What Lights Should Be Used Ina Grow Tent

The Ideal Marijuana Grow Light Setup

If you ask 100 marijuana farmers which grow lights are the most effective, you’ll receive 100 different replies. Okay, maybe 95 percent. The point is that almost everyone has a different point of view. However, the fact is that there is no such thing as a “best grow light.” It is actually a blend of multiple light sources that produces the greatest cannabis illumination. “Ultimate Lighting” is the headline of an article from theHigh Timeswebsite (link gone, content no longer available) that explains four lighting systems for different-sized indoor gardens.

Basic Lighting Principle for Growing Weed

The concept is fairly straightforward, in fact:

  1. Display an LED or HPS light with a high output and full spectrum above the plants, and a lower power and blue spectrum light source to the side of the plants.

The overhead HPS or LED lamp provides the majority of the light required by the plants. An additional source of light is provided by a blue light source, which can be generated by an MH bulb, a cold (5500K and higher) fluorescent bulb, or an LED equivalent (bar lights like theseare excellent for this). It is located around one-third of the way down from the canopy’s highest point, in the rows between the plants, and provides supplemental lighting. The powerful light from above nourishes the plants and encourages rapid development as well as abundant bud formation.

  • Production in the lower areas of the facility suffers as a result of this situation.
  • When you use this marijuana grow light configuration, you may have the best of both worlds.
  • In addition, when just overhead illumination is used, the lower sections of the plants are often looser and less lush than those in the canopy.
  • Here are several examples of settings from the High Times article that demonstrate this approach in practice:

Marijuana Lighting for a Closet Grow

When growing weed in a small location, like as a closet, you want it to be short and bushy in appearance. This guarantees the highest possible yields without the need for a huge number of plants. Because of the limited available area, high-quality buds are especially vital because the potential production size is limited. Due to the fact that heat might become an issue in a tiny grow environment, an LED grow light with high power will be your best option. Consider purchasing a full-spectrum LED panel with an actual power ranging from 300 to 600 watts (our recommendation).

Supplement the LED with blue-spectrum fluorescent lights or comparable LED bars, which should be hung vertically next to the plant to provide additional illumination (s).

Fluorescent bulbs will generate some heat, but utilizing an LED as the primary light source keeps the temperature under control. It is recommended that LED bars be used instead of fluorescent tubes in order to avoid the heat issue completely and to avoid the need to change bulbs.

Specific Example:

Using a 600 watt LED light above the plants and four LED bars, or four fluorescent bulbs of 45-60 watts each, hanging around the perimeter of the grow room, you might achieve an area of 3 by 3 feet. This 2 foot, 24 watt veg/clone bar is great for growing vegetables and clones. It is more expensive than a fluorescent bulb, but it saves you a lot of money in the long term because of the lower power consumption and the absence of bulb changes. If fluorescent lights are more your style, you can get them at any department or hardware store, as well as online at Amazon (here’s an example of an excellent, inexpensive bulb).

This 24 watt bloom bar is the most effective LED bar for this application.

Choose the entry-level Secret Jardin Hydro Shoot tent if you want to keep prices down while still getting good quality (link goes to the 3×3).

Lighting to Maximize Yield When Growing in a Spare Room

If you are growing in a spare room, you will still have a limited amount of space, but it will be far more than if you were growing in a closet. It is much more critical to keep your grow area isolated from the rest of the world. Find a nice grow tent that is large enough to accommodate your plants while still fitting comfortably within your space. If you’re growing in a tent, you’ll want to make sure it’s well ventilated. For the above lighting, I’d propose using LEDs once more to assist keep the temperature down and reduce heat.

Specific Example:

Choose one NextLight Mega grow light for every 12 to 16 square feet of space, or one NextLight Core grow light for every 4 to 9 square feet of space. Hang LED bars or fluorescent lamps between the plants in the same manner as previously, but increase the voltage. To save money, use two of the 24 watt bars (or the bigger 42 watt, 4 foot bars to cover twice the space) instead of one. You may also utilize fluorescent bulbs ranging from 125 to 250 watts. LED is preferable since it consumes less electricity and generates less heat than other lighting options.

Use primarily blue-spectrum bars or bulbs into your grow, but don’t be afraid to incorporate some red-spectrum bars or bulbs as well, especially during the latter two weeks of the grow cycle.

Medical Growers With Strict Plant Count Limits

When you only have a limited number of cannabis plants to deal with, you want to get the most out of each plant in terms of development and output. To do this, place each plant in a big 20-gallon pot and provide it with its own NextLight Mega Pro (or 1000 watt HPS grow lamp) that will feed it from above the soil. This should be supplemented by 400 watt naked (no reflector) incandescent lights (remember, you need a ballast for each bulb) suspended vertically where the rows between the plants cross (I.e.

  1. It has been made simpler by bundling a kit that contains the socket, a bulb of your choosing, and a high-quality micro ballast in one convenient package.
  2. This is attempted to be illustrated in the following image: Yeah, I know.should have hired a designer, or my 4-year-old nephew, or anything.).
  3. There is, without a doubt, one significant disadvantage.
  4. Make use of air-cooled reflectors to prevent the majority of the heat generated by high-pressure sodium lamps from entering your growing space (or just use LED lights).
  5. More than 65 watts per square foot of growing space is provided by this configuration.

