ok. i put all of the fans in the top blow-hole style, after flipping the box upside down and using the previous fan holes as intakes and covered what was the top hole and cut the new intake in the back of the box. if it sounds confusing i will post pics.

i've seen it get back up to 88 i think. right now ambient is ~79/80 and the box is running at 83.9. i've also set up a floor fan blowing in one of the intakes at the bottom.

i think part of the problem is the styrofoam that i'm using as a shelf. i did this to keep the plants close enough to the lights. it's blocking airflow i know, but it does have holes in it. i'm trying to find a better shelf that won't block as much airflow or lower the lights. i think i got it down to 82 and some change last night without anything in the box. i know it's not but about 5 degrees above ambient, but i'd still like to get it to cool off more if possible.

pic 1 - the top part of the shelf. the long hole face towards the back of the box.

pic 2 - inside of box, you can see the styrofoam shelf and intake on the right side. there is a 6500K bulb hiding behind that 2700K bulb.

pic 3 - top of the box, exhaust.

pic 4 - top view of shelf as looking into box.

pic 5 - what the shelf looks like inside the box a little closer to eye level.

should i make some reflectors for the lights? just trying to make it as optimum as can be with what i'm working with, ya know? thanks for the advice. keep it coming.
