My seeds germinated, root riot plugged and they're under a 5w LED light each potted in 1ltr fabric pots,
My main light is 450w, does any one have an idea how far from the seedlings I should hang my main light and when should I switch to my main LED light please,
Doesn't matter I have viparspectrums 600 par.. viparspectrums 1200v...and Mars hydro 1600w..I set them all at 30"then I'll raise to get some growth.. that's the only I'll effect I've have on running then closer..when I first got the 600s I set at like 12-14", straight blue..they just sat there growing huge leaves..I mean it grew big just super short..just takes some runs and you'll figure it out..if it is growing branches more then a inch apart...lower the light or you have the wrong light..well that's how all mine work anyway.
