So I'm 4 weeks into flower and have added 165w of cfl for a total of 330w cfl and 128w t8 fluoros, 458w total. 4 ladies in 8 sq ft. I'm having a little trouble with heat build-up even though I have a/c piped in and my closet is not airtight. The only thing I can think of is to add an exhaust fan to the top right hand corner.

I'm kinda torn, because I plan on buying a 400w hps in the next 2-3 months, but I want this crop to be productive. I have a large rubbermaid container for seedlings/clones, a 2x4' closet that is serving as a flower room right now. I also plan on purchasing a tent if I am sure that it will work as advertised. Anyone have any experience with them?

Here are the ladies. What do you think so far?

They've stopped growing so fast now and are getting nice crystals on all the growing buds.