You could simply use smaller lights and grow smaller plants with the same setup because it is more than double the normal suggested quantity (30 watts per square foot). You could, of course, go much further in terms of size. Just make sure you don’t overdo it with the heat.

Getting Maximum Production From Your Grow Space

This configuration takes the previous one to a higher level of sophistication. To provide each plant with a 5 by 5 foot area with lots of room at the roots, extra-large beds are employed. A NextLight Mega Pro is suspended above each plant (or a1000 watt HPS light in a large reflector, air cooled ideally). On the sidewalls of the plants, 600 watt HID lights are suspended naked between the plants, one bulb beside each plant. It’s important to remember that each bulb requires its own ballast. Check out our kits, which contain everything you need to get started (socket, bulb, ballast).

Then, in the final phases, when the plants have finished growing vertically and are at the peak bud phase, switch to high-pressure sodium lighting.

Adjust plant spacing and vegetative periods as needed, and make certain that the temperature is kept under control during the process.

Although these final two examples may seem a little “out there” for a starting grower, I thought they would be fascinating to add regardless of your level of experience.

  1. Make use of a powerful overhead light, such as a full-spectrum LED or a high-pressure sodium lamp. Side lighting with a blue spectrum, either fluorescent or metal halide, should be used in conjunction with the main lighting. For the final phases, it is possible to switch to side lighting with a red spectrum.

If you decide to give it a shot for your next grow, please report back on your experience. We’d also like to know what kinds of lighting settings you use and which ones you’ve found to be very successful (as well as which ones you’ve discovered to be less effective).

Choosing the Right Light for Your Grow Tent

The usage of grow tents has increased dramatically in popularity over the last few years. This type of method appeals to both amateur farmers and seasoned growers because of its comfort and ease of usage. In spite of this, as our expertise of indoor grow tent cultivation continues to increase, we are always reevaluating critical components of these setups, such as grow lights. While the advantages of using grow tents for indoor cannabis growth are undeniable, there are some disadvantages to using these setups as well.

As a result, growers have difficulties while attempting to use horticultural equipment that was designed for broad expanses in the restricted space of a tent.

It might be difficult to grasp how horticulture lighting would perform in a tiny environment such as a grow tent, even if today’s horticultural lighting is excellent in practically every aspect.

It is the cultivators’ responsibility to discover which technologies will function best in grow tents because lights are not designed expressly for this type of arrangement.

What is Unique about Cultivating Cannabis in a Grow Tent?

Grow tent cannabis production is distinct from other forms of cannabis growing because of the architectural restrictions that develop as a result of the restricted square footage available in these systems. The limited enclosure formed by the grow tent has an immediate impact on crucial environmental elements like as temperature, humidity, and ventilation, among other things.

Spatial Constraints

When growing cannabis in a tent, the most important consideration is the restricted amount of space available. In conjunction with adequate space, the ambient conditions of your grow environment have an impact on every aspect of it. It is essential to consider the limitation of available space when looking for a grow light at every stage of the process since limited areas exacerbate environmental anomalies such as excessive heat emitted by certain light bulbs. A 2×2 foot grow tent is now available on the market, while a 10×20 foot tent is the largest available on the market.

Temperature

Temperature is a significant environmental issue that all tent growers must take into consideration. Cannabis thrives in temperatures ranging from 75 to 85 degrees Fahrenheit, as most producers are aware. In order to keep your tent running within this optimal temperature range, one of the most important aspects to consider will be your choice of grow light (or grow lights). Growing under a grow tent restricts your ability to regulate ambient temperatures with standard means such as air conditioners because of the tight quarters.

These do-it-yourself configurations are frequently big and take up important floor space in a location that is already limited.

Airflow

The amount of airflow in a grow tent is directly related to the amount of space available and the temperature within. The cultivation of cannabis is most successful in arid areas, where soils and growing mediums may completely dry out between watering cycles. Achieving optimal humidity control while also ensuring adequate ventilation is essential in preventing the development of dangerous microorganisms such as powdery mildew. Every five minutes, the air in a grow tent should be completely swapped in order to maintain ideal cannabis growth conditions.

In conjunction with your choice of grow light, your airflow system will be influenced by the quantity of heat produced by the light.

In comparison to others, some of these arrangements will be more clunky and less practical.

Different Grow Lights for Tent Cultivation

Traditionally, indoor growers have had the option of customizing their grow lights to meet the specific demands of their specific growing environment.

Listed below is a basic explanation of how different grow lights perform in grow tents.

Single-Ended High-Pressure Sodium (SE HPS)

Singe-ended high-pressure sodium (SE HPS) lights have been the preferred lighting choice of cannabis farmers for decades since they provide excellent results for both vegetative development and blooming. Furthermore, SE HPS lamps are cost-effective and provide a broad spectrum of useful PARlight for cannabis plants, making them an excellent choice. Inexperienced tent growers on a tight budget will find SE HPS lights to be a highly appealing solution for their growing needs. Despite the fact that these lights generate a lot of heat, the hot air may be vented using hoods, ducting, and an inline fan.

