Customer Reviews

By mrs valerie abel on 7th May 2025

"The Greenhouse is just as described and is going together well. We have constructed the bottom half and two of the roof panels and I'm hopeful my husband will put the other four panels on the roof tomorrow. Compared to the metal greenhouse, which never did get completed before it blew down in a storm last December, this one looks much more robust and I can't wait to use it."
