Here's a picture of two plants about 3 weeks into veggy mode. The one on the left is a bit skinny and is crying out for transplant into a larger pot. The other is doing well and I plan on letting her grow all she wants as long as she continues to stay bushy, she is only 10" tall. Am I wrong at wanting to wait on her till maybe 2-3-4 feet before going to flowering? They were grown under 160 watts of gro-lux growlights and given no fert other then what was in the starter potting soil.
The fixtures were $9.00 ea they hold 2 -4 foot bulbs @ 40 watts and the bulbs were $6.00 each. You can get higher output fixtures but it really doesn't matter cause of the limitations of the bulbs wattage.