Grow tents are compatible with SE HPS lights.

Furthermore, it might be difficult to correctly arrange all of this equipment within the confines of a tent due to its tight fit.

Double-Ended High-Pressure Sodium (DE HPS)

The cannabis sector has been swept up in the popularity of double-ended high-pressure sodium (DE HPS) lights during the past decade. As a result of its consistent and powerful PAR light output, DE HPS lights are used by many of today’s commercial companies. When it comes to huge commercial grow rooms and greenhouses, DE HPS lights have shown to be effective; nevertheless, they are not suitable for usage in a tent. Because of the intensity of the light they generate, DE HPS lights must be installed at least three to five feet above the ground level of a garden canopy to be effective.

As was the case with SE HPS lights, DE versions are equipped with air-cooling systems.

As a result of this, as well as the requirement to suspend them high above the garden canopy, they are impracticable for use as grow tents.

Light Emitting Diode (LED)

Light-emitting diode (LED) lights are the most recent advancement in the field of grow light technology. Originally, LEDs exclusively used the blue and red light spectrums, which were primarily intended for the vegetative development of cannabis plants. However, in recent years, full-spectrum LED lights have been developed that emit enough PAR light to allow for the cultivation of large cannabis flowers. One of the most significant selling aspects of LEDs is their ability to operate at extremely low temperatures.

Based on these facts, the biggest disadvantage of LEDs is their cost, which is more than that of alternative lighting sources, but costs are decreasing with time.

Their low operating temperature also reduces the requirement for auxiliary equipment like as hoods, fans, and ducting that may be heavy and cumbersome. LEDs will save you time and frustration during the planning stage, and they will allow you to utilize more square footage within your tent.

Which Light is Best for Cultivating Cannabis in a Tent?

Grow tents are here to stay, and there is no denying it. If you are an experienced or novice grower, it is probable that you will be able to discover a useful application for these handy starter kits. When preparing for such procedures, there are a number of critical aspects to take into account. In the end, we determined that LED lights are the most appropriate choice for grow tent production after carefully analyzing the many alternatives available. Given the primary obstacles of growing in a grow tent in terms of available area, temperature, and airflow, LEDs make your setup easier by reducing the need for complicated air-cooling systems in a limited amount of space.

LEDs have been particularly designed to perform in extremely close proximity to plants, hence maximizing the usefulness of the technology.

When you find yourself having to add a slew of extras to a single piece of equipment in order for it to function properly, it is probable the piece of equipment is just not appropriate for the task.

What Size Grow Light Do I Need? (The Simplest Way To Figure It Out)

It might be difficult to figure out what size grow light you need for your plants. A variety of elements come into play, like the sort of lighting you prefer, the plant(s) you are growing, the size of your grow space, and so on and so forth. In this essay, I break down the problem and attempt to make it as straightforward as possible. Before you begin, you must determine the light requirements of your plant(s), the sort of lighting you intend to employ, and the size of your grow space. 1. Requirements in terms of lighting When it comes to the light need, all you really need to know is whether it has a high or a low requirement for light.

  • Herbs and lettuce, for example, are examples of plants with minimal light requirements since they do not blossom.
  • The Kind of Lighting To be on the safe side, use fluorescent lights if you just have one (or maybe two) plants and LED or CMH lights otherwise if you are unclear which sort of illumination you will require.
  • 3.
  • Alternatively, you can measure the plant (s).
  • It is time to get started once you have obtained those three pieces of information.

Scroll down to the bottom of the page to identify the sort of lighting you intend to utilize. In order to determine what size of light you require and how many lights you require, if you require more than one, follow the instructions.

How To Determine The Size (And Number) Of Grow Light(s) You Need

I’ll start with high pressure sodium and metal halide lighting, then go on to compact fluorescent, then LED, and lastly fluorescent.

What Size HPS And MH Lights Do I Need?

High pressure sodium and metal halide lighting are the most straightforward types of lighting to understand (along with CMH below). There are two approaches that you can take.

By Coverage Area

It is simple to determine which light(s) will best cover your grow space if you know the size of your grow space (for example, the size of your grow tent). According to the most commonly used MH and HPS bulbs, the following approximate maximum coverage areas may be achieved with these wattages:

  • 150 watts: 2 x 2 feet (or 4 square feet)
  • 250 watts: 2.5 x 2.5 feet (or 6.25 square feet)
  • 400 watts: 3 x 3 feet (or 95 square feet)
  • 600 watts: 4 x 4 feet (or 16 square feet)
  • 1000 watts: 5 x 5 feet (or 25 square feet)
  • 1500 watts: 5 x 5 feet (or 25 square feet)
  • 2000 watts: 5 x 5 feet (or 25 square feet)

You should be able to determine which size light is appropriate for you and how many lights you require based on this information. If all else is equal, 600 watt lights are the most efficient (meaning they produce more light per watt of power consumed) and 1000 watt bulbs are the second most efficient, so you should always check to see if they would work in your space first. Consider the following scenario: you have an area that measures 10 by 20 feet, or 200 square feet. That is completely divisible by 4 (the 150 watt bulb) or 25 (the total number of watts) (the 1000 watt bulb).

