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!
