kingsloth, you can do a lot with a little. check out my grow. my dimensions are something like 27" x 19 1/2 x 20". i can't exaclty remember. and this is my first grow, so i don't know what the yield is gonna be.

you can always go ebb & flow and put the res underneath the grow cab on some legs.

what kinda light you going with? all i saw was light socket. you're gonna need more than one if you are running CFLs.

make sure to get a thermometer.

depending on your size get an appropriate fan/fans. make passive intakes that double your the total size of your exhaust fans.

think about any luxuries you might want. it's yours. you are gonna be using it.

you can put "invisible" hinges on it. not sure if those are the name, but the ones that you can access from the outside. you can put a biometric fingerprint reader on it. you can put a webcam in it and monitor from your phone (with the right equipment and software). so really the sky is the limit. use your imagination and have fun with it.
