have 10 master kush seeds just pooped thru rockwool 2 days ago plants 2 inches tall i have them in plastic dish under 400w hps (plan to add another 600w) soon but question is can i move these seeds to sysem now and if so how many times a day should i flood seems rockwool gets soaked with just pour a little water in dish so im worried about over watering

2-3 times a day should work fine. Depends on What size rockwall is being used. Morning night a maybe mid day.

Twice a day until you see roots coming out of the bottom of your big pots. Three or four times a day after that.

I personally use this system and i water once every three days imho the best way is just feel your rockwool if its dry flood em if not wait when i 1st started using this system i was watering 4 times a day long story short they almost died the rockwool has to dry out b4 u water again this is my technique and my shits blowin up!!!!!
