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.

flow youve got the right idea about keeping the lights a good distance away from your seedlings, let them get used to it,keep a fan going to keep it cool in there

And yes remove all plastic,or anything you used to keep moisture on them

As for nutes its still to early

thanks for the reply
"As for nutes its still to early,your soil should take care of that for now"

im running a deep water culture hydro system. Basically its three bubbling buckets. i have just plain ph balanced tap water in it at the monment.

you have no immediate worry about nutes,

Its someting you need to start gradually with your DWc system and then increse , again like the lights let your plants get used to it

Hey flow just wanted to know if you also cleaned your tap water. Like did you get rid of most of the chlorine,lead and other bad stuff in the water for your plants?

Good luck man...
