When should i move my sprouted seeds under light?

Two of my five Hindu Kush seeds just sprouted today. Looking very healthy i might add. but im not sure when i should put them under my light. any advice plz? thx.

get them under the light as soon as the seed casing is off

If they have sprouted out of soil or rockwool then they should go under the light now, what kind of lighting??

yeah the seed casing is off and it is sprouted from rockwool. the lighting is sun blaster 125 watt cfl. i think its 6500k lumens? someone correct me if im wrong. and thx for the advice guys.

omfg i accidently broke one of the roots of the unsprouted ones OMFG!!! im so pissed... dam is ther any way it will survive? lol... anyways one more question when do u guys think i should start feeding it nutes?

its a 125 watt cfl. but yeah can i save the plant i broke the root? or should i just throw it out? it was really healthy too but when i took a peak inside the rockwool i accidently grabbed it by the seed and ripped the root in two. can it continue growing? pro advice plz

Plant it anyways; can't hurt anything and it might survive.
