Greenhouse films are complicated. http://www.ag-con.com/article13.htm
anotherjeff Reviewed by anotherjeff on . Greenhouse question I am in process of building a smallish (500 sq ft) greenhouse. I am going to use plastic as a covering. I notice that pix's of other ghs's that I see have the milkey covering on them, not the clear plastic. The specs that I am able to find shows that the milkey type allows about 90% of the light thru. Question is this: Why not use the clear plastic? Isn't more light better than less? Rating: 5