  • The eight 1000 watt bulb option is far superior.
  • Although the area is not exactly divisible, 200 divided by 16 gets you 12.5, which means you would only need to utilize 12 or 13 fixtures to make them all fit in the space.
  • One thing to keep in mind is that this is based on the maximum coverage regions available for each bulb power.
  • If you want to provide your plants enough of light in order to increase yields, the following approach makes it crystal apparent and provides greater outcomes than the previous one.

By Wattage

The alternative method for determining your MH and/or HPS lighting requirements is to look at the wattage requirements. Cannabis, for example, requires between 30 and 70 watts per square foot of canopy to thrive, making it an ideal plant for growing indoors. I would recommend a minimum of 50 watts per square foot of floor space. If money is not a problem and heat is not a concern, increase the power to 65 watts per square foot. Let’s have a look at the previous example once again. The one with a 200-square-foot floor space, to be precise.

In such case, ten 1000-watt lights (10,000 / 1000 = 10) or seventeen 600-watt bulbs (10,000 / 600 = 16.67, which we round up to 17) would be required.

By working backwards, we can see that the preceding technique would provide coverage of 40 watts per square foot (eight bulbs each at 1000 watts = 80,000 total watts divided by 200 sq ft area = 40 watts per square foot).

Despite the fact that there is still plenty of light, we would achieve better outcomes if there was more light. You may check my reviews of the best bargain HID kits if you’re not sure which brand is the best choice.

What Size CMH Grow Light Do I Need?

Because there are just two typical wattages available: 315 watts and 630 watts, ceramic metal halide is much simpler to figure out than incandescent (which is a fixture with two 315 watt bulbs in it). One way to think about them is to examine the 315w bulb, which is comparable to 600w of MH or HPS light, and the 630w twin bulb fixtures, which are equivalent to 1000 watts of MH or HPS light. This implies that a 315 watt light will cover up to 44% of the area, while a 630 watt fixture will cover up to 55% of the area.

Check out my reviews of the best-value ceramic metal halide lighting kits if you aren’t sure which type of light you want.

How Many Watts Per Square Foot For LED Grow Lights?

In order to decide what size LED light(s) they require, most people use the wattage per square foot method, however this is not the only one. In addition, it is not the most exact method, but it is an excellent balance between accuracy and simplicity. Simply put, selecting how strong an LED grow lamp to purchase and how many of them you require is the most difficult task of all when it comes to growing plants under artificial light. This is owing to the wide range of lights available, as well as the fact that most manufacturers flat out lie about the specifications of their products.

In this case, there are three options to examine.

Using The Coverage Area Provided By The Manufacturer

When purchasing lights, most manufacturers disclose the coverage area of their lights, which you may use to determine which light will be able to adequately cover your grow space. Isn’t it nice and straightforward? If only everything were that simple. Unfortunately, many manufacturers (mostly Chinese, but also a significant number of American companies) overstate the area that their lights will successfully cover. The coverage area for a low-light-requirement plant (and not one with a high requirement, such as marijuana) or the coverage area for vegging, which is always bigger than the coverage area for blooming, are examples of what they could tell you to do.

Unfortunately, I do not have a decent answer for this problem at the moment.

If you’re looking for information about lights that I haven’t examined, you’ll have to go online.

Using The Wattage

If you want to grow a plant that requires a lot of light, you should aim for 30 to 40 watts per square foot of canopy area. Once again, there is a major issue to contend with. The majority of LED manufacturers provide both an actual wattage and a theoretical wattage (what the light would consume if the chips were all driven at full power, which they never are). Important! It is preferable to use real wattage for this calculation. This need a little investigation in order to determine the real wattage of a light bulb.

  1. Many Chinese manufacturers do not even employ theoretical watts in their products.
  2. Roleadro’s 2000 watt light, for example, only consumes 230 watts in reality (Roleadro is one of the absolute worst offenders when it comes to blatantly making up numbers).
  3. They frequently bury it in the bottom of the page, but it is virtually always visible at the top.
  4. Consider the following illustration.
  5. 6000 watts total would be required to illuminate that area with LED grow lights if we were to go for the lowest possible wattage per square foot of 30 watts per square foot of light.
  6. This lamp has an actual power of 615w, therefore if we used 10 of these, we would have a total of 6150 watts.
  7. Consider the following scenario: you have a 3×3 grow tent.
  8. At 30 watts per square foot, you’d need a total of 270 watts to cover the area.
  9. As a result, to illuminate this space, you would want an LED grow lamp with an actual wattage of 270 to 360.
  10. As a result, the efficiency of the light is not taken into consideration with this technique.
  11. However, the actual output will vary widely from one manufacturer to the next, and wattage is regarded as a decent indication for the quantity of light a fixture would offer.

Phlizon lights are simply more energy efficient than traditional lights. As a result, we arrive at the most accurate method: relying on the original output.

