Our 8 x 4 Grow Tents will easily house 12-16 medium to large plants, or many more if you want to keep them smaller. This size indoor grow room is a popular size due to it not requiring an entire room to fit in. We recommend the 4x8 portable grow room to have two 600 - 1000 watt grow lights (or equivalent) to cover the entire footprint of this tent. Using a plant growing tent allows you to better manage the growing environment, maintains a clean garden free of outside pests and contaminants. The quick and painless set-up and take down makes these grow room great for renters.
