  1. Two other greenhouses worth considering – Flower Power Pop-up. Mine lasted 2-3 years even though I left it out in the winter to store terracotta pots. But it was a pain to put up. Replaced with Eagle Peak model. Easier to put up, frame is much sturdier, but plastic covering seems a little thinner than FP model.
