installing a large swap cooler

[Susan]

Texas Heat. high 90's today and the greenhouse, an 8'x15' gothic arch fiberglass. Is way hotter, probably around 115. Just started one system inside over the week end but how to bring the heat under control. Short of installing a large swap cooler....fans won't cut it. Also, it is green and cuts down 36% of UV but no affext on the heat......IDEALS??????

I use 70 percent shade cloth here in Florida to grow everything. But in July and August it is almost impossible to grow anything even with shade cloth. So that's when everybody shuts down and cleans their greenhouse and gets ready for the fall planting.
