Grow Room Info Inquery

Welcome to the forum. You only need two rooms. One for flowering and one for mothers and clones. With that kind of space you may want to seperate mothers and clones as well. Keep in mind you will need room to move around your plants. You would want to start with the physical plant first. Electrial, plumbing, drain and air handling should be planned first. You might want to check out Al B Fucts thread "How to get a harvest every two weeks". Kinda lays out the plan. VV
