The Best 3x3 Grow Tent Review 2020

Vivosun Mylar Hydroponic Grow Tent - Best Overall

Vivosun earns its worldwide reputation for manufacturing high-quality hydroponics equipment. And The Vivosun 3x3 Mylar Hydroponic is one of the best-selling grow tents on the market that you should consider first.

The tent is made of the first-rate 600D fabric, featuring exceptional tearproof and lightproof advantages. In addition, 98% of the interior is made of mylar - a highly reflective material. The long-lasting frame of the tent is also well supported by the strong steel poles. Compared to poles made of plastic, these are far more long-lasting and compact.

To prevent the interior light from escaping, this Vivosun model is equipped with heavy-duty zippers with double-stitched seams. Therefore, the overall tent design does a great job of reflecting the light to escape out of the tent, enhancing the yield efficiency.

However, some users complain that the tent appears to have pinholes in the fabric. On the bright side, if you happen to find some on yours, you can ask for the warranty.

Pros
  • Long-lasting construction with 600D canvas and compact poles
  • Tearproof and lightproof
  • Reflective interior with mylar material
  • Heavy-duty zippers
  • Nice ventilation system
  • Convenient observation window
  • Removable floor tray

Another outstanding 3x3 grow tent on the market is the Gorilla GGT33, manufactured by the leading hydroponic equipment brand Gorilla.

The ventilation system of this Gorilla model can live up to every users' expectation. It features ducts and mesh vents, which help enhance airflow effectively. Moreover, the tent comes with a variety of ports to let users manage essential gear.

Another excellent feature of this tent is the steel frame. It employs 1680D fabric steel, which can stay good as new for years of use. Like other grow tents, the Gorilla model has zippers with full wrap around to ensure the best light reflectivity
