I tested the new Classic greenhouse from Polygrow. Assembled in one day with my partner, the result is stunning in terms of value for money. The polycarbonate is very thick and can bear a serious load. An extra plus is the structure with 14 in ground anchors that keep the greenhouse firmly anchored in the ground.

Update on my experience with Polygrow: support and customer service are top-notch 👍, which makes installing the greenhouse very easy, especially thanks to the videos. The greenhouse is wide and very tall and offers plenty of space. The insulation is first-rate. It came with several free accessories. I am very happy with this choice!

Lots of help before the purchase, including with the shipping. The greenhouse also arrived perfectly packaged. Assembly was a bit difficult for me, but we have harsh weather conditions and the greenhouse was immediately exposed to 62 mph winds, which it survived unscathed!
