question on seed germination

[op1]

hey ron- hows it goin? have a question on seed germination. looking back on old posts i see you recommend the wet paper towels, then vermiculite tray. my question is this: is the tray on a flood and drain set-up, or is it a flood and stay flooded set-up? also- do you put the vermiculite in the grow rocks, or try to wash off as much as you can before putting in the hydro garden? thanks op
