Review Summary

This is the summary of consumer reviews for U-MAX Polycarbonate Outdoor Greenhouse 6'(L) x6'(W) x6.6'(H). The BoolPool rating for this product is Good, with 3.20 stars, and the price range is $249 - $309.

The U-MAX Polycarbonate Outdoor Greenhouse is a rigid greenhouse structure made of UV-resistant polycarbonate. This thermally insulated greenhouse can withstand the elements and protect plants, all while holding them in a spacious room that is also easy for gardeners to get around. The greenhouse requires some set up but can be secured easily and is also lightweight for moving or transporting. 

This greenhouse seems to work well for many gardeners and plant enthusiasts. They say assembly can be done in a few hours and then it is ready to go into use. They say the room gets toasty warm without harming the flowers and plants. Some say this greenhouse is wind resistant, many saying their greenhouse sustained winds of up to 40 miles per hour and did not falter.

Many say assembly was very difficult, especially because the directions are quite poor. They say they are hard to understand and it takes longer than a few hours to assemble. Others say they do not know if the material of the window panels are plastic or true polycarbonate material. For this reason, they were dubious about the product.
