There's a guy here named "stealthy" he has some neat setups you should run a search on him here at RIU.
What you need is small cabinet, could be wood, drywall, plastic, an old fridge, whatever you want that could be disguised. You need to provide the basics: Light, Air, Medium and Co2 and then you need to control the secondary variables like temperatures and RH. There's specific gear for each one of those task that you'd need to buy an a Hydroponic or hardware store.. There's a third variable involved with plant height. If growing with CFLs your finished plant should never be taller than 14-18", SCROG/Training might be needed in most of the cases. Last but not least, is odor control:make sure your GR is Air tight, no cracks, no light leaks, nothing!! you could make some DYI yeast Co2 makers and run your tent completely isolated from the outside word- It's mandatory to get an Activated charcoal filter please DYS a favor and get a CAN rather than the cheap growbright.
Hi Kayagold and fellow growers! Have you considered growing under your bed instead? it'd be alot easier (in theory). Post some pics of all possible locations around the house where a grow would go unseen ie under your bed, in an bedside cupboard and God forbid.. even a PC Case (big) etc etc....
