Mini Fridge Grow Box

Hey,

Just built a mini fridge grow box.
Here are the stats w/pics:

2' X 1' 6" box
4" inline duct exhaust fan
80mm CPU cooling fan
Fully lined with reflective mylar
4x 100 watt CFL

THE PROBLEM;
Just installed a ACU-RIT temp/humidity clock & its reading 113F with 39%.
Now I don't know if that is true but the reviews on that brand clock have been good.

The only issue I can see is that the holes I drilled in the back are not allowing much air to come in our out. When I put my hand to the exhaust holes I can feel little air coming out & the same to the cooling fan.
I re-drilled the holes larger last night & it still seems to not been helping much.
Wondering if I should just dremel out the whole outline of the exhaust & cooling fan.
Also, should I go down to 65 watt CFL's?

I am a new grower & little of a user. This is mainly a hobby to keep my mind at peace but it seems to be doing the opposite... hah

Oh also, the new growth on the leave tips are yellow on some. Is this because of the heat?

Your fans might be too close together. Also the exhaust fan might be working too hard. Try another hole for ventilation. If that temperature is right then I'm sure your plants are heat stressed.

Nice box though. I'm sure you can make it work.

Thanks!
Yeah, Just trying to figure out the best way.
Don't want to compromise the stealth of the box.

plants are definitely heat stressed. the lowest temp they have even been at is too hot for MJ. you need to exhaust some of that heat better. or take a light out. are they 100w equivalent CFL's or actual 100 watt cfls?

1600 lumen each, so 100 watt equivalent.
At the moment I look the 2 back lights out while they are still seedlings. The temp dropped to 86F.
Once they start to veg (in a few weeks) I'll put the other lights back in.

Any advise is appreciated!

love it....
