cool - how will the control strip be kept from exposing? Will covering it with paper be enough? Or is it not treated with photo chemicals at all?

We're working on making two layer coverings for the strips this week so that it is sealed from light, but air can flow through. They are coated with Glycerol and a little bit of photo flow, will post a research note later today on what we did.
