So ive got 3 seeds that i just germinated in some rapid rooter starter pulgs.
I soaked them in H20 for a day then put them in ht plugs and had them in an incubator for 2-3 days. all 3 are about two inches tall and are just starting to show their second set of real leaves. I have moved the seedlings to a DWc system that just contains tap water, no nutes have been added.

So basically i was wondering when should i start my 400w MH light? I mean would it be ok to start it now and just keep the seedlings 3-4 ft away? Will the light damage them this early if it is that far? Also, do i need to keep the temp up for the seedlings at this point still? with the light on the growroom stays at about 85 F which is just fine, but with it off im afraid it wont be hot enough. Also, do the seedling need a very high humidity at this point? i had been keeping a plastic bag over them to keep the humidity high, but at this point it may just cause more harm than good. And finally, when is it advisable to start adding nutes? I plan to start a low concentration nute soln after the 2nd set of leaves is fully developed. will this be ok??

any help would be greatly appreciated.
