i have hydroponic autopot easy to grow 2 gallon modules
Can I move rooted clone plugs directly to 2 gallon pots?
I thought of putting the rooted plugs into 4" rockwool cubes till they grow to the top of the propogation tray then transfer to the 2 gallon modules -please advise. I have a 400watt MH/HPS lamp only.

Did you not have a plan or read ahead ?

YES go right to modules. I guess your using hydrotron, that's good.

I would not go to the 4 inch cubes if not in the right setup they can hold too much water.

MH light for now but keep it pretty far away, you don't want to burn them and light on the nutes.
