I only decided because of two things, one: I had the cash, and two: I don't have the time, I looked at the plant's schedule and the looked at my own family real life schedule and noticed there were holidays coming up and I had a ton of things to spend time on.
I had originally planned to copy your design. I'm going to be asking you questions in the future concerning environmental control concerns. It seems like you had your experience worth there.
i have a 16 plant system as well....
8 on each shelf, 3 shelves, top one is for the 2 week cloning, next one down is half for 0-2 weeks and half for 2-4 weeks
next shelf down is half for 4-6 and other half is for 6-8.
i harvest 4 plants a week as well. i got my light setup so that each shelf is producing 30,000 lumens, all cfl's and tubes. i didnt like using the hps and mh lights so much in my closet that has no exits....no good venting and i dont like having the door open
some people grow for themselves, not really to sell to others. I have got a lil cabinet i bought from Home-Depot. Only 2.5x3x4 feet and i gott a switchable 400w mh/hps ballast in there! only 2 plants, but will make clones. I will say good job, and i wish that i DIDNT have to grow in a cabinet, and that i could grow in the basement...your lucky.
