Alright, so I need a new chamber, because I want to have a mother and be able to take clones and stuff while I'm flowering. I don't really have any more room for furniture in my bedroom, and I don't want it to be in the living area, so what will I do? Well, I've got some closet space that I'm not using, so I decided to turn a garbage can into a veg chamber. It hasn't been put to use yet, but I see no reason for it not to work. Since it will only be for veg, I'm not bothering with filtering the odor or making it 100% lightproof.
I'll be using a Rubbermaid 30~ gallon trash can, green with a tan lid. I got this from WalMart for $10 maybe? Somewhere around there I think. I then bought two mylar blankets from WalMart for less than $2 each. These provided more than enough material to quadruple layer around the inside of the garbage can. I did this for two reasons. The first, so the whole thing doesn't glow. I forgot to do the top, and it looks ridiculous, but where I put the mylar, it looks like a regular old trash can.
For my lights, I've got four 15w CFLs, 6400k. The garbage can is about 1.5' across, which leaves me with appx 1.75 sq feet. With the 60w of light I have, that's 35wpsf of light, perfect for vegging. (I use 50wpsf for my flowering cabinet.)
For ventilation, I'm using a 120mm computer fan. It's rated at 47cfm, is blowing completely unrestricted, and is absolutely silent. I feel that this fan will be sufficient ventilation, as I don't need to push through light traps or carbon filters. There is a 4"x8" rectangle cut out on the bottom of the garbage can to act as passive intake. (Intake area = 32sq in)(Exhaust area = 17.5sq in~) I was shooting for intake=exhaust*2, it should be close enough. I doubt the 60w of CFLs will produce much heat at all.
I've got a wooden 2"x1" punched through the cover. The wires and lights hang off of this.
And here it is, up and running. It's been on for about half an hour now, and the temperature inside stays at ambient, so it looks like the ventilation is sufficient. I've got six seeds germing, so I should be getting some plants in there shortly. If you've got any questions, I'd be glad to help.
Note: Edited a few pictures due to my own paranoia.
