Need Help W/ Clones Fast

I have 14 plants under 1000W MH's right now, 5 seedlings under CFL's, and I just started 10 clones in a Rapid Rooter. Today my friend gave me 2 clones that hes been growing but had to get out of his house. His clones are about 18" - 24" tall and have been in a closet under a HPS for about 2-3 weeks and have NOT began to flower. What should I do w/ them? My plants arent gonna be ready for the HPS for another 2-3 weeks and his clones are way to big for the R.R. Can I put them under the MH's w/ the rest of my plants and then back to the HPS when the rest of my plants are ready or would that hurt them? Or should I just cut up his clones into smaller pieces & start them over in the R.R. w/ my other ones? Thanx.

personally, I'd stick them under the MH, and maybe try to get a clone or two off of them before you stick them in 12/12

oh ya you can switch from mh to hps all day long.
whats more important is the amount of time the light was left on.

but ye if they get too tall for 12/12 you can always train them or tie them down.

mh is perfect for veg
put em under that

Thanx for the help guys. I havent been able to get online sinse I posted the question & couldnt see your responses so I put them under the MH till I got back on here. It seemed like the obvious thing to do but I wasnt sure if goin from a HPS to a MH and then back to a HPS in a few weeks would confuse the plant. I have another question too. Im gonna be posting another question on the web site so if any of you could somehow follow it Id really appreciate any feedback on another subject. Ill try to post a link to it after I write it, if I can. Thanx again.
