Here is the grow info.
12 plants (max allowed in my area for meds) under the mainframe in a 3 x 4 array. You could also go with 6 larger plants. I use 7 inch square buckets placed in a 2 x 3 cement mixing tub from Home Depot.
I grow in CoCo and hand water since it very forgiving of screwups and I don't have to worry about equipment failure. I can't say enough good things about CoCo.
I don't use a scrog net since I like to be able to move individual plants for maintenance, trimming and more important being able to place them for optimal lighting as the grow larger.
The buckets have slots on the sides making it very easy to train the plants and keep them low using wire ties. I train them in a circle around the perimeter of the bucket. If I go with larger plants, I use a wood trellis (pics somewhere on this forum).
