What to look for in a grow tent?

Although the sizes of the grow tents may vary, they have similar basic features. Some of the integral ones are: 

Fabric Strength & Density

The durability of a grow tent is obviously very important, it has to be resistant to tears which are dependent on the fabric’s density. The common density of tents is 120-600D, although the greater the better. However, buying the strongest fabric tent is recommended as it keeps odors, noise inside while keeping diseases & spores out. A thick tent also keeps light from leaking in. It should be strong enough to endure stringent weather and spacious to store tools for gardening. 

Quality of the Reflective Material

Different companies tend to offer varying patterns in the reflective materials, however, the best reflective properties are considered to be provided by the diamond-shaped Mylar. If the quality is not given due care and attention, the whole structure can come collapsing down regardless of how well you set up your grow tent.


Effective use of the grow lights is among the key reasons for using a grow tent. The more effectively a tent can keep external light out and grow light in the better. Ideally, there should be complete darkness in the tent without grow lights.

Frame and Pole Strength

Grow tents are constructed out of interlocking poles, some can be adjusted for height. If your plants grow vertically then it is perfect for you. Steel poles are the best bet, as well as ones that can be snapped locked in place.
