A couple more pics of the plants and some of my setup. It's lit by a 250w lamp which runs both MH and HPS bulbs. I've installed a bathroom fan on the ceiling of the cupboard which extracts air out of the cupboard through ducting and out through a vent in the wall. I've hung a 9" deskfan upside down pointing at the bulb to cool it so I can have the lamp closer to the plants. Air is drawn in through a plastic vent at the bottom left side of the cupboard (not visible in pic). On the floor are pallet type things which I made from wooden baton. The idea of these is to raise the pots/container off the floor so water can run out freely and to let air get under them. The floor is covered with black plastic sheeting like what's on the front of the cupboard. The plastic on the front of the cupboard has hook and loop tape (velcro) stapled around the outside of it as does the cupboard itself so it can be sealed shut. Having it sealed shut helps a lot with the smell, I can only smell them when I open the front cover. I have yet to buy some reflective material for the inside, that's all that's missing. And if you're wondering what the black tape is for, it's just to cover the gaps between the peices of hardboard making it light-proof. Not a bad little setup eh?
