Need Major Help With Inline Fans, Air Circulation and Misc

Hey everyone!

I'm in the process of collecting stuff for a grow room.

I currently bought 4'x50' of Mylar, a liquid root stimulator from Wilson® (is this any good for cloning?), 5 reflectors, 50 Florescent bulbs, 3 bags of soil (18L each), a dehumidifier.

I currently need: an inline fan, a squirrel cage fan, aluminium tubing, 2 grow boxes (might be able to make one), 12 more bags of soil, flower pots and visqueen plastic.

Am I missing anything?

The problem with the grow room is that it's in an unfinished room which has no source of air to come in. I'm guessing the room is about 7'-8' wide, 9'-12' long, by 7'-8' in height. There's ventilation tubing inside, along with a furnace/water heater, but I am a little worried about messing around with the tubing as I don't know where it all leads to. I will take pictures of the room once I move into the house.

I don't know where to vent out the air (how can I find out where the air goes from the various tubes in the room?), I'm afraid of getting mold, afraid of the dehumidifier starving the plants of humidity, it might be too noisy, etc...

This seems like a ton of work!!

Any help is appreciated!

you should return the fluorescent bulbs and get some T5's or HID lighting. 50 CFL's? Wow!!!
