Hey guys, Im running a 5x10 tent with a 4x8 flood table. Running 2xCLW 550's , 1 CLW 440 and 1 CLW 220. Using advanced nutrients whole line up. Pro Mix HP, 5 gallon pots. 10 plants. x4 humbolt Chocolate Mint OG x3 DNA SkyWalker OG x3 DNA L.A Chocolat I just purchased a grozone CO2R controller, 20lb tank. I have not bought a regulator yet, ive heard some horror stories about the titan regulators. so I need advise on what regulator I should use. I have never used c02, so this is a learning curve for me. Where do I hang my c02 controller, plant height? not sure on this? im wondering if I should be buying a c02 rain kit? Also, if a regulator/ controller malfunctions and drains my whole tank, could this harm us in our house? Our grow room in the bedroom right next to ours. any advice or pointers would be a lot of help. ive attached some photos so you guys know what i'm working with.
