2. Safety Information
Important Safety Precautions:
- Always anchor the greenhouse securely to the ground using appropriate hardware for stability. Failure to do so may result in damage or injury during high winds.
- Exercise caution when handling polycarbonate panels and aluminum frame components, as some edges may be sharp. Wear protective gloves during assembly.
- Ensure proper ventilation to prevent excessive heat buildup inside the greenhouse, which can harm plants and create uncomfortable conditions.
- Protect plants and users from direct, intense sunlight and UV exposure, especially during peak hours. While panels offer UV protection, prolonged exposure should be managed.
- Keep children and pets away from the assembly area to prevent accidents.
- Do not climb on the greenhouse structure.
3. Package Contents

If any parts are missing or damaged, contact Palram customer support before proceeding with assembly.
4. Setup and Assembly Instructions
Assembly of the Palram Canopia Mythos Greenhouse requires two people and approximately 8-10 hours. A level foundation is crucial for proper alignment and structural integrity.
4.1 Site Preparation
- Choose a level, well-drained site that receives adequate sunlight.
- Clear the area of any debris, rocks, or vegetation.
- Ensure the ground is firm and level to support the galvanized steel base.
4.2 Assembly Steps
Follow the detailed, step-by-step graphical instructions provided in the separate assembly manual included with your kit. Key aspects of the assembly process include:
- Base Assembly: Construct the galvanized steel base first. This provides the foundation for the entire structure.
- Frame Construction: Assemble the aluminum frame profiles according to the diagrams. Many connections are partially tightened initially to allow for adjustments.
- Panel Installation: The greenhouse utilizes a sliding panel assembly system. Carefully slide the twin-wall polycarbonate panels into the designated channels in the aluminum frame. This system enhances insulation and wind resistance.

4.3 Anchoring
Once assembled, it is critical to anchor the greenhouse to the ground. The galvanized steel base includes designated holes for anchoring. Use appropriate anchors (not included) suitable for your ground type to ensure stability against wind.

5. Operating Instructions
Proper operation ensures optimal plant growth and extends the life of your greenhouse.
5.1 Ventilation
The adjustable roof vent allows for temperature and humidity control. Open the vent during warm periods to release excess heat and reduce humidity. Close it during cooler periods or when rain is expected.

5.2 Door Operation
The single hinged door can be assembled to open from either the right or left. It includes a magnetic catch to keep it securely closed or open as needed.

5.3 Rainwater Collection
The integrated rain gutter system is designed to disperse rainwater. Consider adding a rain barrel to collect water for irrigation, promoting sustainable gardening practices.
6. Maintenance
Regular maintenance will ensure the longevity and performance of your greenhouse.
- Cleaning Panels: Clean polycarbonate panels periodically with mild soap and water using a soft cloth or sponge. Avoid abrasive cleaners or brushes, which can scratch the surface.
- Frame Inspection: Annually inspect the aluminum frame for any loose fasteners or signs of corrosion. Tighten as necessary.
- Gutter Maintenance: Keep rain gutters clear of leaves and debris to ensure proper water flow.
- Winter Preparation: While the greenhouse is designed for snow load, heavy snowfall should be cleared from the roof to prevent excessive stress on the structure. Ensure the greenhouse remains securely anchored during winter months.
- UV Protection: The polycarbonate panels are 100% UV protected and designed not to discolor, fracture, or shatter over time.
7. Troubleshooting
This section addresses common issues you might encounter.
- Panels Rattle in Wind: Ensure all panels are fully seated in their channels and all fasteners are tightened. For persistent rattling, consider applying a clear silicone sealant along the panel edges where they meet the frame.
- Greenhouse Moves in Wind: This indicates insufficient anchoring. Re-evaluate your anchoring method and ensure the greenhouse is firmly secured to the ground using appropriate hardware for your soil type.
- Water Leaks: Check all panel seals and ensure they are properly installed. Verify that the frame connections are tight.
- Difficulty Assembling: Review the assembly manual carefully. Ensure all parts are correctly oriented and that you have the necessary tools. Assembly often requires two people.
