How Tall Should My Grow Tent Be

How Tall Should a Grow Tent Be? (For Weed Plants)

When you make a purchase after clicking on one of the affiliate links on this site, Growing Marijuana World may get a commission. See the affiliate notice on the sidebar for more information. Because of my own recent experience with a 5′ grow tent and an Indica plant that is presently about halfway through flowering, I decided to write this essay on it. When it comes to growing marijuana indoors, five feet seems like a long distance, especially if you’re planning on doing some light stress training (LST) on the plants beforehand.

With a 5′ tent, you should train the plants by trimming them to allow the buds to grow to their optimum size without the tent becoming too large for the plants.

Using a larger grow tent will provide the best results in terms of producing the greatest amount of produce.

I’ll also attempt to address any other questions you might have about how tall your grow tent should be if I believe they’re relevant to this topic.

Is a 5’ Grow Tent for Marijuana Tall Enough?

You could conclude from the way I began this post that I am against the use of a 5′ tall grow tent, but I am not. As long as you are aware that your marijuana plants may need to be treated differently than if they were in a higher tent, you should be alright with a taller tent. I’m now cultivating a plant in a 3-gallon pail within a 5′ grow tent, and it’s doing well. It’s been a few weeks since flowering began, and the buds have now grown to be a couple of inches away from the LED grow lamp. I’ve turned the brightness of the light up to the maximum setting.

  • Having said that, I would never propose growing in a container as small as a 3-gallon container.
  • This provides your plant with extra space for roots, which results in larger buds.
  • Does that make sense?
  • Because it is an Indica plant, it is not need to grow to extraordinary heights, which is a positive thing.
  • When I grow my second marijuana plant, I aim to utilize the identical grow tent that I used for this one.
  • In case you’re not familiar with the terms LST or Topping, please read this article.

I’d recommend a higher tent for someone who is just getting started in the pastime. At the very least, 6′ to 7′ tall. On Amazon, you can get a good-sized grow tent that can accommodate two plants.

How to Maximize Yields in a 5’ Grow Tent

In order to get the most out of a 5′ grow tent, you’ll undoubtedly want to do something to increase the plant’s output. It is not difficult to get the most out of your plants with minimal effort. Here are a number of surefire strategies that will assist you in achieving your goals. The importance of training your plants when they are initially starting out is critical for producing the most buds possible in a 5′ grow tent. Once the plants are a couple of weeks old, it is beneficial to practice low stress training to ensure that bud growth is evenly distributed across the whole plant.

  1. The quality of your marijuana plants’ growth under a tent is greatly influenced by the amount of light and fertilizer they receive.
  2. You may, however, give the greatest lighting you can afford in order to as closely as possible duplicate the sun’s illumination.
  3. Plants and buds may be grown larger, resulting in a greater yield for you when the plant is ready to be cut down for harvesting.
  4. That is all there is to it.
  5. Your final output will almost certainly be higher with HPS lights than with LED lights; but, with today’s technology, LED lights are providing fantastic results in grow tents as well as other environments.
  6. If you are growing in a 5′ or any other size tent, using a big pot can allow you to optimize your harvests.

What Size Grow Tent for 2 Weed Plants?

Now that you’ve learned that the height of your grow tent is important, all that’s left is figuring up how much length and breadth you’ll need in order to properly grow two plants. I can tell you from recent personal experience that growing one plant in a 24″ x 48″ x 5′ high tent allows for more than two plants, but I’m not sure I’d advocate doing so in this situation. Only one plant, a heater, and one bucket of water were housed in that tiny tent for my purposes. It might be possible to accommodate more than 2 plants in the tent if you only had the plants in the tent; however, there would be little area for the plants to spread out.

However, for two plants, I’d recommend using (at a minimum) a grow tent that is at least 24″ x 48″ and 6′ to 7′ in height (at a minimum). You can utilize 5′ high tents if they are all that are available; but, due of the lower height, you’ll want to think about training the plant to compensate.

Conclusion

For the sake of concluding this post, I’d want to briefly discuss the significance of using a taller grow tent while growing cannabis indoors. The height of weed plants may reach great heights, especially if you’re cultivating Sativa plants. Even Indica plants, when cultivated in a huge container, can become too tall. You must also consider the fact that your grow light will be hanging from the ceiling, reducing the amount of height available for the plants to grow in. Learning how to train your plant, such as through LST or topping, will allow you to keep your plants shorter while also increasing the number of buds that end up sprouting on your plants.

If you have the financial means to purchase a 6′ or higher grow tent, I strongly advise you to do so.

Good luck with your next marijuana plant growth endeavor, regardless of the size of the tent you pick.

