Still standing after the storm

Reinforced steel and deep-ground anchors hold it steady, so you're not worrying every time the wind picks up.

Built for heavy snow

Reinforced arches shed snow before it can pile up and stress the roof, so it's ready for whatever winter brings.

Panels that take the hit

Twin-wall polycarbonate is 200× stronger than glass. Hail and debris just bounce off, year after year.

Extended farming

Start planting earlier in spring and keep harvesting later into fall, well past when the garden usually winds down.

One model. Six lengths.

We do one thing and do it right: a single proven model, in six lengths.

★★★★★

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 50 kph without any issues."

Frequently asked questions

How does pre-ordering work?
We're currently sold out of in-stock units, so all orders are pre-orders from our next production run. You lock today's sale price at checkout, production takes 7 weeks and delivery about 5 weeks — order today and your estimated delivery is . Pre-orders ship free across the US and you're covered by our 30-day money-back guarantee.
Can I assemble it myself?
Yes — it's designed for DIY. Two people and a weekend is typical, using basic hand tools. Every kit ships with an illustrated step-by-step manual, and customers in their late sixties have completed the build solo. If you get stuck, our support line walks you through it.
Will the frame hold up in heavy snow?
The arched galvanized-steel frame is rated for 3 ft of snow (32 psf) and 65 mph winds. The rounded shape sheds snow before it can pile up, and T-shaped anchors set 13.5–16" into the ground keep everything planted. For extreme snow regions, add the telescopic roof supports.
What's actually covered by the warranty?
A 10-year warranty on the frame and 5 years on the panels, covering manufacturing defects and weather damage within the rated limits. You can upgrade to a lifetime warranty at checkout. Returns are free within 30 days of delivery.
Do I need a building permit?
Most US municipalities treat greenhouses under 200 sq ft as accessory structures that don't need a permit, but rules vary by county and HOA. Our largest model is 150 sq ft. Check locally — and note that this greenhouse's certified 65 mph wind and 3 ft snow ratings have helped customers pass city code where cheap kits couldn't.
How long do the panels last?
The 1/4" twin-wall polycarbonate has UV protection built into the material, so it resists yellowing and stays clear for 10+ years. It's 200× stronger than glass and 70% stronger than standard single-wall polycarbonate.
Does polycarbonate cut light to plants?
Twin-wall polycarbonate transmits about 80% of light while diffusing it — plants get even, gentle sun from all angles instead of harsh direct rays. That means no leaf burn and more consistent growth than glass.
What's your return policy?
30-day money-back guarantee from the day your greenhouse arrives. If it's not what you expected, contact support and we'll arrange the return. Pre-orders can be cancelled for a full refund any time before your unit ships.
