Thoughts for a new grower?

I have a mini fridge that the freezer busted on so I turn it into a growbox so I can sell it. Pretty restricted on money.

Approx Inside Dimensions:
Length: 1.5 feet
Width: 1.375 feet
Height: 2.3125 feet
= 4.5 cubic feet

For lights I'm using:
3 X 23W:100W Cfl
2 X 13w:60W Red Cfl - Fruiting aid
+
6500K 200W Cfl - Veg
2700K 200W Cfl - Fruiting

I'm thinking that even though they are Cfl, the heat will be too much. I have two 40mm intake and one 80mm exhaust as well as two other 40mm fans for circulation, spliced to a 12vDC 1.7A (Maybe leaving about 0.1A left for it to play with...)
With three 23W:100W Cfl it reaches about 32 degrees Celsius or around 88 Degrees Fahrenheit.
When I add the 6500K 200W Cfl I will need to take out 2 of the 23W:100W Cfl or it'll be too hot.
Then for flowering I will switch out the 6500K for my 2700K and take out the 23W:100W Cfl and add the two 13W:60W Cfl...

So Basically I have two main concerns. The heat and Humidity.
Looking for some innovative cheap ideas on how to control these two. When I begin adding CO2 to the box, will that help at all with the heat or only make it worse?

I don't really get the calculation of how much light I need per space I have...

So any Help or useful thoughts are appreciated. Thanks!

So not a lot of Cfl fans I see...

(For slight Clarification): This item WILL NOT be for sale on this site. Thank you.

Maybe if I change the air circulation?

As it sits:
- One 80mm exhaust top right
- Two 40mm Intake bottom left
- Two 40mm Circulation Fans (Both facing up) placed near top center

Possible changes to look like:
- One 40mm exhaust top right
- One 40mm exhaust top left
- One 80mm intake bottom center
- Two 40mm Circulation Fans (Both facing Down) placed near top center

So Yup! That solved it... Thanks everyone for... well nothing.

Made the changes.
Two ACTIVE 40mm exhaust - one in each top corner.
One ACTIVE 80mm Intake - Bottom Center (Passive intake SUCKS. Who wants a huge ass hole in their grow box 4 times bigger than your exhaust??? Negative pressure can suck my...)
Two 40mm Circulation fans facing down - Top center left/right sides
All on one 12V DC 1.7A adapter. Though sadly was unable to find one cheaper than 15$...
All in all this actually brought down the temp in my box by 10 fucking degrees!

Anyway I imagine many didn't help cuz you're stuck in their "tried and tested" ways.
That's cool, like I say, "Everyone fucks different" BUT I also like to say, "If you don't like me, fuck off". So actually thank you for all those who never added their useless two cents.

Well I hope you keep this thread up to at least help others that won't get any besides this but maybe lock it since there is absolutely no more to say.
Thank you. Have a nice day.

Some more problems have come up. Now when the lights are off, the fans make it too cold.
I was researching some good DC thermostats and found this one: DC 12V Digital Temperature Controller Thermostat C.

But then I thought of another, simpler solution - If the fans could simply shut off with the light, then the cold wouldn't be an issue.
So What I ended up doing was plugging my timer into a three-pronged extension cord, then plugged a power bar into the timer, then plugged my lights and my 12DV adapter (which powers the fans) into that.
Now the fans and lights come on at the same time.

yeah man, you'll want at least one fan inside moving the air around during lights out, frankly, running your exhaust 24/7 helps to prevent things like powdery mildew.

what you could try is a seedling warming mat, or something similar that they make for pets, it MIGHT be enough.

btw, how cold does it get? ...mj can take some cold weather, they just can't take cold below freezing, although if it's really cold that WILL slow growth.

bozo

It was getting to be about 17 deg C lights off.
