They would be in my closet which is about 2'x2.5'. Can I also have some tips and tricks on maintaining small plants that can produce a good amount of bud?
General rule of thumb is 100w for your first plant and 50 for any additional, so get more. You want somewhere near 6500k for veg and 2700k for flowering, plan accordingly. Topping and Lst training are your knights in shining armor look into it.
There is no "trick" or tip that will ever produce lots of bud with 2 23 watt CFLs. You need many times more as the above stated.
