sorry, also never trim clones, and you wont have if you follow guidlines buddy. Also leave in wool when planting. But ensure you water them like you would rockwool (not much) when you first plant. i.e if you put clone in perlite you wouldnt water 4 times per day for 15min as you would with perlite. Under HPS or MH the moisture will go quicker so if you water only once per week they will die. Less is best, you can increase water slowly, but to much to early will kill them then its to late to go back.
