I did some more work on the cabinet today. Solid side walls instead of mylar. Plus I drilled all the holes and put in some tie rings, etc for Sea of Green or whatever... I also attached the exhaust fan to a section of the vent tubing and then to the light globe/candle surround. It is working well and keeping the area cool. I need to find the flex vent tomorrow in the correct size and I will vent it out the top. (so it will be ready for a carbon canister on top) I also will mount the front top board where the curtain will hang from. It will have velcro to seal it shut...