Detailed Guide To Choosing The Right Size Grow Tent For Your Plants

Are you unsure of the size of grow tent you’ll want based on the quantity of cannabis plants you intend to cultivate? I’ve broken down all of the criteria that need to be examined so that the decision-making process will take no more than a few minutes to complete. In general, you should have 22 feet of grow area per mature cannabis plant in your grow tent, according to the American Cannabis Association. You’ll also need to make room for other products such as a humidifier. These estimations are based on the assumption that you will not train your plants.

Depending on the training technique you choose, this might result in an increase in the amount of area required per plant.

By following the steps in this guide, you will have answers to the following questions:

  • What is the appropriate size grow tent for four plants? What size grow tent do you recommend for 8 plants? What size grow tent do you recommend for 12 plants? And so on.
  • What size grow tent should I use for autoflowers
  • What size should the grow tent be
  • How tall should it be
  • How to manage the height of your plant while it is growing in a grow tent
  • When looking for grow tents, there are a few more things to consider.

Finally, it boils down to how effectively you can utilize a particular area and whether or not you are taking efforts to guarantee that you are making the most of your space.

How many cannabis plants per grow tent?

All of these suggestions are based on the assumption that you will be planting in 3 or 5 gallon grow bags or buckets.

What size grow tent for 1 cannabis plant:

When growing one cannabis plant, I recommend a grow tent that is 24 inches by 24 inches by 48 inches.

What size grow tent for 2 cannabis plants:

In order to produce two cannabis plants, I propose a grow tent that is 24′′ x 48′′.

What size grow tent for 4 cannabis plants:

I propose a grow tent that is 48 inches by 48 inches by 80 inches in size for four plants.

What size grow tent for 6 to 8 cannabis plants:

I propose a grow tent that is 96′′x 48′′x 80′′ in size.

What size grow tent for 10 cannabis plants:

I propose one that is 96′′x 48′′x 80′′ in size. One 24′′x48′′ in. grow tent with one 24′′x48′′ in. Ten plants may be grown in a grow tent.

What size grow tent for 12 to 16 cannabis plants:

I propose using *two* 48′′x96′′x80 in. grow tents for a total of 12 to 16 marijuana plants.

What size grow tent for autoflowers:

Autoflowers typically reach a height of 3 feet. If you’re thinking of growing autoflowers in a grow tent, I’d recommend following the same requirements as those listed above. Here’s why: Even these autoflowers are smaller in stature, their branches may still span a significant amount of space when completely developed, despite the fact that their height is reduced. As a result, cultivating autoflowers in a grow tent will not result in significant space savings when compared to growing ordinary cannabis plants in the same space.

However, there isn’t a significant change in the quantity of room you’ll have.

Remember: These are general estimations based on the fact that a 3 or 5 gallon grow bag requires around 24 square inches of area per plant. I’ll outline strategies for managing the height and growth of your plants so that you can really fit this many plants into your grow tent in the sections below.

Determine the space needed per plant:

Cannabis plants may grow to a variety of sizes, many of which are within the control of the grower. Identifying how much room you’ll require for each plant is an excellent starting point for figuring how much overall area you’ll want in a grow tent or greenhouse. The three and five gallon grow bags are the most often used grow bags for cannabis cultivation at home, respectively. It is recommended to allow 2 gallons of soil for every foot of anticipated plant height as a general rule of thumb.

Grow Bag Size (Gal.) Height(cm) Diameter(cm)
1 gal. 16cm 18cm
2 gal. 20cm 22.5cm
3 gal. 23cm 27cm
5 gal. 27.5cm 31.5cm
7 gal. 29cm 36.5cm
10 gal. 31cm 40.5cm
15 gal. 33cm 46cm
20 gal. 40cm 51cm

Take a look at the diameters shown above for each of the grow bag sizes available. But you can’t stop there since the plant’s branches will eventually extend over the edge of the grow bag, requiring you to cut them back. When using 3 and 5 gallon grow bags, keep in mind that the cannabis plants can grow up to 13-15cm over the edge of the grow bag on any one side of the bag. In a 5 gallon grow bag, a mature plant is growing. Taking this into consideration, if you want to cultivate four plants in three-gallon grow bags, you need provide 44-49cm (16-17.5in) of room per plant in total.

If you want to grow in larger bags or buckets, you should anticipate that the branches may likely develop longer than the 13-15cm indicated for 3 or 5 gallon grow bags, so give your cannabis plants even more breathing room.

It is theoretically possible to cram them all into a 3x3ft grow tent, but there would be no room for a standing fan or a humidifier in such situation.

If you want a comfortable fit for four cannabis plants in 3-5 gallon grow bags (as well as a humidifier), a 44 grow tent (48′′x48′′x60′′ in.) is the best option.

How tall should my grow tent be?

You should absolutely stay with the usual 80-inch height on the 4×4 grow tents whether you’re growing cannabis or a tall vegetable plant like tomatoes. This is the reason why: Your grow light will dangle around one foot from the ceiling of the grow tent, and depending on the power of your grow light, you’ll need between 18 and 24 inches between the grow light and the plant surface of the growing environment. As a result, you’ve already utilized up 2.5-3ft of your available height. That leaves you with 3.5ft of space for your cannabis plants, maybe a bit more if you’re able to hang your grow light a little higher in the ceiling.

