What to Look For When Choosing a Grow Tent

Finding the right grow tent for your grow can be a bit of a challenge. Here is what you should keep in mind when choosing a grow tent.

Nine Points to Consider When Choosing a Grow Tent

  • Size – Probably the first thing you need to consider is what size grow tent do you need. Depending on a variety of factors, such as strain, training method, growing techniques and equipment you are using, a fully grown marijuana plant is going to need between 1 – 4 sq.ft. of space. The thing to keep in mind is the size of a plant when mature.      

For example if you are growing 6 plants of a strain that tends to grow large you may want to give 4 sq. ft. per plant. You would need a grow tent that has a combined width and depth of at least 24 sq. ft.. A grow tent 6 feet wide and 4 feet deep.

Here are some example 4 x 4 grow tent layouts for a visual example of how many plants can fit.

  • Height Matters – This is an area many novice growers tend to overlook. You definitely need t consider the height of your plants as they reach maturity. Plus allow space between the top of your plants and the light source.
  • Frame Maximum Weight Rating – Good luck trying to find the weight rating for a grow tent anywhere. If you really want to know you will probably need to contact the manufacturer directly. The closest I have been able to find in terms of weight rating is to look for more cross bars at the top of the tent and to make sure the pole connectors are metal. Vivosun states their tents can carry up to 110 lbs across 3 cross bars.

Generally speaking, any reputable grow tent manufacturer offers tents that can hold lights, exhaust fan, air scrubber, ducts and other common growing equipment. About 100 lbs.

  • Reflectivity – Every grow tent is going to have a reflective interior. You will want to choose a grow tent with a reflectivity rating of at least 96%. The higher the better. In my experience, 98% reflectivity is probably the best available on the market.
  • Material Quality – As I was shopping for a grow tent, it became clear that almost all of the popular brand name tents were made from very similar materials. 600D canvas. This seems to be the standard.
  • Zipper Strength – A heavy duty zipper is preferred. This is something that is hard to evaluate. The more heavy duty the better.
  • No Light Leaks – A quality grow tent is going to have zero light leak. Flaps that cover any zippers and double cinch ventilation socks are features to look for. Once you have your tent, you will have to check for light leaks manually.
  • Metal Poles & Connectors – Thicker metal poles and bear more weight and metal connectors improve overall stability and tent life. Some lower quality grow tents have plastic pole connectors. You want metal connectors.
  • Price – Across different grow tent brands prices seem to be pretty consistent. For example a 48″ x 48″ x 80″ grow tent is about $110.00 across a variety of manufacturers.

Choosing a Grow Tent Summary

From our own research, grow tents are pretty standardized across different brands. Probably the biggest differences are in pole diameter and reflectivity.

For my growing needs, I went with VivoSun Grow Tents. Thick steel pole diameter and 98% reflectivity.
