Build A Cheap Greenhouse Using Plastic
So, what are the advantages and disadvantages of plastic greenhouses. Polyethylene, Vinyl, Renolon, or other types of transparent plastic are low cost items compared to real glass though it does depend on the thickness you choose. These plastic materials are easily attached to the greenhouse framework and all puttying is avoided. It’s possible to build a cheap greenhouse such as a small 6- by 8-foot free-standing greenhouse for very little money providing, of course, that you do all the work yourself.These modern, and improved plastics are very good at resisting strong winds and heavy snow, and they can transmit up to 98 per cent of the sun’s visible light energy—as much as passes through good glass. Some plastics also transmit up to 80 per cent of the ultraviolet rays, which is greater than through glass.