Using The Output

While this approach is the most accurate, it is also the most difficult to utilize since many manufacturers do not publish a great deal (if any) of useful information on the output of their lighting fixtures. This is especially true when it comes to Chinese-made products. Even if they do offer output information, they frequently just take a reading dead center underneath the light, which is where the output is at its most powerful, rather than everywhere else. They do not provide readings for the remainder of the coverage area, which is frequently due to the fact that the light is quite feeble around the outside of the region.

  • I’m sure you’re curious in how output is assessed and what level of output is considered satisfactory.
  • It is measured in units of micromoles per square meter per second and informs you how much light is present in the wavelengths that plants employ for photosynthesis.
  • Plants should receive between 300 and 600 umol/m2/s during the vegetative stage and between 600 and 1000 umol/m2/s during the bloom stage in order to get best results.
  • You want to acquire at least 100 umol/m2/s, but preferably more.
  • A PPFD footprint will be provided by reputable manufacturers (also referred to as a PAR footprint or a PAR chart).
  • Most of the better lights will not have sky-high readings in the centre (and hence much lesser readings around the perimeter), but will instead have decent readings all across the place (even if the manufacturer just supplies the number for the middle).

What Size Fluorescent Grow Light Do I Need?

Fluorescent lights are only useful for a couple of plants at a time. They become inefficient if they are used for any longer than that. This article explains how to calculate the number of fluorescent bulbs you will require. Instead of reading that, just know that you’ll need between 60 and 100 real watts per square foot of growing space to have a good yield.

What kind of grow lights do you need for a grow tent?

To understand what type of grow light is required for a grow tent, it is first necessary to comprehend what a grow tent is. This is a specialized gadget for growing plants in controlled indoor environments, and it consists of the following components: 1.A growing tent, also known as a grow tent, is constructed of sturdy fireproof material that is sufficiently sealed to maintain an appropriate microclimate within. The interior surface of the grow tent is reflective, which aids in the uniform distribution of the light emitted by the grow lights and the maximization of their effectiveness.

It consists of fans for supplying and exhausting air, as well as a filtering system for removing strong and unpleasant aromas from the environment. The growing medium used is either a hydroponic system or growbags with drip watering. 4.Lighting — high-powered grow lights.

Maybe the most common grow light is suitable for plants?

An regular incandescent light bulb that offers adequate illumination for a human is not at all suited for growing plants since photosynthesis will not take place due to the weak illumination. By placing a dim light bulb closer to the plant, it will cause the plant to dry up and burn due to the fact that the bulb, on average, becomes rather hot. tent for growing plants Grow lights are distinct from one another, and they differ in terms of their operating principle:

  • The following types of grow lights are available: low and high pressure sodium gas discharge grow lights (HPS, HPS)
  • Fluorescent grow lights (ESL, CFL)
  • And LED grow lights (LED)

Additionally, while determining which grow lights are suitable for a grow tent, you should be aware that grow lights have a different illumination spectrum than one another and vice versa.

Light calculation in a grow tent

A frequent issue on growing sites is the calculation of light in a grow tent; you can also find ready-made light calculators (calculation of lighting per area), where you only need to enter the dimensions of the growing area: length and breadth. In this case, a 70-watt DNaT or an 80-watt CFL or an ESL will enough for a 40-by-20-foot space, respectively. When using a 20 watt fluorescent light, it is crucial to know that the plant will develop, but in a much poorer way: more slowly and with lesser yields.

Square LED DNAT ESL
30×30 cm (0.09 sq.m) 50 Watt 70 Watt 100 Watt
40×40 cm (0.16 sq. m) 70 Watt 100 Watt 150 Watt
50×50 cm (0.25 sq.m) 115 Watt 150 Watt 250 Watt
60×60 cm (0.36 sq.m) 180 Watt 250 Watt 400 Watt
90×90 cm (0.8 sq. m) 360 Watt 400 Watt
110×110 cm (1.2 sq. m) 530 Watt 600 Watt
130×130 cm (1.7 sq. m) 750 Watt 1000 Watt

How to choose a grow tentlight

What type of grow tent light should you use? Obviously, you must start with the size of the space: the greater the area, the less effective fluorescent lights are, and sodium gas-discharge lights will have the biggest impact on very huge areas. Choosing the right light for your grow tent can be challenging, especially if you have a vast space to cover. It is crucial to note that fluorescent (ECL) lights are not feasible for huge areas. It is more comfortable for plants to grow if the space is between 0.36 and 0.36 sq.m.

  • However, it is important to have enough ventilation and to keep in mind that fluorescent lights may get quite hot.
  • Small and big grow tents are both suitable for use in this product.
  • LED lights are the most up-to-date and highly sophisticated type of lighting available (LED).
  • The grow room light that you may get from Growpro will be of great quality in and of itself, but it’s crucial to choose the type of light you want for your unique requirements.

LED grow tent Lights

LED grow tent lights are a contemporary, technical, and environmentally friendly option. In this case, the LED modules are made up of several LEDs connected to a semiconductor through which a current is conducted, which results in the emission of photons (light).

