When growing 12/12 from seed is their an average or general height that a plant would flower to? I'm thinking of creating a grow-op going 12/12 from seed to finish and I'm debating on the height. I imagine it's relative to the strain and flowering period. I figure 3ft should be enough room but I wanted to hear from some with personal experience. For those out who have completed 12/12 from seed grows, is 3ft overkill? Could I get away with 2ft or 2' 5"?