Of course, you can always put a dimmer on your grow lamp, but the light will not reach the plant’s lower branches if you do so. Using a little grow tent with a shorter height may be sufficient if you’re growing smaller plants such as succulents or house flowers in your garden.

Leave space for a humidifier in your grow tent:

Whether you’re growing cannabis or a tall vegetable plant such as tomatoes, you should absolutely keep with the regular 80-inch height on the 4×4 grow tents. The following are the reasons behind this conclusion: If your grow tent has a high ceiling, your grow light will dangle approximately one foot below it, and depending on how powerful your grow light is, you’ll need anywhere from 18 to 24 inches between it and the plant’s surface. Consequently, you’ve already used up 2.5-3ft of your available height in the first few steps.

Of course, you can always put a dimmer on your grow lamp, but the light will not reach the bottom branches of the plant if you do so.

Side note on grow tent humidity:

When it comes to cultivating cannabis, humidity is really important. Air that is too dry can inhibit development, whereas air that is too humid will promote mold or decay. Cannabis clones require 70 percent humidity since they absorb the majority of their water through their leaves while their roots are establishing. The remaining vegetative and blooming growth cycles can be completed at humidity levels of 50 percent or higher. Because tomatoes are primarily water, if you’re cultivating tomato plants, you’ll need 70-80 percent humidity to keep them healthy.

Controlling Plant Height In Your Grow Tent:

The ability to adjust the height of your cannabis plants will be critical if you want to successfully fit four plants into a 44 grow tent. Fortunately, there are a few strategies you may use to keep the height of your cannabis plant under control.

Switch plants to flowering phase at the right time:

When your cannabis plant has grown to half the height you want it to achieve at the end of the vegetative development period, reduce the length of the lighting cycle from 18 hours to 12 hours. The idea for this is that your plant will continue to grow the remaining 50% during the flowering cycle. This has shown to be a reliable rule of thumb, and it will assist you in growing plants that are the appropriate size for your grow tent.

Top Your Cannabis Plant:

Remove the top node of the main stem of your plant and discard it. Not only will this limit the height of the plant, but it will also allow hormones to seep downward to the bigger branches, assisting them in producing additional buds.

Low Stress Train Your Cannabis Plant (LST):

Your biggest branches should be bent over to the edge of the grow bucket and tied down in some way early on in their vegetative development. The branches will naturally bend upwards toward the light as a result of this strategy, but the eventual height of your plants will be reduced as a result. More information about LST may be found in my piece about increasing cannabis yields.

Use a smaller grow bag to grow smaller plants

In the event that you’re concerned about your cannabis plants taking up too much space within your grow tent, providing the roots a limited place to grow in might assist you limit their final growth.

Instead of a 5 gallon grow bag, a 3 gallon grow bag will suffice. A 7 or 10 gallon grow bag, on the other hand, may accommodate a larger-sized plant that will take up the whole grow tent, allowing for more root development.

Do More Cannabis Plants In One Grow Tent Equal More Yields?

Trying to cram as many plants as possible into a small space will not necessarily result in higher yields. As a result of overcrowding your tent, your plants will metaphorically be fighting each other for light and CO2. In a research conducted by McGill University on cannabis yields, one of the factors cited was proper plant spacing. Without a doubt, four plants in a 4×4 foot grow tent will produce more than two or three plants in the same size grow tent. I’m referring about the attempt to overcrowd 5 or 6 adult-sized plants into a grow tent with a diameter of 4 4 feet.

The same amount of harvest from 1 to 2 plants as you would from 3 or 4 plants might result if your lighting isn’t powerful enough, so make sure your illumination is enough.

Please see my guide on optimizing yields for more information.

That’s it!

You are now completely prepared to go out and get the appropriate size grow tent to accommodate whatever number of plants that you desire. These are broad suggestions that should be sufficient for most situations. When it comes to plant space, remember that more space is always preferable if you have the financial flexibility to go one size up and give your plants a bit more breathing room. However, the final decision is entirely up to you. If you’re planning on purchasing a grow tent in the near future, be sure to read my guide on selecting the correct sized grow tent fan, as well as my guide to the best grow tents on the market!

FAQ:

You have complete control over the amount of space each plant takes up in your grow tent. I estimate that you’ll need 44-49cm per cannabis plant if you’re using 3 or 5 gallon grow bags.

How many cannabis plants fit in a 4×4 grow tent?

You should be able to cultivate four cannabis plants in three or five gallon grow bags, and you should have enough space to accommodate a humidifier.

How do I control cannabis plant height?

By reducing light exposure from 18 to 12 hours each day after the cannabis plant has grown to half of its target height, you may begin blooming your plant.