In order to create radiation with varied wavelengths – ranging from infrared to ultraviolet – these lights make use of a range of semiconductor materials. The following are some advantages of LED grow lights:

  • Growth requires the capacity to get light from any spectrum, which is why growing lights are used. In an ideal situation, two blocks of such lights would be required – one for the growth phase and another for the blossoming time
  • LED lights consume less power and generate little heat, making it easier for the planter to maintain control over the environment in the grow tent
  • In addition, LED lights have a long life span. Experienced growers, on the other hand, point out that the life of an LED light will only be as long as indicated if the light is operated under optimal conditions.

The expense of LED lights is maybe the single disadvantage of using them. Growpro offers to purchase a Secret Jardin Tled 26W 55cm Blooming Led light, which is a very affordable LED light that is perfect for supplementary illumination during the flowering period, lights the lowest sections of plants, and boosts yields. It is made up of 144 diodes with a power of 0.18 watts apiece. Color temperature ranges from 3000K to 2100K, with infrared being the highest. Growing lights are also available in this department, including the Growstar 300W spectrum 7.7 led light – high-tech and 300 Watt (in terms of efficiency, it is equivalent to LED lights 750 Watt and DNAT 1200 Watt).

The angle of reflection is approximately 120 degrees.

It should be noted that the light is not directed in all directions, but rather is collected in a beam, the extent of which is determined by the distribution lens.

Sodium lights for grow tentes

Sodium lights for grow tents are the industry standard for artificial plant illumination. Works in conjunction with:

  • A control system consisting of the throttle and the IZU (pulse ignition device)
  • A capacitor

The DNaT is comprised of a flask with high pressure sodium vapor contained within it, as well as an arc tube composed of ceramics with aluminum oxide coating (resists corrosion from sodium vapor). DNaT is a gas-discharge lamp that is activated by an IZU and a choke combination. The cost-to-efficiency ratio of these lights is quite favorable, and as a result, they are the industry leaders in the field of growing box lighting. It has an extremely high luminous efficiency, producing around 96-150 lumens per watt of electricity.

Monochromatic radiation, a yellow-orange glow, and a red spectrum predominate, which is ideal for growth throughout the autumn-winter transition period.

  • It may get fairly hot
  • The ignition is sluggish (it can take several minutes to ignite)

Fitolights for grow tentes

Grow tent phytolights are a product of space technology and are intended for use in settings where there is no light at all, such as in a greenhouse. Modern phyto-lights are made of LEDs, and there are several reasonably priced solutions available: for example, you may buy a phytolight for plants and construct your own phytolight for a few dollars. The following are some of the advantages of phytolights:

  • These devices have a lifespan of 5-10 years, emit no heat, do not break when the voltage lowers, maintain constant intensity across the spectrum, require minimal energy, are ecologically friendly and safe, and have a low carbon footprint.

Phytolights are classified into the following categories:

  • Plant development is aided by the use of bicolor – blue and red – dyes, which stimulate photosynthesis and encourage growth. Additionally, it can be used as a complement to natural light. Flowering and fruiting are stimulated by multispectral light, which includes warm white, red, blue, and infrared. Even in the absence of light, a complete spectrum – sometimes known as “personal sun” – harvest may be obtained.

UV light has also been shown to have bactericidal characteristics, but infrared radiation has been shown to encourage plant growth.

Energy saving lights for grow tentes

Fluorescent grow tent lights operate on the following principle: a spark passes between the electrodes, causing ultraviolet radiation to be generated in mercury vapor, which is then converted into visible light by a phosphor applied to the inner surface of the tube (a special substance that converts the energy it absorbs into light, known as luminescent).

ESL lights provide between 50 and 70 lumens per watt of power, depending on the model. ECL lights employ a variety of various kinds of phosphor (which has an effect on the spectrum of light emitted):

Lights with a “cool” spectrum – 6500K – are used to stimulate plant germination and vegetative development throughout the time of germination and vegetative growth. The “warm” spectrum (about 2700K) is required during the blooming phase, while the “daytime” spectrum (approximately 4100K) is universal, appropriate for use throughout the plant cycle or as supplemental illumination at any time. The drawback of fluorescent lights is that they generate a great deal of heat, which can cause the plant to dry up and burn if it comes into contact with them during the growing process.

This has the benefit of being available, consuming little power, not requiring any additional cooling, and being able to be linked directly to the network without the use of ballasts.

There is a broad variety of ESL lights available in the Growpro shop for growers, from a cheap longitudinal compact fluorescent phytolight for a MASTER PL-L 55W / 865 / 4P 1CT grow tent with a power of 55 watts to a high-powered compact fluorescent phytolight Advanced Prostar CFL Grow 200w (200 watts).

CMH lighting

CMH is more often used in horticulture than in other fields. CMH lights provide a broad spectrum of light that is more similar to the sun than any other type of high-intensity discharge light. The CMH luminaire can be utilized as the primary light source for SOG (or Sea of Green) applications, or as a full spectrum secondary light source for big blooming operations, depending on the application. CMH lighting is both cost-effective and dependable. It is possible to lower your energy expenses by up to 70% by using the Ceramic Metal Halide System to boost the development and output of your plants.

We carry top CMH brands such as Philips, Hortilux, Lightspeed, Silverstar, and many others.

