Thinking of doing a multi strain s.o.g. I know it's usually done with just one strain but I'm in the process of seeing which strains will perform well with thus method. I got 21 clones that are rooted. My flower chamber won't be freed up for another couple of weeks so they are vegging slowly. Should I flower all 21 in 2 liter soda bottles, 21 in 6x6x7 square pots, or 16 in 5 quart pots? I know most of thus is trial and error but just trying to get some input from those with experience in this area. Planning on doing soil in a 3x3 cab under a 400w light. Any advice or input much appreciated!!!!!
