what to do with my clones

okay im going to get 20 clones and i think im going to get them at 10 days old will they all die if i put them under my 400w light or should i put them under a florecent light and if so for how long and how many wat light cuz i have 1 4ft floresent light with 2 40w bulbs brand new..need advice

you can put them under 400 just be careful of the heat

what should i keep the temp under or shold i not risk it and just use the floresent light for a little bit.i dont know much of caring for clones so as much advice i can get wil be very appreciated

If they are well rooted then the 400w will be fine if not keep them under the florescent a little longer.
