View attachment 16040925x5x 7.5 hmm. thats about the dimensions Im running with a mover at the moment. Im thinking about 16-20 and flip em to flower around 24-30 inches. I had a lot going on at once, hence so many nute totes. At 30+ plants, that area was getting a little crowded. I usually flipped em to flower at about their 4-6th leafset. My light doesnt quite go past 4ft wide, but it can move a 6' path with the 1000w, really well. If you like less plants, youll have to bend em over and lst. I was using about 3/4 a gallon of hydraton for these ladies. It just seemed easier for me to handle penetration, lenght of cycle, height and air movement, to keep em shorter than about 50" at finish. They dont quite double in flower, but sometimes close to it. No worries, the more room you give em, the more theyll take. Number of plants doesnt matter so much as use of lighted area. Id say a minimum of 1 month, or three leafsets before flower. Ive flipped 2" ladies and ended up with a joint. Best of luck to ya!
