Grow tents come in sizes ranging from 2’ x 2’ all the way up to 10’ x 20’, so how do you know what size or type is right for you?
We'll show you how to pick the right grow tent to fit your needs. 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 a tent for vegging, a tent for flowering and possibly even a tent for harvest, curing, and drying. It doesn't matter if this is your first time or this is your 100th time, there is a tent for you.
How big of a grow tent do I need?
The first thing to decide is where you want to grow. If you are growing in a closet then you'll want to measure the inside dimensions and choose a tent that will fit.
It is also important to decide how tall you want plants to get as well as the height limitations of your growing space. Tents come in heights ranging from 4' to 7' with Gorilla Grow Tents allowing taller grows with additional tent extensions.
If this is your first grow, try to pick a tent that will allow you space to work inside and start with a moderate number and size of plants. Take notes and really get a feel for gardening. You are going to learn a ton of things that will vastly improve your next grow.
If this isn't your first time you probably already have a good idea of what you are looking for and the unique challenges you are already facing. With that in mind, here are some unique features of tent brands.
Consider a standard 5'x5' High Rise Grow Tent (formally Hydrobuilder Grow Tent). You can grow anywhere from 2 extra large plants up to 16 small plants (see figure 1).
If you are growing very small plants such as herbs or seedlings you can have several layers of plants on rigid wire shelves in order to maximize vertical space inside the tent. Shelves are also useful when it comes time to dry your crop.
There are a number of removable suspended mesh drying racks that will fit inside your tent in order to utilize the tent for the entire growing cycle. The mesh allows for even drying conditions. Many of these collapse down for ease of storage when drying is finished.
Grow tent equipment
Another important consideration when deciding what size of grow tent you need is how much light, nutrients, water, and ventilation equipment will be needed for each of these setups.
By multiplying height by width by length you will get the cubic volume of your tent. It is best to exchange this volume of air every 1-3 minutes.
For more information on grow tent ventilation, check out this full guide.
For the above example, the tent is 5 x 5 x 7 or 175 cubic feet. This means that you need a fan that can move between 60 and 175 cubic feet of air per minute (CFM). Bring fresh cool air in from the bottom of the tent and exhaust warm air out the top.
The best advice is to start with a tent that is slightly larger than you are needing initially so that you have some room to grow (pun intended) and space to work around your plants inside.
There’s nothing worse than going through a cycle and finding out that if you want to expand you are going to need a larger tent, larger lights, etc.
Plus, having some extra room inside the tent can be very handy for being able to more closely observe your plants to ensure their health.
Tent wall thickness also plays a part in which tents you want to consider. If your tent is in an indoor location you may not need as thick or rugged of walls as opposed to an outbuilding or shed. Tent thickness varies from 1680D canvas thread count on down to 210D (the D in those measurements stands for denier and is a measure of the linear mass density of fibers) (Haynes, p. 217).
Some tents, such Gorilla grow tents, also support height adjustment. This allows you to add additional vertical feet to a tent and increase yield (see figure 2). Gorilla Grow Tents are the first ever height adjusting grow tent. Grow plants up to a foot taller (or more with additional extensions) and yield up to 33% more! Gorilla Grow Tents are one of the most popular grow tent brands on the market today.
Manufacturer Secret Jardin offers tents that have a separate chamber inside of the tent to support isolated bloom and grow cycles within the same tent.
