My new stealth box, suggestion?

Well i got a cabinet outside dimensions are 4' tall x 30" wide and 17" deep. I lined it with 1 1/2 insulation. Would it be better to take it off and just paint it white? (give me alot more room for the grow) Also what would be a good setup for intake and exhaust? i keep the cabinet in my shed and its usually 100 in the shed during the day but with fans not im keeping the plants around 85-90 but unfortunately i wont be able to put the 3 fans i have in the box being they are to big. any suggestions on anything else? oh and right now i have 2 2' T5's for light and will be adding a few cfl's

I heard of christmas wrapping paper resembling same properties of mylar. Tlhat would be thinner and free up more space.

im also worried about getting hot spot being my first grow... would that be an issue?

You could go with the paint then. Find the brightest white paint and use that. I believe that would help.

The insulation you have on is gonna create hotspots and keep the heat trapped inside. you are better off painting it white or using reflective material like B/W poly or mylar

Use elastomeric roofing paint... 90% reflectivity

cut a hole in the left side of the box and another one out side proble a bit bigger then a tenis ball and then get some tube and put a fan on one side and and exaust fan on the other pretty easy to do
but makes your set up look obvious if your tryin to hide it..
so u could get another box and put a fan in it and put it next to your other box and pull the side out?

or get a few strong computer fans they can do wonders!
nice and small to :0
