We veg in a flood and drain table 3 foot square, using smaller pots (shorter too, to reach the liquid level) then transplant a week before going into the flower room to the final size net baskets. You can use either smaller net baskets and transplant the entire basket (won't be reused) or use a straight sided "solid" pot w/ drain holes and transplant in the normal fashion....the balls hold together pretty well. A four week veg is more than enough if you have good light, three is about right for us using a 600 MH over that tray. They are hitting 20 to 24 inches by flower time. When they flower, they are 6 per 1000 HPS in roughly a 4 foot square area. Doing batches of 18 under 3 1000 HPS lights.I'm just wondering how everyone is vegging their plants to be put in this system. last run went well with noob mistakes i still ended up with just under 3. 8-9 week veg then 8-9 week flower is really putting a damper on things though id like to veg then to 20+ inches.
