7X
stronger glass
Tempered safety glass is up to 7 times stronger than regular greenhouse glass. If it ever breaks, it crumbles into small, blunt pieces instead of sharp shards. Stronger, and safer around the garden.
Built stronger. Lasts longer.
grows clearer
Tempered glass, a rust-proof aluminum frame, and a shape that sheds weather. Here is what that means for how long it lasts, and how well it grows, in your yard.
95%
light transmission
Glass passes up to 95% of natural light with no diffusion, ideal for orchids, citrus, and light-hungry plants. It stays clear for decades and does not yellow or degrade from UV like polycarbonate eventually does.
115 MPH
weather tested
The reinforced rust-resistant aluminum frame is rated to 115 mph winds and built up for heavy snow loads. A full 6'7" interior height lets you garden upright without hunching, season after season.
When to choose glass over alternatives
Perfect for gardeners who value aesthetics and want an heirloom-quality structure that adds to their property.
Perfect for limited-sunlight climates
Glass provides up to 95% light transmission, making it ideal for growing light-hungry plants, orchids, and specialized collections. This direct light is especially valuable in northern climates with limited winter sunlight.
Lasts 30+ years
Glass panels can last 30+ years with proper maintenance, often outlasting the frames that hold them. While individual panes may occasionally need replacement, the structure keeps its clarity and won't degrade from UV exposure the way polycarbonate eventually does.
Even in small spaces
Full 6'7" height lets you garden without hunching, while the spacious 41 sq ft+ interior provides room for both plants and relaxation.

What customers say
Highly recommend
"We had a really bad wind storm (Tornadoes in the area) and the greenhouse didn’t budge! We are so pleased with the quality. It’s a big project to put together, but well worth it."
The quality is solid
"It held up great thru some of the heaviest snow in years. The greenhouse also stayed bone dry despite the snow melt and heavy spring rains. We also experienced some days with sustained high winds in excess of 50kph without any issues."
I Love my Greenhouse
"Bruno and his team have been very helpful when we reached out to get help on assembly. Even though my boyfriend and I have no building skills they made it relatively easy. I believe that their pricing is very reasonable for the high quality of the materials. Mahalo Your Greenhouse"
