i was talking to someone about their grow chamber and they can only grow their plants 24 inches tall and they say they can pull more or less 2oz per plant. is this possible? even with a medium - high yielding strain? and also would you produce more bud with a chamber taller than it is wider or the other way around? for example which would pull more bud out of these two diff dimensions in your opinion. both are going to hold 10-14 plants under a 400 watt hps. i have these areas available in 2 diff locations and need to know which would be best. 24 inch high grow space, 48 inch wide, 30 inch deep. or 32 inch high grow space, 30 inch wide, 20 inch deep.
