FRAME, PANELS AND WEATHER
GALVANIZED STEEL FRAME
The galvanized steel frame needs secure anchoring. The right anchoring method depends on your soil, foundation and exposure to wind.
SNOW LOADS AND YOUR LOCATION
Check your local snow-load requirements before choosing a greenhouse. The published test result is a failure load, not an allowable snow-load rating.
UV-PROTECTED POLYCARBONATE
Cellular polycarbonate lets daylight through while providing UV protection.
SHELTER FOR SEEDLINGS AND PLANTS
Give seedlings a sheltered place to grow, with cover from wind and rain.

BEFORE YOU CHOOSE
Questions about your greenhouse
Find out what comes with the kit, how assembly works and what to consider for your site.
ASK AN EXPERT →What is included in the greenhouse kit?
The kit includes all greenhouse components and fasteners needed for self-assembly: reinforced galvanized-steel arches spaced 0.67 m (26.4 in) apart, frame crossmembers, 6 mm polycarbonate panels, two doors, two ventilation windows, boxes of bolts, nuts and other fixing hardware, and ground anchors. Assembly tools and materials for an optional foundation are separate.
Do I need to dismantle the greenhouse for winter?
No. The greenhouse is designed to remain assembled through winter. Keep it securely anchored and follow the assembly and maintenance instructions, including snow removal. Check the snow-load requirements for your location before ordering.
How does the greenhouse handle wind?
Correct assembly and anchoring are essential. The anchoring method depends on your soil, foundation and exposure to wind. Tell us about your site before ordering so we can discuss the available options.
Can the greenhouse be extended later?
Compatible 2 m extension sections can be added to increase the length. Tell us your model when ordering so we can check that the sections match your frame.
Can I assemble it myself?
The greenhouse is supplied as a self-assembly kit. Prepare a level site and follow the instructions for your model. Have someone help you handle the arches and panels. Tools and any materials for a separate foundation are not included.
Which accessories should I choose?
You can add a metal window or a plastic vent, each supplied with an automatic opener. Choose the number of complete kits you need. We’ll confirm compatibility with your greenhouse before payment.
Do I need extra anchoring to prevent wind uplift?
Additional anchoring may be needed, especially in regions with strong winds or on exposed sites. Options include securing the greenhouse to a suitable foundation or setting the ground anchors in concrete. Choose the fixing method for your soil and local wind conditions.
