but that just my 2c's

oldtoker said:for clones its not good because sometimes they will try to grow leaf more then a root system and then have lil root system and easily dry up and die. as for seedlings when i start seeds outdoors they are hit by the sun as soon as they pop dirt line so..... id say that they adjust to the intense light producing roots to find the water they need for that enviorment, i have florsent lights and ect but to me its worth 5 dollers to let the plant know what its gona be under. im running a 1000 i put mine on the floor 6 ft away, as soon as they look to stretch at all ill move the light down its kinda overkill for the 1000 to veg ect, but its my situation as my other room is containing males and breeding project. just my thoughts, so anyway id go for it in the room with the big light.
