I just took the dimensions of one of my hoods so that I could make another. I can give you the dimensions, but I'll assume that you're privy to metal frabication.

End View:
13 inches across bottom
6 inches across top
2 inches up from either side of the bottom at a right angle
6.5 inches from the top of the 2 inch sides to the 6" top

Looks kind of like this:
``_____``
`/`````\`
/```````\
|_______|

Side view:
24 inches long
7.5 inches high
looks like a rectangle from the side.

If you follow this, you'll get a 120 degree hood, which is standard.

I wonder if Dracula ever has ticks.

The metal that I used is awfuly similar to the metal used in street signs. I'd suggest finding one big enough (2 feet x 2 feet), but that would be illegal.

...You can use a hurricane globe that you can get at WallyWorld or any arts and craft shop. They are used as decorations over big candles. Here is a pic:

This is my set-up. Very easy. I would suggest atleast a 180cfm or more for your exhaust fan. Depending on how long the duct is. Don't be cheap with the fan or else you will be buying another one like the can fan. I didn't take the advice from here and now I have a collection of cheap fans! GL...

...No prob. If you make Throwgars deal you can hook the tube up easy. Also checkout Louisville97 threads. I think he has a post on his homemade set-up, if not, PM him and he'll send you his plans.GL...

...The globe is open on both ends. I drilled four tiny holes in the reflector and tied the globe in place with wire. I taped the duct to the oppisite end of the socket. It works good for me. Please, don't be cheap on a exhaust fan. Like I stated somewhere b4 I have a collection growing of cheap inlines. I just can't believe the prices they get for the good ones...

Edit: Look at the pic again above and you'll see the gold wire around the globe...

I also preach the "don't buy a shitty fan, since you will have to buy a new one" as well.

Something to consider when making a reflector is the safety factor. That candle globe works well for ventillation, but if that bulb ever exploded it wouldn't do much good to keep the 1000 degree shrapnel from spreading all over your grow room.

It DOES happen. One of my 1000 watt MH lamps blew a month or two ago. If it wasn't for my tempered glass shield, I'm pretty sure that my house would have caught on fire.

...Gotta good point there. I would have used those pie-rounds from pyrex but I couldn't find them, but I didn't spend much time looking either. I gotta replace my bulbs after this harvest. Might just change them over then. I bought a cooltube for my 600 and thats got some meat in her. Good tip. That vortex fan I got will make yer asshole whistle!...
