Rubbermaid Grow, LST, and Fans

Hey guys, I got a lot of good feedback on my thread, so here's what I've done. I know it's not the best setup, but it's what I've got to work with right now.

I've built a double rubbermaid (18 gals) container lined with foil. I'm thinking about painting it flat white here soon, so don't worry about that. I've got 3 bagseeds in the soil right now hoping that they'll do something. There are 4 cfls overhead, probably turn it to six here soon.

That's the setup I have so far, but I'm wondering how to block the light out over the fan there. People said that I need a stronger fan to exhaust through the carbon scrubber that I'll make. The one I have is 65 cfm, which isn't much. What can I do to eliminate the light leakage through the fan and attach a carbon scrubber.

Thanks!

It looks like it's been awhile since this was posted, but to answer the question I would suggest dryer vent hose. Yes, you'll want to push more air than 65 cfm to get it though a scrubber.

Hard to tell from the pics, but I assume you have a passive intake at the bottom of the box?
