LOL! Emmie is an economics major....can you tell? Can you write that up as a formula, Em??? Maybe we can get them to sticky it and point all "what will my yield be" questions to it...your getting close to that AWESOME level girl! Soon we'll be calling her Awesome Em!

Wassup Dr. Nick! You probably want something slightly bigger than a PC case...if your going to build it yourself there are lot's of cool newer materials to use to do this with...wander around a big box store like sLowe's or Home DePot and look at the reflecting foam board, and foil tape to build an insulated box with, whatever size you finally come up with...say you get a 250w HID (HPS? MH? Or both switchable would be ideal) Pick the light and make sure you can vent the heat good, and go from there...depending on the light configuration, you can get a pretty good idea what size you'll need to grow a couple of nice sized plants, (2-2 or 3 footers should do nicely) which should be enough for what you desire for a stash. An old Fridge might be good if your looking for total camo...tho a bit harder to convert, it's insulated well and nobody pays much attention to an old fridge sitting around...the reflecting foam board they have out now, makes me want to build a new room, even tho I have no need for it! LOL! Very easy to work with!
