I have started to buy the supplies for the shelves. I figure I will start by putting down the foam insulation on the bottom shelf with the aluminum side facing up. After this the heating cable will be added with aluminum tape and topped off with capillary matting. The misting system will added under each shelf for over head watering. If this works well and reflects the heat I will be adding it to the others all the way up. If not I will just be adding the heating wires directly to the metal shelves. After this is done I plan to add plastic to curtains to keep the shelves very high in humidity. I am still trying to figure out the easiest way to construct the curtains. I have plenty of greenhouse plastic but I will need it to be easily opened to retrieve trays and easily closed. Any Ideas?
