I am thinking about buying a piece of ~ 75'x45' greenhouse
"Shade Cloth" to completely cover the new greenhouse, which
is covered with 2 sheets of 6mil poly.

Questions:
1. What percent shading factor?
2. Brand?
3. Color?
4. Best place to buy?
5. Any idea how to determine the life of 6mil greenhouse
poly, when under greenhouse shade cloth?

THANKS,
Gene