Do I need a humidifier for my grow tent?

Humidity is essential for producing cannabis and preventing powdery mildew, which can kill your plants if not maintained properly. Allow for additional room (about 126 inches) for a humidifier.

Wie hoch soll eine Growbox sein? Growbox Idealhöhe, gibt es so etwas?

Grow tents are frequently 180 cm in height, which appears to be rather impressive from the outside. If you look a little closer, but just a few inches, you can see the technology and suspension. According to the bulb used, the distance between the lamp and the plants should be 20 to 40 cm, depending on the size of the plant.

What is meant by useful height?

When we talk about usable / effective height, we are referring to the amount of height that is effectively accessible to the plants. Growbox’s total height is less than: – The use of technology (activated carbon filter, fans, pipes, luminaire and suspension) – Pot height– the shortest possible distance between luminaires.

How much usable height does one have in a grow tent with 180 cm height, and how much in an urban Chili grow cabinet?

Grow tent useable height ranges from 29 to 37 inches, with a total height of 71 inches.

The useable height of a grow tent ranges from 75 – 95 cm to 180 cm overall height. urban Chili 2.0’s useful height ranges from 36.6 inches to 52.4 inches in overall height. urban Chili 2.0’s useful height ranges from 93 cm to 133 cm in height overall. Pay a visit to our store.

Your grow tent should be at least 5 feet tall, and it should be capable of supporting up to a 400W grow lamp, however having a bit more headroom makes things a little simpler. For example, if you are 7 feet tall, you will not be restricted by the height of your growing space, and you will be able to install more heavy duty grow lights as a result.

What is a good height for a grow tent?

If you keep them small to medium in size, a 5′ high tent would suffice. Personally, I’d recommend getting a tent that is taller than that, because you can always lower the lights in a 7′ tent if the plants grow too tall, but you can’t raise the top of a 5′ tent if the plants grow too tall. A 4x4x80″ would be my recommendation.

How big of a grow tent do I need for 4 plants?

A rectangular tent shape is the most effective for four plants, and the most typical size is a 44. This provides each plant with around 4 square feet of growth room (or a 22 of the total area). It is really a little less than that, because you want to leave some space between the plants to allow for air circulation. However, this still allows for quite big plants.

What size LED light for 4×4 grow tent?

For the reason why LED lights are typically recommended for grow tents, we will only cover the finest LED grow lights available on the market for your tent. To light a 44 tent, a grow lamp with an actual wattage range of 500-600 watts should be used (assuming blooming plants that demand a lot of light and are collected in a single location).

Can you have too much light in a grow tent?

Despite the fact that too much light can be detrimental to plant development, it is also a rather simple problem to resolve. Experts recommend 100 watts of light for a 2 foot by 2 foot grow area and up to 1,000 watts of light for an 8 foot by 8 foot grow area, depending on the size of the grow area.

How many lights do I need in a 4×8 grow tent?

If the floor is 48, then two 600-watt lights should be plenty for the job. If you are going to use three lights, you may wish to use 400 watt bulbs.

What size LED light do I need for my grow tent?

According to conventional wisdom, you should aim for 32-50 watts per square foot of growing space. If your grow place is a specialized veg tent, you’ll need something closer to 25 watts. Using this example, if you’re dealing with a 3′ by 3′ space, you’d potentially want an LED light with a power demand that ranges between 225 watts (vegetative) to 450 watts (hi-tech) (flowering).

What size light for 5×5 grow tent?

For a 5×5 tent, it is advisable to use lights that are around 1000 watts (High-Pressure Sodium). Although HPS lights appear to be yellow in hue, they actually contain color spectrums that are yellow and red. Plants that bloom well in both spectrums are encouraged to do so.

How many plants can I fit in a 4×8 grow tent?

The approved standard is 8 plants in a 48 configuration.

Does bigger pots mean bigger yield?

When growing in different-sized pots, the larger pot will provide a greater yield. The plant will utilize its two- to three-week stretch to establish roots and determine its maximum size.

How much does it cost to run a 600W LED grow light?

Electricity costs an average of 12.83 cents per kilowatt-hour ($0.1283/kWh) in the United States.

This is the cost per day of running the G8LED 600W Veg/Flower grow light for one year. Calculate the monthly operating cost by multiplying it by 30. Additionally, because of the decreased heat output, less energy is consumed by the HVAC system, resulting in even greater savings.

Do grow tents keep the smell in?

The basic answer to this question is no, grow tents do not have the ability to block off odors. It is possible that the grow tent will have to cover the aroma of your flowering plants before the space can be considered smell-proof. Proper air circulation will assist you in keeping the temperature and odor levels in your grow environment stable and consistent.

What size grow room for 12 plants?

John, A space of 8’8’x8′ can accommodate 12-16 plants comfortably, however it is a little cramped. Because of the varying lighting schedules, you may expect to receive approximately four plants if you want to grow fairly large plants indoors. If you want to grow smaller plants indoors, you can expect to acquire about two plants.

