Hi ! Due to my ever growing orchid collection, I am expanding my Greenhouse. My current greenhouse is 600 sq. ft. now with two new greenhouses, my total grow area will be 1200 sq. ft. The shade shown is constructed with galvanised steel and painted white. Toughened UV resistant Poly-carbonate sheets are used, they are costlier than glass, but have better strength and heat reflective capacity. Soon the shade cloth will be added and so will be the insect netting along the sides. I will add the pictures as the construction progresses.
