yeah you can do 14 plants, i just went to flowering today, from 3 weeks of vegging. be carefull of the seeds that you want to grow in it, aurora indica is the plants that will do excellent in it. but something like big bud x 14 plants will be way to much, you see what 1 big bud plant would look like. my grow space on that one was 3x4x6 and she was cramped, imagine 14 plants.