What size LED light for 3×3 grow tent?

In a 3×3 tent, you should aim for 350 watts of power. I would stay away from Amazon’s LED lights. They are either inexpensive and of poor quality, or expensive and of poor quality in some situations. If you’re searching for a light that’s ready to go, 700 is going to be difficult to come by.

How many plants 60×60 grow tent?

9 plants in pots of 4-5 liters each in a 60-60 growtent. 12 plants in 5-liter pots in an 80-by-80-foot growtent. Growing in a 100×100 growtent are 16 plants in 5-7 liter pots.

Does Vegging longer increase yield?

Adding two weeks of vegetative development time can, on average, double your output, according to some estimates. When we reach a pound and a half, this begins to level out (due to the height restrictions in the house). In one month, we get a little plant with good development, thanks to two weeks of rooted time and two weeks of vegetative growth time (a total of four weeks).

Ideally, a huge rectangular base model with dimensions of 96 inches by 48 inches by 78 inches, or 4 by 8 feet in area and 6.5 feet in height, will suffice.

Is 300W LED enough for one plant?

It is recommended that you utilize a **minimum** of 50 watts of light per square foot of grow space while cultivating cannabis, according to a decent rule of thumb.

So 300W can cover around 2*3ft of space, and in general, each cannabis plant you produce requires at least 1 square foot of room. As a result, under 300W, you may grow around 1-6 plants.

New grower – Questions regarding grow tent recommended height.

You are currently using an out-of-date web browser. It is possible that this or other websites will not show correctly. You need either upgrade your browser or switch to another one. Greetings, growers everywhere. I’m a beginner grower, and I’m in the process of purchasing my first grow tent. I’m looking into a Lighthouse 32x32x60h tent for my next camping trip. According to what I’ve heard, there will be a filter and light suspended at the top. I was just wondering if 5 feet in height would be sufficient to allow the plant to reach maturity?

  1. Any suggestions for tents and tent heights for these plants would be highly appreciated.
  2. I’m looking forward to chronicling my very first grow as soon as possible!
  3. Questions regarding the optimal height for a grow tent.
  4. I would only grow one plant at a time because of the size of the tent and the fact that I am a newbie.
  5. When you put too many plants together, they begin to push each other out of the light, resulting in a reduction in the production of each plant.
  6. For every 6 seeds you plant, you may expect either 2 grows yielding 6 ounces or 6 separate grows yielding a total of 18+ ounces, depending on your growing conditions.
  7. Ignore the maximum height that the breeders and dealers claim they will reach and instead train the plant to develop in the manner that you choose.

Right now, I just have one plant growing, which is 23 days into flowering and takes up more than 4 square feet despite the fact that it is only 16 inches tall.

Regarding the new grower.

I much appreciate your comment, and I will definitely take that into consideration.

I’m not in a hurry, but I do want to use a 400w hps/mh, and I’m concerned that the plant will become too tall.

Questions regarding the optimal height for a grow tent.

If you have a few more dollars to spare, it’s always great to have a little additional space just in case.

(LTS, Scrog, Top’n, and Fim’n are just a few examples.) In terms of veg time, it is usually 30 days from the moment of germination.

If you are concerned about your height, this is an excellent approach to employ!

Regarding the new grower.

Yes, I completely think that purchasing a few additional feet for a few dollars is a fantastic idea.

I’ll definitely look at scrog, since I’ve seen it mentioned in a few different posts.

I appreciate all of the advise you have given me regarding this tent dilemma!

Regarding the new grower.

I much appreciate your comment, and I will definitely take that into consideration.

I’m not in a hurry, but I do want to use a 400w hps/mh, and I’m concerned that the plant will become too tall.

I’m merely limited by my height, which is why I’m only able to use the 5 foot tent, which is a shame.

This is my first attempt, so I’m not anticipating tremendous yields or anything; all I’m hope is that I do it right the first time.

Do you have any experience with lemon kush?

We have 60″ of height if we start with a 60″ tall tent, which is what you’re now talking.

They stand between 14 and 17 inches tall.

Then there’s the illumination.

Consequently, we’re down to around 40″ of total height accessible in the tent at this point.

We also have filtration up there, which will be anywhere from 4 to 8 inches in size depending on the tent, so you’re just a little bit above 30 inches available for your plants.

CFLs should not be more than 8″ apart, and I prefer mine to be in the 3″-6″ range, so you should have room for plants to grow to a height of 24″-27″.

In that size tent, a 400w MH would be sufficient (and HPS for Flower).

This leaves you with a plant height range of 12-25 inches accessible.

This leaves you with a planting height of 6-12″ available.

Because you have enough room, you can use any form of lighting you want; all you have to do now is plan it out, do some research, and put out a game plan for how you’re going to train the plant to grow broad rather than tall.

