Hey keeron,

I did practically the same thing, only I got the frame for my tent from B&Q, it was a mini greenhouse and I replaced the clear plastic cover with blackout sheeting. I didn't spend much time making mine, I just taped the blackout sheeting onto the frame, bits of the taping needed to be replaced from time to time, the door I made bigger than the opening and just taped round the side (it would be better to get some velcro to keep the door closed better) And I didn't put a floor in my tent which you probably need to do to make it lightproof. (it wasn't really a concern for me as the tent was in the loft and i didn't need to worry about light getting into the tent) It definately works, just take a little time to think it through before you you build it, try to imagine where your lights are gonna hang from and where the wires are gonna come in etc. I'd go for a wooden framed drobe, it'll be easier to work with should you need to screw in an extra bit of wood to support your light/fan and will prob be better to attach your blackout sheeting to, you could staple it in position which will be better than my taping onto a metal frame.

Good luck with it dude, keep us updated as to how it's going and shout out if you want anymore advice.
