U-Haul box grow. Check it out and let me know how it looks.

Dimensions are 21" x 18" x 46" (10.0 cu/ft).

Painted with flat white paint.

12x 26w 6500k CFL's for veg 19320 lumens- 12x 26w 2700k CFL's for flower 21000 lumens.

Door is Velcroed shut.

3x small personal fans for intake, exhaust and blowing air around inside.

Square cardboard insert that is the same length and width of the box which goes above the lights for a reflector - also painted flat white. It can be removed and placed at three different heights for when the plants get bigger.

Wooden stiring sticks for paint used to reenforce the frame and also the door to keep it from bowing in/out.

Heat is still an issue inside the box. I have a 400 cfm fan that I ordered about a week ago which will make light work of this box - hopefully. Going to do 1 white widow and 1 blueberry in here using a SCROG. Seeds are germed and I put them in small party cups. They're just now starting to stick out of the soil by about 1 cm. Using some cheap Wal Mart potting soil with no nutes right now. After a couple weeks I'm transfering to 5 gal buckets of FFOC soil.

Nice looking box, hope to see some nice plants growing in there soon.

It looks good! If you ever wanna make a germination box to go with it here's mine
It has 8 light sockets I ca swap between and being so little the heat exhausts fast and it's perfect for seedlings.

If you are worried about heat in your box you can do without about half the cfl's early on, or more.

Also, I'd suggest putting an exhaust fan on the roof above the lights, that little bit of light that shows through means that enough air would be able to get out and you could put a filter on it if you wanted to. Do you have something you could put on the bottom incase of an over run drainaige? I could see that wrecking your whole project, and worse, molding your floor, or did I miss that too?

Edit: I see you said 3 fans I guess I just missed one

Yeah, intake and the fan which blows air around the room are in the bottom. Exhaust is on the top.

Excellent! I'm a bit of a Macguyver grower too, I'm working on a rubbermaid 50 galling x2 with a transferable pulley operated lighting system with cfls up the side atm. Oh, that's one thing you are probably gonna want to get is a few light sockets and wire it into the sides going up, and during flowering you can add extra 2700k's to get the lower leaves. Makes a HUGE difference.

I'm going to SCROG so side lighting should not be an issue - hopefully. If it becomes one, I'll probably do the same thing you did and put some lights through the side walls of the box. Good info.

Looks good. I assume you can easily adjust the light height in there?

really awesome budgt set up. whos needs to drop a couple grand on a grow room when you can make one like this for under $100.
