The heat issue throws a lot of people off, but you have to realize that watts = heat. 2 x 125w CFLs puts off the same amount of heat as a 250w MH. You probably won't notice until summer, or perhaps in a confined spaces, but it's there.
That setup looks tight P. Only advice I can really give is to keep them uber-small.... top early and often. Cut them back while the growth is soft and don't be afraid to hack if it gets crowded under there. I always feel safe with just 3 nodes...... and I trim with extreme prejudice.
Wish I could get you some pics of the damage I do.
Basically once I have taken all the cuts I need, I'll pull the plant out of the 2 gallon pot, and cut the rootball down to the size that would fit into a 4" Kord; then I cut back that foliage to the 3 lowest and healthiest nodes and re-pot back into the 2 gallon. Just sayin'.... don't be afraid to tame them, dig?