After let them to develop to their full height, I harvested around 1/2 ounce from 2 autos.

I harvested a little over 3 ounces using the same lights, same nutrients, same pots, and even the same soil as I did the first time.

When it comes to lighting expenses, you can get LED panels that are around the same price as a decent CFL system, and the LEDs will outperform CFLs on a day-to-day basis, if not more.

Concentrate solely on producing a high-quality crop, and the yield will follow automatically.

Excellent response, thank you for breaking it down; this 60-inch tent is starting to feel a little small.

A few weeks of vegetative growth would be much appreciated rather than forcing my plant into flowering prematurely due to its little stature.

With regard to the lighting options, would you prefer CFLs over the Hps/MH hood configuration?

Do you have any recommendations?

Regarding the new grower.

Do not be disheartened in this situation, dude!

I’m now growing under LED lights; my plant has been vegged for 11 weeks; it has been flowering for 24 days; and it’s only about 17 inches tall.

When it comes to illumination, HPS/MH will surpass CFLs, but they will require a cool tube hood to keep temperatures under control, as well as an adequate exhaust fan.

LED is my favourite option since it consumes less power than ‘energy saving’ CFL lights on comparable settings and creates less heat than both high pressure sodium and high pressure fluorescent lamps.

If you get a shorter, broader pot, you may immediately gain some more height, making an LED grow entirely feasible.

Introducing Mars Hydro LED – the most advanced lighting solution for horticulture and indoor plants.

With the use of an SCROG, the growing process may be improved even more.

When you can adapt your mix to your specific needs, you may reduce the danger of nutrient poisoning even more.

Allow your imagination to go wild with this one.

Regarding the new grower.

My first concern is safety; anything that doesn’t get too hot would be fine as long as it’s effective and doesn’t cause harm.

Do you have any pictures of the entire setup?

You can accomplish it; all you have to do is train them, as Antics pointed out.

Despite the fact that I am growing in a short/small tent, I train them as documented in my notebook.

I’ll take a measurement tonight, but the distance between the base of my plants and the top of the colas is around 16 inches.

The 400 is around 14 inches from the tops of the colas in my tent, so I have plenty of room left over in my tent.

Allow those plants to run the show, and you’ll find yourself scrambling for space when the time comes.

Re: New grower with questions on the appropriate height for a grow tent.

Essentially, the Qtips are utilized to assist them in growing broader rather than taller?

Correct, I would also require a fan at the bottom of the tent in order to draw in cold air.

I’m just so dang perplexed, haha!

Questions regarding the optimal height for a grow tent.

Taking a look at the Marshydro 100×3 300w LED light.

Is it better to start with two lights or is one light sufficient enough?

What is the effect of LED lighting on the temperature in the tent, and do they require cooling?

Re: New grower with questions on the appropriate height for a grow tent.

My goal was to provide as much light as possible to as many potential bud sites as possible without cutting fan leaves, which serve as energy collectors for me.

LEDs will also allow you to run in a tent that is little shorter.

Perhaps some sort of topping would be most appropriate for you.

We were all at your skill/knowledge level at one point or another (and I’m not that far ahead of you, believe me), but the ones who discovered free knowledge and then utilized it have done the finest job.

Questions regarding the optimal height for a grow tent.

Using passive intake through tent vents at the base, I use a 90cm by 90cm by 180cm tent, a 400w high-pressure sodium 5″ inline fan, and a suitable carbon filter.

I grow in my spare bedroom, where the average base temperature of the house is around 20 degrees Celsius.

On really hot days, I’ve reached temperatures of 26/27 degrees Celsius most of the time.

The exhaust ducting that I just hang over the bedroom door vents out onto the landing area at the very least; it should really be vented to the outdoors.

Questions regarding the optimal height for a grow tent.

Thank you for the advice and information; it is really appreciated.

Keeping the stem and the rest of the plant apart.

The idea of using a 400w Hps/mh light hood was my first thought, but I’m concerned about the heat generated by the bulbs.

In addition, I want to use an oscillating fan to provide a breeze for the plants.

Do you have any experience with LEDs that are fuzzy?

Regarding the new grower.

Strawberry Blue is the variety of plant I’m now raising.

However, there is nothing particularly noteworthy about it.

It’s nothing fancy, and it certainly isn’t as attractive as some of the other grow rooms on this site.

If my recollection serves me well, the 100×3 light (Old Model) will illuminate a region measuring 3’x2.5′ at a height of 24″.

Personally, I would not put more than 2 plants beneath it.

One light is sufficient, but two lights are preferable.

An intake fan is optional, but not necessary if your exhaust fan pushes enough air.

During the seedling period, the light intensity only has to be increased.

With the LEDs turned on, the temperature never rises over 81 degrees with the doors closed and the exhaust turned off.

LEDs have built-in cooling fans and do not require any additional cooling to function properly.

