No, ventilation is not fixed. I have been keeping the tent open during lights on and that keeps the temps in the mid to low 70's.
If I close the tent it will easily reach mid 80's. I know this will be an issue with smell and heat when the girls are a little bigger. I have some thoughts but nothing real concrete. Thanks for stoppin' in loudpac.
hmmm, well your house temps are whats determining your tent's temp. If your not willing to get different ventilation or a portable a/c unit ( i know i wasn't) and you haven't tried this already, try lowering your places a/c temp if you can n c what happens. I had this exact same problem with my grow in the beggining and it was 4x26watts in a small PC case, once I lowered my a/c about 3-5 degrees and added a glass barrier temps went down to high 60's at night to low 70's max. Althought its cfl 75 degree air going in can get pretty warm with all those bulbs.
smell is a huge prob, especially since your nose will desensitize itslef in time to the smell and you will not notice your girls stinking the neighborhood up (atleast that was the case with me and i had 1 plant on a micro grow). I know u hate it, but unless it's legal round your way, your going to need a carbon filter or

Your setup n grow look thorough bred, you should be alright in the long run. Im here if u need me.
