i earlier started a post asking about sun leaves and was redirected to the litature on the site and it does make sense to me but i ve been doing this along time and tried both ways with equall results so this time around i have did a experiment i have 18 plants under 3000 wattts hps the first six i trimmed tons off sun leaves right before i put into bud the second set of 6 i trimmed half as much sun leaves and took all ther bottoms off and the third set of 6 i left all natural i am now in 4 th week of bud and they are all looking pretty equal
