How big of a grow tent do I need?

Be sure to carefully measure the length, width and height of the space you intend to set up the grow tent in. The tent should be slightly smaller than the space to allow for easy setup and maintenance. You will also need to consider what your gardening goals are, and what size tent will allow you to achieve them.

The real question you need to be asking is how many plants do you want to grow and how big do you want those plants to be?

The size of your plants greatly effects what tents you want to be looking at. Another consideration is if you want to start continuous harvesting or if you want to grow in distinct cycles. Usually, continuous harvesters will often want one tent for vegging, another tent for flowering and possibly even a third tent for harvest curing and drying

Because plant strains and container sizes vary, the number of plants you can grow in each size of tent is subjective. Some growers like to grow a larger number of smaller plants and harvest them more frequently, auto-flowering strains are good for this. Others like to have a couple of plants and train them to grow very wide, this is known as the SCROG method.

Finally, others want to grow the largest plants possible and will have a smaller number of large plants.

Therefore our recommendations on plant counts for each size of marijuana grow tents are just that, a recommendation. Your actual plant count may vary.

Here is a quick guide to sizing your tent with how many plants you can grow:

• 2' x 2' Grow Tent - Great for mother plants (1-2 plants)


• 2' x 4' Grow Tent - Fits in most closets (2-4 plants)


• 3' x 3' Grow Tent - Ideal for people with a limited work area (2-4 plants)


• 4' x 4' Grow Tent - Perfect for the footprint of a 1000w HID or LED grow light (4-6 plants)


• 5' x 5' and 4’ x 8’ Grow Tents - Our most popular tent sizes (4-10 plants)


• 5’ x 9’ and 8' x 8' Grow Tent - Great for a spare bedroom, expect large harvests (9-16 plants)


• 10' x 10' Grow Tent - Another perfect size for a spare bedroom or in the garage. (12-18 plants)


• 8’ x 16’ and Larger Grow Tents - Requires large space and power amperage for lights (16-32 plants)

1. The size of the tent you choose is one of the most important decisions you’ll make. Together with your plant choices, it will inform your selection of supporting components and contribute to your overall operating costs.


2. If you choose an oversized tent, you run the risk of paying more for your basic equipment and for the energy necessary to power your lights, fans and other equipment. If you choose an undersized tent, you risk creating a crowded and potentially unhealthy environment for your plants, or one that simply won’t accommodate mature plants, even after aggressive staking or trellising and pruning.


3. Even though grow tents are available in lots of different shapes and sizes, the one thing they all have in common is their basic purpose — to contain and cultivate plants. You can find tabletop models, and tents that fit into walk-in or sliding-door closets.


4. There are tents large enough to dwarf a basement or attic, but fill a suburban garage. Square and rectangular tents are both popular, and you can find ones with low, high or adjustable-height ceilings. With all these options, how do you choose?


5. What goes on inside the tent will help determine the right size for your needs. For example, if you plan to get a jump start on outdoor spring planting by cultivating seedlings, you may be able to get by with a small, low tent. Seedlings wouldn’t necessarily need a roomy ceiling height, but they probably need adjustable lighting designed to enhance vegetative growth.


6. In tent selection, form follows function, and function is usually linked to the number and type of plants involved. Manufacturers aren’t always specific about how many plants can be cultivated using a particular best indoor grow tent. There’s a reason for that. What you grow and how you plan your garden project, down to the containers or hydro system you use, will have an impact on the number of plants your grow tent can support.

If you are a home grower, a  4x4 grow tent is best recommend, which can meet your needs and also cover a suitable place.
