A Buyer’s Guide to Grow Tents


The right Grow Tent plays a vital role in the growth of your plants. Most newbies into the world of growing are often confused about which grow tent to buy and sometimes make the mistake of buying the wrong one. Yes, a grow tent can be wrong! Quality plays an important role when selecting a grow tent, the price and the usability comes next. There is a vast variety of grow tents available online, but unless you are sure of what are you getting, don’t invest. Here’s a guide to buying the grow tent that will help you yield the wonderful results you desire!


Size Matters!


Most people consider the size as the last priority but ask the experts and they’ll tell you how size is the very first thing that matters! First decide where exactly you want to put up your grow tent. This process includes making sure there are power outlets nearby! Then measure the exact area- length, breadth and height- of the place. In case of a pitched ceiling you will need to measure from the lowest point before you can select the right tent size. Ensure you have the exact measurement. When looking for a grow tent these measurements must be referred to, down to the last bit! So now you know the approximate size of the tent that’ll fit well in the area you have selected. If the area is very large plan and analyze the amount of space, you are going to be using for growing.


No Compromise on Quality!


Quality is prime! A cheaper grow tent may seem like a steal deal but you may end up having a disaster right in the middle of your growing process! Do not compromise when it comes to the quality of your grow tent. There are varying quality levels, depending on different brands; choose the best of the quality, especially if you are planning to continue growing for a long time to come. If you don’t want to invest too much go for the next best but never go for the cheapest quality, not even for one time growing! Let’s take a deeper look at quality levels:


  • Economy Grow Tents:

Economy grow tents are a good choice in case you don’t want to spend too much on the tent. Depending on the brand, sometimes economy line may be short in height or the fabric may be too thin. They might have a lesser weight support or smaller/lesser ducts and power ports. The features they offer are lesser than the high end tent lines but again, if you know the brand and you are sure about the amount of money you are willing to spend- go ahead!


  • Mid Grade Grow Tents:

This is always a balanced decision- a bit of both sides! The quality is much better as compared to the economy line and so are the features and other aspects, while the price is lesser than a high end line tent. The variety in this range is higher than the economy grade and you can make a selection from a larger pool of products available for you. Whether you are a newbie or a seasoned grower, mid grade grow tents are highly suitable for all.

  • Premium Grow Tents:

The name says it all! Premium grade is premium in quality and offers the best of support and features, enabling and enhancing the growing experience at every level. You can be absolutely sure of the product and choose from a wide range of grow tents available in this grade. It’s definitely the best option but yes you also pay a much higher price for it.


So, that sums up the Grow Tent. Now that you know the size and the quality you are going in for it’s time to take the next step- Grow lighting.


There are a number of grow lighting types and you can choose the most suitable depending on various aspects. For more information on grow lighting types and how to select the best for your specific need refer to our Comprehensive Guide to Grow Lights.


To give you a start, we recommend some basic HID lighting and the right wattage to use based upon whether you are using open reflectors or air cooled ones. The lighting and the wattage is selected based upon the size of the tent. Look at the list below to get a better understanding:


Tent Size to Lighting Wattage


2'x2' -- 250W (air cooled), 150W (open)

2'x4' -- 400W (air cooled), 250W (open)

3'x3’ -- 400W (air cooled), 250W (open)

3'x5’ -- 600W (air cooled), 400W (open)

4'x4’ -- 600W (air cooled), 400W (open)

5'x5’ -- 1000W (air cooled), 600W (open)

4'x8’ -- 2x600W (air cooled), 2x400W (open)

5'x10’ -- 2x1000W (air cooled), 2x600W (open)

8'x8’ -- 4x600W (air cooled), 4x400W (open)

10'x10' -- 4x1000W (air cooled), 4x600W (open)

8'x16' -- 8x600W (air cooled), 8x400W (open)

10'x20' -- 8x1000W (air cooled), 8x600W (open)



You have the right tent and you have the right lighting, next up is – Grow Tent Ventilation. Ventilation is essential and has a direct impact on the growth and results you achieve. Proper air circulation and ventilation are absolute mandates to get good growth results. These stabilize the growing environment and enhance the growth. Without air circulation, even if it’s not too hot, the humidity level can increase, damaging the growth as well as the tent and lead to mildew and mold. You definitely don’t want that happening!


According to the size of the tent, minimum ventilation must be ensured. We are just focusing on the air circulation requirements here and not including the cfm requirements for cooling lights or powering carbon filters. Below is a list that gives proper ventilation recommendation based on the minimum requirement for ventilation according to the size of the tent. The open reflectors recommendation is based upon air exchange for every 30 seconds where as it’s for 1 minute in the case of air cooled reflectors. Open reflectors emit greater hot air and thus the difference.


Tent Size to Ventilation Requirement


2'x2’ -- 21 cfm (air cooled), 45 cfm (open)

2'x4' -- 45 cfm (air cooled), 86 cfm (open)

3'x3’ -- 54 cfm (air cooled), 107 cfm (open)

3'x5’ -- 95 cfm (air cooled), 192 cfm (open)

4'x4’ -- 104 cfm (air cooled), 204 cfm (open)

5'x5’ -- 160 cfm (air cooled), 319 cfm (open)

4'x8’ -- 204 cfm (air cooled), 408 cfm (open)

5'x10’ -- 319 cfm (air cooled), 638 cfm (open)

8'x8’ -- 408 cfm (air cooled), 815 cfm (open)

10'x10’ -- 638 cfm (air cooled), 1275 cfm (open)

8'x16’ -- 815 cfm (air cooled). 1629 cfm (open)

10'x20’ -- 1275 cfm (air cooled), 2549 cfm (open)


We are one step away from completing the basic guide. The final step to take note is- Grow Light Cooling.

If you are planning on a multi lights setup, we would recommend using approximately 100cfm per fixture for perfect air cooling. Simply, a 6 light room needs minimum 600 cfm. For a single grow light tent you could use the smallest 6” inline fan or also opt for a 4”. Most air cooled reflectors only go down to 6”. If you are also planning on connecting a carbon filter, don’t forget to add the extra 100 cfm while choosing the right fan.
