Best Ive ever done in a 4 x 4 area, and a 1000w HID with Hortilux Bulb, from 1 plant was 22oz. I vegged it in 5 gallons of Promix BX for 60 days, and transplanted it into 20 Gallons of Promix BX, and vegged it another week, and then flipped the light. The only training I did was to bend the plant over at an early age, and all the side branching turned into main shoots.
The strain was a 2010 Barneys Farm G13 x Haze, and this strain will also stretch 3-5 times its size after flip to 12/12. It took up the whole 4 x 4 area. It looked like a forsythia bush.
We still have the mother plant.
