I have a 12X12 greenhouse with wood frame and would like to cover it with regular greenhouse poly this fall but so far have not figured out how to go about it and still have the plastic guaranteed for 3 yrs. Everything I've read says the plastic cannot touch wood and it would cost around $120.00 for two layers so I would definitely want it to last as long as possible! The past three years we have used regular 6 mil plastic and it works ok but deteriorates within a year so has to be changed AT LEAST once a year(sometimes more) , which is a real pain in the rear!

Anyone got any suggestions.................or know where I can get greenhouse 6 mil poly cheaper?
Thanks for any advice!
