Can I grow 3 plants in a 2x2 foot 5 foot tent …?
That space is really good for only one plant. It would be very hard to control plants to remain small enough to grow all the way out in a space that small.
It depends. I’m growing in a 2x2x4 and I just did 3 Northern Lights autos at the same time. Never again, way to cramped. I previously did 2 Blue Cheese autos and those were do-able. One photo, lst’ed and topped - probably. It will boil down to the strain you try and how it grows.
