

Consider an Air Conditioning Unit

Put your grow tent somewhere else if you don’t like it. Keep in mind that your high-quality ventilation system will draw in all of the air from around your tent and distribute it throughout the grow environment. If it’s hot in the room, you can bet it’ll be hot in the tent, as well! Moving to an area that is naturally cooler, such as a basement, can be a good option for you. You may also set your grow tent near air vents if your home is equipped with central air conditioning. In addition to this, it is possible to place your grow tent near a window that is now open.

Remember: Electronic Equipment Generates Heat in a Grow Tent

Electricity is used to generate heat in a grow tent by drivers, hydroponics pumps, filtration systems, and any other electrical equipment that is used to produce high yields. Now, it’s evident that you’ll be unable to quit using these necessities.

These things may, however, be possible to be relocated outside of the tent while still remaining linked to the interior through the use of extension cables or longer pipes. You’d be surprised at how much heat you may save by just turning off a few electronic devices.

Run Your Lights at Night

If you set up your grow tent correctly, you should be able to provide your plants with a growing environment that is fully free of light pollution. This implies that you are not required to conform to the natural day and night cycle of the world. Your plants are completely oblivious to the change. Inside your grow tent, daytime is defined by the time you set for it. You’ll want to make sure that your plants have a regular 24-hour cycle going forward. You may, however, plan your lights-on period to occur during the nighttime hours.

Even if the light cannot reach your plants, its rays warm the space in which you store your tent, as you can see.

By using your grow lights throughout the night hours, you are exchanging one heat-producing cause for another, rather than doubling up on the problem.

Keep the Heat and Add CO₂

If you’re new to home growing, we urge that you follow the guidelines outlined above to keep your temperatures as low as possible. For those who have gained some expertise with their homegrown crops and are ready to move on, the following alternative could be worth considering: Instead of reducing your carbon dioxide levels, you should raise your carbon dioxide levels. When all other factors are equal, too much heat is detrimental to your plants. In the same way, too much CO2 is harmful. However, by increasing both factors at the same time, you may really enhance your yields.

You can find out all you need to know about CO2 fertilization right here.

Whichever approach you use to making the most of your heat or minimizing it, we wish you the best of luck in finding the perfect temperature for your plants.

How to Cool A Grow Tent? – 10 Actionable Ways to Take

What do you think the months of June through August are like for you? We’d say it’s scorching. And when given the opportunity, we run under the air conditioners or at the very least beneath the fans to cool ourselves off. If that’s the case with ourselves, why shouldn’t it be the same with the plants? We’re talking about an agrow tent in particular, to whom you’re pretended to be ‘Mother Nature’ from every angle possible. Consequently, if you’re concerned about how to cool a grow tent that’s becoming excessively hot, it’s quite OK to choose that route.

Listed below are five strategies for keeping the temperature of a grow tent under control. If you’re a grower, we’re willing to bet you’ll be unable to stop scrolling until the very end. Let’s get this party started-

What Turns a Grow Tent Hot?

I’m curious how you’re feeling about the months of June through August. Guess it’s going to be a scorcher! Undeterred, we run beneath air conditioners or at the very least under fans to keep cool. The same might be said for plants if this is true for us. We’re talking about an agrow tent in particular, to whom you’re trying to be ‘Mother Nature’ from every angle possible. This means that you may safely cool down a grow tent that is running particularly hot if you are concerned about doing so.

Listed here are ten strategies for keeping the temperature of a grow tent within reasonable limits.

Begin with the basics:

• If the ventilation system fails, the heat generated within the tent is trapped within the tent itself. What is the obvious ramification of this? No doubt about it, there’s heat trapped within the tent, boosting the temperature
• It’s likely that the tent’s HVAC system isn’t performing up to pace due to the excessive heat in the surrounding environment. The higher the temperature outside, the greater the amount of work the cooling system needs to do. Otherwise, the temperature and heat would soar to dangerous levels. The presence of too many heat sources within the grow tent region and not enough cooling agents to neutralize them is another probable explanation for the problem. The absence of adequate insulation around the tent’s outside is another potential source of heat loss that we would need to solve. And that is most likely to occur in summer climatic zones
• Yet,

Have you acknowledged each and every one of them? Let’s have a look at some of the various solutions for getting them sorted out for a good purpose.

Ways to Cool A Grow Tent- Without Products

During this first section of the solutions, we’ll speak about several improvised methods of cooling down a grow tent. These will not be associated with the purchase of any items or the incurring of any costs in any way. All of the action will be focused on improvisation, optimization, and correction. Let’s have a look at it-

Way 1: Get the Best Out of the Ventilation Scopes

Grow tent kits available on the market are equipped with vent holes through which you may insert carbon filters, ducting into and out of the tent, and anything else that may be necessary. On that note, you must make certain that these venting chances are utilized to their full potential. And this will eventually result in a reduction in heat accumulation and a decrease in temperature. Another challenge that may be addressed from this position is the maintenance of appropriate airflow. You may increase ventilation by following a few simple guidelines that can be implemented with any available resources you may have at your disposal.

• Reposition the clip-on or stand fans throughout the grow space to better suit their needs. Additionally, if they offer to modify the speeds, you can do so. Relocate the location of the input duct opening to the coolest suitable location in the immediate vicinity. When this is done, cold air will be drawn into the tent, resulting in a dramatic reduction in the temperature within. If they have not previously done so, they should consider adequately closing the vent openings.

Way 2: Diminish the Heat Sources as much as Possible

The most basic approach to cooling down a grow tent is to utilize goods that chill the air. However, if we believe contrary, we may achieve the same result by reducing the amount of heat that is produced within a tolerable range. And it works just as well as the first method. When it comes to naming heat sources in a grow system, there are just a handful that come to mind. Let’s have a look at the list:

• The lights (1 source of heat)
• Space heaters
• Motor-driven devices
• Soil that carries heat inside it
• And other sources of heat

Now, let’s speak about thegrow lights first, because they are the primary producers of ozone depletion in this environment.First and foremost, lights must be kept at a reasonable distance from the plants. After that, you can switch to using air-cooled light hoods instead of ordinary light hoods. As a result, these hoods are responsible for removing the hot air produced by the lights and preventing it from entering the grow room.Apart from these two points, there are a few small details that you should be aware of.

Additionally, you must employ automatic controllers to turn off the lights when they are not required.

For the other sources of heat, you may follow the same guidelines that we recommended for the lighting system. As you are well aware, it is essential to restrict the amount of heat produced to a comfortable level.

Way 3: Optimize the Ducting

This is something that many growers ignore, and as a result, they find themselves in an unexpectedly heated growing environment. In the ducting, this is the result of an excessive amount of bending. The following is a straightforward calculation: for every 90-degree turn within the duct, the fan must work 5 percent harder than it would normally be required to accomplish. This means that your fans will be less effective the more twists and turns there are in your ducting. Result? Poor air transmission and an increase in the temperature.

Moreover, this is true for both the intake and the exhaust ducting.

However, while doing so, you must make certain that the bending is maintained to a bare minimum.

Way 4: Avoid Low Humidity in the Grow Tent

It is possible that you have a definite belief that there is a direct relationship between humidity and temperature if you have done your research. Particularly when dealing with a limited space such as a grow tent, the connection becomes more clear. The general rule of thumb is that the lower the humidity, the higher the temperature will be in any given situation. In the same way, vice versa. As a result, if the humidity is below a certain level, it is possible that heat and temperature accumulation may occur within the growing environment.

Increasing the humidity levels in the grow tent if the humidity levels are lower than that will benefit both the plants and the overall temperature condition in the grow tent.

Way 5: Reposition the Grow Tent As Per the Exterior

As long as the heat difficulties are taken into consideration, the location of the grow tent within the house is quite vital to the success of the operation. Typically, growers like to store them in secluded areas such as the garage, cupboards, or other similar locations. However, in the event that you are not one of them, the following are some pointers. Place the grow tent away from the south-facing wall of your home. This will help to keep the bugs out. This is likely to prompt thoughts about how to construct a perimeter around the grow tent.

