Variety is the spice of life. I don’t prefer a certain strain, sati, hyb, Ind. it’s all good. Only ones I won’t touch are the headband strain and the derivatives of it. Don’t like the temple squeeze feel it gave me… and nope, no difficulty feeding. I keep a hard copy journal of strains and notes are pretty accurate. Plus, most are the same age. Usually 2 plants per cultivar, so if I fit say 6 in the 4x4 it’ll be 2 each, 3 cultivars. So 3 “different” feeds. And the other tent with photos are about the same age, so that tent will get all the same. I only use Megacrop for salt fert and Dr earth for dry. Mixed in and top dressed.