So far, my personal experience has shown that LED is far superior to CFL.

Regarding the new grower.

No.

Mars Hydro LED lighting systems are the most effective solutions for horticulture and indoor plants.

However, if you purchase from them, they will ship from a warehouse that is closer to you, and you will receive a three-year guarantee.

However, the light I’m really purchasing is from their eBay site, and while it’s not as pricey as the one on Amazon, it’s the same light.

It’s impossible not to be them.

I’m thinking of using it for vegetables and adding another for flowers.

Nebula Haze is the author of this piece. Is there an optimum height for the plant towards the end of its life? Most of what I’ve read suggests to keep the plant in the Vegetative Stage until it’s about half the height you want it to be, then switch to the Flowering Stage since plants grow roughly twice as tall as they did in the Vegetative Stage. Assuming, of course, that you are able to maintain the cover as flat as possible. Should you attempt to climb as high as your tent/light will allow you to without burning?

Is it possible that the plant is wasting energy by transporting nutrients up a higher plant?

When it comes to indoor cannabis plant training, the ideal situation is for your plants to be large enough to hold as much bud as your grow light is capable of producing.

As a result, while growing indoors, the ideal length of buds is highly reliant on the amount of light available.

Optimal Plant Height Depends on Your Grow Light. Bigger Lights Can Support Bigger Plants and Longer Buds!

You’ll frequently observe long, fat “colas” at the top of an indoor cannabis plant when it’s time to harvest it, with smaller buds beneath them if you look at the structure of the plant when it’s time to harvest it. It appears like the buds become smaller as you move further down the plant’s stem. After a certain point, the buds become so little that they no longer contribute much to the overall weight of the plant. Large buds grow on the surface, but as you move further away from the light, the buds become smaller and smaller until there are absolutely none left.

  1. Any further time spent in the vegetative stage would very certainly have been considered a waste of time.
  2. Below that point, the plant continued to produce buds, but they were single buds rather than a continuous cola of buds as above.
  3. For a lot of strains, here is where the “sweet spot” is located.
  4. A larger grow light, on the other hand, may have supported a higher plant.

It’s not a big deal if your plant is too tall as long as it fits in your grow space, but the extra lower growth that doesn’t produce buds is an unnecessary drain on your resources in terms of electricity, time, and money, as you could have potentially cut weeks off your vegetative stage without sacrificing yields!

As a result, I’m not sure how much of a benefit you would receive from moving to 12/12 once the plant has grown to 2 feet in height.

These plants were swapped when they were roughly 20′′ tall and were being grown under a 600W light. Greater grow light intensity allows for even higher plants and longer colas to be supported!

Examples with Common Grow Lights

However, while it is true that you should transition your plant to the flowering stage when it has reached approximately half of the final desired height (because it will approximately double in size after the transition to the flowering stage), the following are some general guidelines that have worked well for me: Note: After you’ve finished growing, attempt to perform a “autopsy” on yourself and check through your photos to see if there’s anything you might have done differently to achieve even better outcomes.

Almost every year, I learn something new.

  • T5 and other fluorescent lights should be switched when the plant is 6-12 inches tall (unless you have light coming in from the sides, in which case it can be a little taller as long as all of the bud sites are getting light). Using 250W HPS, turn on the light when the plant is 12′′ tall
  • 400W HPS, turn on the light when the plant is 17′′ tall
  • 600W HPS, turn on the light when the plant is 21′′ tall. Light Emitting Diode (LEC) or Ceramic Metal Halide (CMH) Grow Lights– Follow standard rules for HPS lights according on your wattage (315W is suitable for 15′′ tall plants, and a 630W is ideal for 22′′ tall plants)
  • LED Grow Lights– LED grow lights are becoming increasingly popular. Unfortunately, the model has a significant impact on this. It’s partly a question of trial and error because there isn’t a “standard” for LED grow lights the way there is for other types of grow lights. It’s a good rule of thumb to measure the length of your major colas after switching to 12/12 (from a prior grow) and to try to start blooming with your new plants when they’re approximately that height. So, if your primary colas grow to be roughly 12 inches long, you should begin flowering when the plant is 12 inches tall, and so on. Nonetheless, if you aren’t sure about your LED setup yet, I recommend just adhering to the “half the ultimate intended height” guideline. This assures that at a minimum, the plant will fit in your grow room and that you will be able to understand what to anticipate from your LED model.

Note: Defoliation (removing leaves to expose bud sites) allows you to create larger buds at a deeper level in the plant. Provided you utilize defoliation, your light may be able to support significantly higher plants with longer buds if your light is sufficiently bright. Due to the fact that everyone’s results will be a bit different depending on their strain, environment, and personal growing tactics, it’s critical to always test your plants with your light and your setup.

“Tall” vs “Short” Strains

Despite the fact that plants normally double in height following the changeover, some strains, particularly tall and small ones, might extend more or less than the norm! Always pay attention to what the breeder tells you about your strain and make your decisions based on that information!