The heat of the sun is transferred to the tent through the nearby air, causing the tent to inhale hot air.

Rest confident that you will be able to take care of the ventilation on your own.

Ways to Cool A Grow Tent – With Products

It is a well-known truth that air conditioners are intended to reduce the temperature of a room. And, in a small and curved environment such as a grow tent, this is far superior than any other option available to you.

Consequently, if you want to invest money after cooling down your tent, compact ac units are the ones you should consider purchasing later. The size of your grow space, on the other hand, will determine which of the following alternatives you can use:

Even though little air conditioners are less powerful, they are capable of cooling tiny grow tents such as 4×4, 4×5, 5×6, 6×8, and even 10×10. They typically produce a respectable BTU output and are easily transportable. As a result, while it cannot be used in the tent, it may be utilized in other situations.

Way 2: Use Fans

Because you are already familiar with the construction of an agrow tent, we assume that you have already occupied the fan(s) in it. However, given that the current scenario suggests that these fans are not adequately cooling the tent, we believe there is room for innovation. Replacement of the old fans with new and more efficient ones is what we’re talking about! Finding the proper size and kind of fan is always important when it comes to maintaining a healthy temperature for your growing plants.

1. Inline fans: Fans that are built into the ductwork and are responsible for both the air intake and the air exhaust
2. Oscillating fans: These fans are either openly attached to the grow tent wall or stand on the floor to ensure that the grow tent’s interior air circulation is properly maintained.

As a result, identify the appropriate size for both of these kinds and place them in an appropriate location. Location of fans is also significant since, if they are put in the wrong location, they will just circulate old, hot air inside the air instead of fostering new and cold breezes around the room. Inline fans that we recommend are as follows: Oscillating fans that we recommend are listed below.

Way 3: Use Water Chillers

If you discover that ac units are prohibitively pricey for the amount of indoor gardening you do, there is a finer and more economical alternative available. And they are referred to as water chillers. Chillers for water are electric devices that absorb wet vapors while leaving the cold and cooled ones in their wake. There are two types of chillers: water-cooled chillers and air-cooled chillers. Water-cooled chillers are more common. Despite the fact that the latter is less expensive, it is less effective for grow tents larger than 44.

These devices are equipped with a water reservoir to keep the water contained and an evaporating mechanism to reduce the temperature of the surrounding environment.

As you have seen previously, insufficient humidity is one of the probable causes of the heating of grow tents.

Furthermore, with a water-based chiller, this possibility is well within the acceptable range. However, in the best-case situation, we recommend that you use a decent humidifier to deal with any humidity issues you may be experiencing. Water Base Chillers We Recommend are shown below.

Way 4: Control the Climate

When it comes to heat management in a grow tent, you may make considerable strides forward by regulating the environmental factors on your end. By doing so, we’re tackling issues such as-

1. Grow lights, inline fans, oscillating fans, air conditioners, humidifiers, dehumidifiers, and any other electric HVAC equipment are all recommended.

Having the ability to apply some preset regulating directives about when they should turn on and when they should remain turned off will be quite beneficial. This is particularly effective in preventing the intrusion of unnecessary heat into the home. In addition, if you maintain tight control over the grow tent environment, there are a number of health benefits for the plants as a result. The controllers are available on the market in a variety of configurations. There are controllers that work alone, and there are controllers that work in a 360-degree environment.

Way 5: Use An Ice Box

Think about it: what could be any more inexpensive than a water-based chiller? Yes, you read it correctly; the icebox is the culprit. It is, in fact, a box of ice, just as the name implies. If you don’t want to use a box, you may use a bucket and transform it into a homemade icebox. These are not things that are available for purchase at a store. However, if you’re interested, you may create one yourself by following a few easy steps.

Closing Words
