Nah Spanky. I'm running a 125w CFL now in veg. I also have 5 70w HID - 3 HPS/2 MH - in an array due to my closet dimensions - long and thin. I can grab that CFL barehanded and hold it. It's like holding a cup of tea. But, you know we can't touch that those HIDs at all. Even a regular 60w light bulb will burn your finger tips. Sure, added up, the heat will build with CFLs. But, it will be negligible. Also, with the HIDs you have to factor in the heat from the ballast. The CFLs have built in ballasts. Even then they don't add as much heat. That's really why you can stack up the CFLs so close to the plants. Heat ain't shit with CFLs. LOL