  • If you have a “tall” strain, begin flowering earlier than indicated (around one-third the ultimate intended height), and continue blossoming until the end of the season. When using a “short” strain, you should wait until the plant is 34 the ultimate ideal height before switching to ensure that the plant is tall enough when it has finished stretching.

Because the buds at the bottom of the photo are not contributing much weight to the plant, the farmer could have converted to 12/12 earlier without affecting output. Sativa plants of this type can quadruple in height once they reach the blooming stage, which means it’s typical to wind up with a Sativa plant that is far higher than intended!

Optimum Cannabis Height Outdoors?

Outdoor plants, which develop under the intense light of the sun, are subject to different height constraints than inside plants. In the open air, plants can continue to grow in height for as long as they receive sufficient direct sunshine each day and have adequate root area. Root area is more important outside and in soil than it is indoors or in coco or hydroponic systems. Root area for outdoor plants is typically given by large fabric pots (600 gallon containers or larger in some cases!) or by raised beds filled with rich, well-drained soil in a sunny location.

It received more than nine hours of direct sunlight every day.

So What’s theBestPlant Height?

At the end of the day, there is no “proper” or “optimal” height for a cannabis plant, and as with most things in the world of cannabis growing, it is highly dependent on your setup. I’ve provided you with some broad guidelines for what to strive for and what to expect, but it’s important to note that this is a very simplified version of the information. Unfortunately, there isn’t a singular recipe that works for every grower and every situation. However, the images that follow should provide you with some inspiration!

  • Under a 600W grow light, this marijuana plant produced remarkable yields for its size, but take note of how the buds are thick all the way down the stem.
  • In addition, there is open area behind and to the left of the facility, which is useful for parking.
  • In this case, the plant was given a “lollipop” appearance (the lower part of the plant was stripped of leaves and bud sites before being switched to the flowering stage).
  • If this plant had been permitted to preserve additional bud sites, it is likely that it would have produced even more fruit.
  • Please take note of how little the buds are at the base of the following plant.
  • A typical harvest appearance for a properly-sized plant is as follows: the top buds should be roughly twice the height of the bottom buds, with large but little buds at the bottom.
  • Here’s another example of a plant that reached a respectable height at the conclusion of its life.
  • However, you can tell where the buds finish and the thick layer of leaves begins when the thick layer of leaves begins.
  • They could have sustained a plant that was much higher if their grow light had been more powerful in that situation.
  • This plant was grown under a 1000W fluorescent light and has enormous, thick, arm-sized buds that extend almost to the base of the plant.
  • All of those colas would have been far longer, with a large number of hefty buds beneath them.

This plant should have grown around twice the height it was (and double the size of the longest cola) in order to have produced as much as it was capable of under the grow light it was provided. However, the grower still had a substantial amount of bud with which to comfort himself.

What to Remember About Plant Height

  • Prior to flowering, the ideal plant height is about equal to the length of your “main” (solid) colas. For your first few grows, you’ll have to make educated guesses (and I’ve included some tips above to assist you in getting started), but once you’ve gained some expertise with your setup, you’ll be able to dial it in flawlessly every time as long as you conduct thorough strain research first. Plant size and the number of bud sites in the vegetative stage (while maintaining the right height) can enhance the number of colas and, eventually, yields if these factors are addressed. The blooming stage is aided by training the canopy to be flat, yet wide enough to span the full region under the light
  • This ensures that every cola are a reasonable distance from the grow light
  • Allowing plants to grow to heights that exceed the capacity of your lighting can result in lost time during the vegetative period. By exposing more bud sites to light through defoliation, you can encourage the growth of larger buds lower down within the plant. As a reminder, always attempt to perform a “autopsy” after you grow and examine your photographs closely to see if there is anything you might have done differently to achieve even better outcomes! In every stage of my life, I learn something new.

With a better understanding of proper plant size and its relationship to your grow light (as well as how to determine whether you should have let your plants grow taller or shorter after the fact), I’m hoping that some of you will be able to either increase your yields by allowing your plants to reach the proper size, or save time in the vegetative stage by switching to flowering before your plants grow larger than they need to be!

P.S. One Last Thing About Plant Size…

Additionally, the total size and bulk of the plant have a significant impact on eventual yields in addition to its height. A larger plant may easily sustain a greater number of larger colas. As a result, it is preferable to increase the whole plant size rather than only its height in order to optimize yields. Plants that are wide and flat, like a table, rather than tall and narrow, are preferred. Many indoor growers allow their plants to develop in size horizontally while restricting the plants’ capacity to grow in height over the reach of the grow light’s illumination.

You should also teach your plant canopy to be flat and wide before transitioning to the flowering stage, in addition to ensuring that your plants are the right height.

Filling your grow space with colas can help you increase your yields.
