I too would only go with one per bucket. If you want a big harvest you need a big root ball. Why pick out the smallest one when they could be female. If they are females you remove only to keep a males then your wasting your time and money.

In time, they will root bound that container then you'll be posting my plants are dying please help me.

When I was doing indoor I would plant one per bucket after germination then no need for later transplanting. 5 or 8 per bucket is like 15 Mexicans living a 3 bedroom rambler. You feeling me? But what do I know?
