Quick one... If someone had both an 8 bulb 42w cfl setup (336w) and a 250w MH setup, what would be better to use to flower with?
mh vs cfl

both.If u plan on using just the mh u should throw a couple of red cfls in with it.

Are the CFLs 2700k? If so, clearly the CFLs. But mixing them together would be best!

Thanks for the responses. It appears that the cfl's are 6800k so it looks like the mh would be the way to go?

ok quick question for the 1000+ post guys in this room For vegging smaller clones maybe 18" tall should I use cfl's , t5's, or 400 watt mh. I have a 400 watt mh actually 2 but both need new bulbs and I have seen a friend have great success with t5's so what I was thinking is keeping the mother/s under the 400 watt and doing the clones under t5's or cfl's. So which should I do for the clones the other 400 watt mh, some t5's,or cfl's.I also have t8's laying around with fixtures if you think that would be better. Thanks in advance.

you can veg the clones under the t5s or cfls.The other 400 can be used for flowering.

It'll make little difference. The lumens are about identical.
You really want 2200k-3000k color temps.... You're going to be dissapointed with MH or daylight CFLs.... They do not flower well. They lack the proper red spectra.

Personally I'd go with the CFL's given the wattage you suggest... but then I;'m a commited CFL grower.. and presently mighty baked on what they can produce
..BUT.... you do need to know how to get the best from them

Yes they lack spectrum and its not ideal for flowering but it can flower none the less.Flowering with mh will have its advantages and disadvantages.Also there are alot of people who just use mh thru the whole life cycle as well as just use hps thru the whole life cycle.

Depending on the T5's(VHO 100 lm/W)... they could stomp MH(80-90 lm/W) watt for watt. CFLs(65-75 lm/W) aren't nearly as efficient. T8's do pretty decent veg too(HO are over 90 lm/W).
