After 4 years of growing and poring over RIU posts and stickies, I think I finally have a pretty good little grow, operative word little. Just 3 plants but that's plenty for me. It's been an all organic grow in soil, all organic nutes. Using a Growlab tent with about 900 HPS. In previous years I had to pull the plants out too early because of heat, but this year I bought a small portable a/c unit with a thermostat and it's working like gangbusters. Keeps a perfect temp all
