    Sorry if this has been asked before, I found it hard trying to word my google searches. Any who, I have two cool little sprouts in two starter plugs..they still have their little helmets on, and one is a day behind the other. I was curious how long I should leave my lights on them at this stage, 24/7 or will that surely kill them.

    Update: One lost it's helmet and showed it's first two leaves :D

    in veg, you can go a couple of ways. 24/7, 18/6, or 16/8 which i use. there are a number of schedules people use, but these are the main 3, imo.

    Thanks for the quick reply. 24/7 seems to be the easiest of them but might not be the best idea.

    Is it common for a freshly sprouted to have some browning on its "first two leaves" or am I burning it already.

    well, if you're giving a fresh sprout nutes already, you can count on burning.

    I always use 4/20

    No I using purely water until they're old enough to need nutes.

    I prefer 24/0 in veg. There no reason not too other than trying to save on the power bill.

    18/6 is best and the natural way