The Different Grow Room Lights and How You Use Them: Part IV: Fluorescent and LED Lights

T12, T8, and T5 fluorescent tubes are two types of fluorescent lights that are commonly used in grow rooms: compact fluorescent bulbs (CFL) and fluorescent tubes (T12, T8 and T5 fluorescent tubes).

Compact fluorescent bulbs (CFLs)

CFLs are ideal for use in compact grow rooms with limited space, and they are particularly effective for delicate seedlings, cuttings, and young plants that are just getting their feet under them. AdvantagesCFLs:

  • They’re affordable
  • They don’t generate much heat
  • Don’t consume a lot of electricity. Are simple to locate
  • It is not necessary to use ballasts in order to operate

If you just want to care for one plant that will not grow taller than a foot in height, you may theoretically utilize CFLs during the whole life cycle. Most of the time, though, you’ll only want to use CFLs to grow seedlings and cuttings from seed.

When exposed to this gentle, cold light, such sensitive plants thrive. In order to soften light and dissipate heat more efficiently, use more low-wattage lights rather than fewer high-wattage bulbs. Factors to considerCFLs are not:

  • Appropriate for use in big grow rooms
  • Except when used for light supplementing with other light sources, this is useful for plants that are 12 inches or higher in height. Suitable for the blossoming stage of the plant

Fluorescent tubes

When used in conjunction with high pressure sodium and metal halide bulbs, fluorescent tubes may cover the whole spectrum of visible light, just as they do when used individually. They are, on the other hand, ideally suited for seedlings, clonings, and other tiny plants. T12 tubes are being phased out in favor of T8 and especially T5 tubes; the number refers to the diameter of the tube: T12 = 1 inch, T8 = 1 inch, T5 = 1 inch, T12 = 1 inch, T12 = 1 inch, T12 = 1 inch, T12 = 1 inch, T12 = 1 inch, T12 = 1 inch, T12 = 1 inch, T12 = 1 inch, T12 = 1 inch, T12 = 1 inch, T12 = 1 inch T12 has a diameter of 12/8′′ (1.25′′).

Benefits

  • For little plants and seedlings, T5s are the ideal choice since they provide the most soft light. T5 ballasts produce no heat, noise, or vibration, hence they are extremely energy efficient.

Considerations

  • T5s are not recommended for plants that are more than 12 inches tall, or 24 inches tall for T4s. For later vegetative phases of development or flowering, the light source is inadequate.

Finally, there are the “new kids on the block,” which are LED grow room lights. LEDs have a number of advantages.

  • Heat dissipating fans are incorporated within the cabinet. There is no need for ballasts because the plug is straight into the wall. When compared to HID lights, they consume significantly less energy. In most circumstances, because they don’t create much heat, there isn’t a need to exhaust or manage the heat. It is possible that this substance can promote efficient development even during the blossoming stage.

DisadvantagesLEDs:

  • Are still too pricey. Are not as tried and proven as high-intensity discharge (HID) lights for producing good crops
  • When it comes to quality, it might be hit or miss.

The consensus

While LEDs are an exciting new invention, the quality and strength of the bulbs are still subject to variation; the LED business is still in its early stages of fast expansion and has not yet been “shaken-out.” Because of this, as well as the fact that LEDs are still prohibitively costly, HIDs continue to be the industry standard for the time being. However, as technology advances and becomes more standardized, as well as as prices fall down, expect LEDs to take over as the primary source of illumination in your grow room.

Best LED Lights for (3’ x 3’) Cannabis Grow Tent

IMAGE ABOVE: Four of the best LED grow tent options available at GrowersHouse for a 3′ by 3′ grow tent are shown. The following brands are represented: Horticulture Lighting Group (HLG), Kind LED, California LightWorks, and SpectrumKing. Grow light technology using LED (Light-Emitting Diode) technology has advanced tremendously over the last many years, enhancing both functional and cost-based efficiency. In the past, HID (High Intensity Discharge) lamp sets were the ‘standard’ for developing marijuana in an indoor grow room, but LEDs have changed that.

With the legality of cannabis production becoming more frequent across the country, compact grow tents have become an increasingly popular alternative for folks who want to safely house and efficiently generate big quantities of cannabis with less work than they would otherwise.

Specifically, we will discuss the best (5) LED lights for use in a grow tent (3′ by 3′), which will be discussed in this article.

Advantages of LED Lights for a Grow Tent

IMAGE ABOVE: (LEFT)(400-Watt)(HID) (400-Watt)(HID) (High Intensity Discharge) Included in the lamp package are an HPS+MH compatible ballast, a Digilux (400W) HPS bulb, and a driver (120-240VAC) Cord(RIGHT)(320W) The Stealth LED Fixture by Prism Lighting Science LEDs have a number of advantages over other forms of lighting that are routinely employed, but the most significant is that they give growers with the most efficient source of photosynthesis (photosynthesis) (Photosynthetically Active Radiation).

With another way of putting it, LEDs emit wavelengths that fall within the optimal PAR range of (400-700nm) while using the least amount of energy possible (Watts).

