I know a lot about carpentry a bit about electrician work and the combo makes me love to do shit on my own. i built my grow chamber out of the foam board because i had it around, other wise i would have built a grow room myself with 4 pieces of plywood for 48 dollars if from home depot, or maybe even cheaper if i get it from the local lumber yard. i wired the hps myself, and made an aluminum reflector. damn that shit gets hot. im firing up my grow in the next couple weeks. I hope it goes okay because i have to leave my brother to tend to the grow for a week. but hey its an experiment. haha

No problem glad to help. The plexi glass heat barrier is a simple concept and serves two purposes. If you cut a strip of plexi glass and leave 2 inches for air to pass, well heat rises. Your creating an "attic" like effect. Hot air rises, its traped in the uppermost compartment, while the cooler air is trapped in the bottom. The light still obviously penetrates and serves its purpose.

Now that you have an attic, you need to vent it but hey now. That attic is alot smaller than the rest of the cabinet.... so... you can get away with less cfm to cool because your not cooling the ENTIRE cabinet, only a smaller section of it. And the two inch slit allows the cool air up and out.

Good luck with your grows man. Hopefully your bro has a green thumb. Glad to help

Ill post a pretty pic from my closet grow just cause :jointsmile:
