I run pretty much single unit bubblers. I have plants in all different stages of growth. Buckets are raised or lowered to maintain an even canopy and plants in different stages of growth or different strains are given different nute strengths. These Satori doubled in height from the time I put them into flower until now. Actually, the second one a little more than doubled and is still stretching some. Satori are a little nute sensitive, but they are very forgiving, as is Speed Queen. I never run my ppms over 1000 with my Mandala strains.
I currently have 3 Satori, 1 Safari Mix, 1 Speed Queen, and 1 Durban Poison x Skunk1 in flower. I find I do best with a max of 6-8 girls flowering at a time in the space I have.
