thanks for the advice Doc. Im going to go with a 600 watters instead of 400's, so it will be 2 600 watt digital ballast with both mh and hps.the clones are already coming in 1 inch rockwool cubes, so im guessing you could pack quite a bit on 3'x3' table. Im gonna stick with 20 on each table i think.
As the whole process gets going and goes smoothly im gonna to be putting clones in at different times so that every week or 10 days i can have a harvest of some bud, whatever the amount.
