thanks for the snappy replies. the plant i refer to was started in a rockwool cube. i know, extra lame. i ordered more rapid rooters though! the rock wool cube was then placed into hydroton when rooted well. big stress was caused to it as a clone from my friend who put it into flower 3 days after taking the cutting! here's a week old pic...

since that pic was taken, i've had it in flower for about 6 days now and it is doing well. currently i flood 6x/day for 5 minutes. would longer flooding increase growth rate?
