fitted wardrobe with grow room behind.

after my current crop is ready, i want to upscale, although lack the space for a tent in my flat. however, i am seriously lacking wardrobe space and was thinking of building a fitted wardrobe into my bedroom. then i would have a chamber behind the wardrobe, accessible from the wardrobe. chamber is about 2m long, 1m deep and about 3m tall, estimated to fit 6 to 8 plants comfortably.

im going to go ahead with this either way, im just curious as to what if any, complications may arise from this? there will be sufficient air flow as i have extractor fan (runing in current setup, can be very easily modified) straight out through a flue pipe in my roof (im top floor flat) i'll be using cfl's (3 in total, maybe 4 space permitting) to reduce heat and lectricity cost.
normal plant pots & soil will be the base and i'll be starting from cuttings, the current cfl im using is dual purpose, has a white/blue side & red side, so i just rotate the bulb when i flip the timers to 12-12, so i'll get more of same cfl's & shade/carrier if available on amazon also, im going to have a rack with the lights & carrier shades on, which i can lower or raise, so i can keep the lights close to the plants.

so, what you recon? i should be ok?

sounds like ya got a plan, that's always the hard part LOL. you didn't say what size those cfls are but more light the better, I'm a trial and error type guy so go for it and modify as problems arise. let us know how it goes.
