Is the time right to transplant

Right thanx for all the comments on my posts , now decided to go with soil my dilema is now. My cuttings have been rooting for 10 days now they seem to be doing very well so am thinking off putting them in the pots will soil and starting to use my 600w light. will my young plant be ok handling it , the light there under is weak and my grow room is cold so am hoping the interducing the 600w light will combat this problem , also when should i first interduce nutriants to my plants.

You say your cuttings have been rooting for 10 days, does this mean they actually formed roots, or just that they've been trying to for the last 10 days? If they have roots than go ahead and transplant them into soil and move them under the 600w. For the first couple days keep the light fairly high, like 4 feet or so away.

Have you tested your 600w to see if the temps are okay with it on?

As for nutrients it really depends on what you are using and what soil or soil mix they are in.