Example: Even the most energy efficient (double-ended) (HPS) (High Pressure Sodium) (HID) lamp has a PAR energy efficiency of (2.0 umols/Joule); on the other hand, an LED lamp will typically have a PAR efficiency of (2.0 umols/Joule). The following are a comprehensive list of the advantages of LEDs:

  • Massive energy savings (as compared to most HIDs, the efficiency of oper watt energy utilized is around 40-50 percent larger)
  • LED Diodes have long life spans of (50,000 or more hours), but high intensity discharge (HID) bulbs only have a life span of (2,000 – 3,000 hours). LED Diodes do not require a filament to operate
  • Capability of Customizing Spectrum (Vegetable growth is fostered by colder (Blue) tints of light, whereas flowering is stimulated by warmer (Red) tints of light)(More effective supplementary light source for greenhouse applications)
  • Capability of Customizing Spectrum LEDs are more compact (take up less room than other lighting options)
  • LEDs are more energy efficient. Lower heat output (helps to keep the grow tent cooler and reduces the risk of fire)
  • The ability to customize light angle (LEDs utilize lenses instead of reflectors) (allows light to penetrate the canopy more efficiently)
  • And the ability to customize light intensity. Ability to customize dimming capabilities (efficient energy consumption from seed to harvest)
  • Ability to customize dimming capabilities Unlike compact fluorescent lights (CFLs), it does not contain any mercury.

The following are the disadvantages of using LEDs in a grow tent: The most important downside of using LEDs is the significantly larger initial investment required. In general, an LED will cost around twice as much as a high-intensity discharge (HID) bulb of the same power. However, if a farmer has the financial resources, the additional cost of the LED will be recouped over time as a result of the energy savings and significantly longer life expectancy. In colder climates, however, LEDs can represent a significant disadvantage, especially when cannabis is being grown.

Instead of an LED fixture, people who prefer to use a (3′ x 3′) grow tent in a location with low humidity might use a (400-Watt)MH/HPS (HID) Lamp, which has a higher output.

Determining Specifications of Required LED

In order to achieve different phases of cannabis-based development, varying PAR intensities and DLI (Daily Lighting Integrals) are necessary. In addition, by applying certain PAR spectrums, it is possible to stimulate specific growth phases, hence enhancing total harvest yields. For your consideration, there are two (2) options: Option 1: Use (1) powerful LED with wide spectrum–lower capital cost + easier to maintain-OR-Use(2) powerful led with different spectrums–one with cool spectrum and the other with warmer spectral ranges–increase cannabis yields.

  1. The most prominent PAR wavelengths absorbed by chlorophyll AB are (430nm = Blue) and (660nm = Red) in order of importance.
  2. Over a 24-hour full day period, the (DLI) (Daily Light Integral) represents the entire amount of time crops must be exposed to (PAR) light on a daily basis.
  3. Important Lighting Requirements include the following: Vegetative State|
  4. The reproductive state necessitates between (475 and 800 umols/m2/sec) of oxygen.
  5. The promotion of the (2) Primary Growth Stages of cannabis crops (Vegetative, Reproductive, and Flowering) may be accomplished by employing spectrums that are specifically tailored to each stage.

Cooler spectrums include larger ratios of blue to red PAR, which stimulates the formation of leafy green growth, whereas warmer spectrums contain higher ratios of red to blue PAR, which stimulates the production of flowering plants and flowers.

If Savings and Ease of Use are Preferred Over Optimal Cannabis Yields then Utilize–(1)(3′ x 3′) Grow Tent+(1) LED withWide (Full) Spectrumto cultivate cannabis through all growth stages.

Ahead of you is an image of the HLG Elite 225 – (225W) LED Fixture, which is a low-cost, high-efficiency lamp that incorporates full spectrum (white) as well as red (630nm) and far red (660nm) wavelengths, enabling the cultivation of cannabis through all of its growth phases while still promoting flower production during the plant’s reproductive growth. Additionally, dimming is included, which may be utilized to reduce the intensity of the PAR light for vegetative growth. This is by far the most popular way of at-home cannabis cultivation since it is the most cost-effective approach available.

Because a (3′ x 3′) Grow Tent has an area that is (0.836x) that of a (1 m 2), we will want an LED that has the capability of producing between:

(475 – 800)(umols/m 2 /sec) * (0.836)=(400 – 670)(umols/sec)@ (12-Hrs)(DLI)

In order to keep the PAR in a reasonable range during vegetative development, it is extremely recommended that you use an LED model that has dimming capabilities. For a (3′ x 3′) Grow Tent, the optimal fixture PAR intensity range for vegetative growth in a(3′ x 3′) Grow Tent is derived using the same calculation as previously but using the recommended PAR range for vegetative growth per unit area instead of the recommended PAR range for reproductive growth:

(230 – 385)(umols/m 2 /sec) * (0.836x) =(200 – 320)(umols/sec)@ (18-Hrs)(DLI)

ADVANCED LED with a configurable PAR spectrum, the California LightWorks SolarSystem 275 LED Fixture (seen above) is an excellent choice for outdoor lighting. Consequently, color combinations such as blue to red and other hues may be tailored to better fit the present growth phase of the cannabis plants concerned.
