I personally do it a different way. I have moms in dwc and I take 6-8" clones. Once they establish a good roots I go straight to 12/12 with no veg time 2 liter bottles using vermiculite and perlite aka hempy method. 4 plants per sq ft. Under a 600 watt light you can do 30-50 plants. Avg plants 10-15 grams dry......do the math..you'll have plenty of smoke.... That's a true sog ( no veg time)
