Hey Comatose, thanks for stopping by and giving input.

I'm lucky that I have pretty dark containers but taping them up will definitely help. When I do I will be using aluminum duct tape rather than traditional cloth duct tape as it blocks light with a single application. I will also add a couple of check valves - one for each air feed line - to keep the system from backflowing into my air pump and causing problems.

I encourage anyone that has ideas or suggestions to post them here so that we can spread the info and learn from each others experiences and mistakes.

I have seen friends use store bought units that are similar (google for Emily??s Garden). If you wanna see the concept, check out Greg Green's book "The Cannabis Grow Bible" where this idea is discussed as well.
