Thanks for asking, diggity. I'm think I'm going to make a can style filter with the carbon. I've got most of the materials together, just need to find the time.

So I can still use the fan I have the inside of the can will be 6" and the outside will 8". With the amount of carbon I have the can would be only 10" long, so I'll be buying more and make it about 18" L. Do you think that sounds OK?

As for the box I made, I took 2 of the 4 filters to help increase air flow. Since my biggest problem is heat I needed to move more air. In the end it will probably end up being an over done Y-pipe to cool my lights.

Things aren't to critical right now. Real soon I will be making some changes to my room. As long as it is done by then I'll be happy. I do plan on making a air cooled hood for my light as well.

Make it well and it should do you well..

I have a few pics of what I have so far. Still need more carbon and a inner and outer liner. I'm considering a stocking for the inner, but don't know how I feel about using it on the outside. Will it really hold the carbon in place? I'll probably try it with a stocking first if it doesn't work well I'll try a filter.

With the screens, as long as itspacked well, and the nylon is stretched to a decent tension, it should.. If mounted horizontally, and it rustles to become a little bottom-heavy, just add more carbon up top..

I used a black stocking and it worked good at holding the carbon in on my carbon filter

Here's some pics of my diy filter:

Nice filter! Hope you don't mind a few questions....

Is it 6" out of the filter, and 8" out of light? Or is it 4" and 6"?

Does that move enough air to cool the light and effectively filter the air?

250W right? How many CFMs?

I am using a 306 CFM inline fan, here is the link: http://www.hydroponics.net/i/133758

It is six inch coming out of the light and 4 inch out of the filter. The outer core of the filter is 6 inches and the inner core is 4 inches. Here is a link to the instructions I followed to make it: http://www.icmag.com/ic/showthread.php?p=509470

And yes I am using a 250 watt in the reflector but there is a 70 watt HPS next to it and the temps are just fine exhausting through the filter
