We will build a roof structure above the 8ft drywall , use the plastic, and hopefully use some sort of lightweight blackout material for added protection.
This roof will hopefully a lightweight solid attachment that effectively blocks out light from above.
Air, Exhaust will be supplied from the roof into specific areas of the lab.
