"Gardening Conditions Have Changed. Your Greenhouse Should Too"

Many older greenhouse materials weren't designed for today's climate swings. Our Polycarbonate greenhouses delivers the strength, insulation, and longevity modern growers need.

What The Greenhouse Needs To Handle:

  • Stronger seasonal storms

  • Heavy snow loads

  • Hail and falling debris

  • Larger temperature fluctuations

  • Rising replacement and maintenance costs

Many older greenhouse materials can't keep up with these conditions

Our Polycarbonate Greenhouse Outperforms Every Other Greenhouse

See 4 engineering advantages that regular greenhouse materials can't match

Impact Resistance

Our panels are engineered to withstand heavy hail, debris, and accidental impacts. 

Improved Insulation

Proper twin-wall construction and durable framing allow growing in heat, rain, wind and snow

Light Diffusion For Healthier Plants

Our panels spread sunlight evenly across your plants, helping reduce burn spots and supporting balanced growth. 

Lower Maintenance

Our UV-protected panels are engineered to resist yellowing and degradation over many growing seasons. 

Details That Set Our Greenhouses Apart

1. Panel Thickness & Quality

1/4"  double-wall polycarbonate, 70% stronger than standard. Better insulation with less heat loss.

2. Ground Anchoring

T-shaped anchors sink 13.5-16 inches deep, keeping your greenhouse grounded in severe storms.

3. Frame Strength

50% stronger than typical galvanized steel, so your frame won't bend under heavy snow.

4. Corrosion Protection

Galvanized steel framing resists rust, so the structure stays strong season after season.

5. Arch Spacing & Reinforcement

Closer arch spacing distributes weight evenly. Reducing the stress points where most greenhouses fail.

Expert's Checklist: 5 Critical Factors

When comparing greenhouse options, we recommend evaluating:

Steel thickness and structural reinforcement

Panel thickness and UV protection

Arch spacing and frame support density

Ground anchoring and installation stability

Warranty coverage and material protection

Understanding these details helps ensure your greenhouse performs reliably for years, not just during the first season.

Frequently Asked Questions.

Does polycarbonate reduce plant growth light?

No. Our twin-wall polycarbonate panels transmit 80%+ of available light while diffusing it evenly across your plants. This actually helps growth — plants get consistent light without the harsh direct sun and burn spots that glass creates.

How long do polycarbonate panels last?

Our panels come with a 10-year warranty. With proper care, most panels maintain their clarity and structural integrity well beyond that. UV protection is built into the material to prevent premature breakdown.

Will the panels discolor or yellow over time?

Our panels include UV-protective coating specifically designed to prevent yellowing. Unlike cheaper polycarbonate that can cloud within a few seasons, our panels are engineered to maintain clarity for years.

How strong are the frames in heavy snow?

Our greenhouses handle up to 3 feet of snow (32-49 psf depending on model). The 3 1/16" galvanized steel frames are 50% stronger than typical galvanized steel, and the arched designs let snow slide off naturally.

Can I assemble the greenhouse myself?

Yes. Most customers complete assembly in a single weekend with basic household tools and a helper. Every greenhouse includes step-by-step instructions and a video assembly guide.

Do I need a permit to install a greenhouse?

Permit requirements vary by location. Most residential greenhouses don't require permits, but we recommend checking with your local building department before installation. Our greenhouses meet 65 mph wind load requirements, which satisfies most local building codes.
