Building a greenhouse
I'm building a new wood frame greenhouse. I'm wondering what's the best covering to use. I'm thinking of using the corrugated fiberglass. I don't think a plastic covering would last in the valley. I'm afraid of the sun ruining it. I'm looking for something that would last a few years and from what I've seen the plastic only last 2 years or so.
What type of covering do you use? Any suggestions would be great.
