Hi, I'm thinking of doing a grow with subcools super soil, using a 3 x 1.5 x 2m tent and 20ltr airpots. I'll use 2 1000w lights with 6" cool tubes. I was wondering how many plants I should do without overcrowding? and if I veg for 2 weeks in 6ltr pots then transplant into 20ltr airpots half full...
