It's going to be really difficult to achieve full potential with your newly aquired plants. They are definitely budding females... so that's a plus :thumbsup:

Ideally, each of those plants would normally require their own pot. Did you pull them out of the ground and place them into the container... or were they already in it and growing outdoors? Since they are fully flowering you probably can't seperate them without severely damaging the roots. If anything, I would suggest you at least weed the pots. No need for unnecessary vegetation in the already limited soil space. If you are going to complete the life cycle indoors... you will need to make a serious attempt at providing an adequate grow environment (light/dark/food/ventilation, etc.). You won't be able to just leave it under a bedroom incandescent and water it if you expect anything more than what's already there... and possibly not even that.
I would suggest you keep them outdoors to provide the appropriate light and schedule. Possibly getting some food for them... but that's a pretty tricky situation you got there. I'd wait for others to comment. Maybe they have some sweet surgical techniques to get those babies apart... or inform you that they have about 4 days to live :hippy:
Good luck :stoned:
