Slowly foiling one of my upstairs bedrooms as I start the long process of turning it into a plant room.
The foil is for reflecting light, something you can see that it does in abundance, especially by the second photo.
I'll definitely have to foil at least this whole wall and probably the door, as there is only the one window.
My plan is to finish this wall (it takes about 5 minutes per section to adhere it properly) then start work on covering the floor in a layer of waterproof plastic so I can start bringing in shelves.
The plan is to eventually foil the whole room so the grow lights can bounce off it for maximum effect, but right now I'll settle for the back wall not being a light-sink.
