Backyard greenhouses compared

26 greenhouses from 16 brands, sorted by our score. A pop-up or tunnel greenhouse is a steel frame with a PE plastic cover: cheap and big, but the cover lasts a few seasons. A polycarbonate kit has hard panels on an aluminum or wood frame. It costs more, holds heat better and stands for years.

Our score counts what the listing states: wind rating, snow rating, warranty, panel type and buyer ratings. We leave price out of the score on purpose, because a $150 tunnel would beat every hard-panel kit on price per square foot. Read the greenhouse buying guide before you order.

A question mark means the listing does not publish it. "Poly" means polycarbonate with no stated thickness. "Stated" means the listing gives a snow depth instead of pounds per square foot. Prices are the last ones we saw on Amazon.com (28 Oct 2026).
