1. Important Safety Information
Before assembly and use, please read and understand all safety instructions. Failure to follow these guidelines may result in product damage or personal injury.
- Take protective measures for the greenhouse before anticipated bad weather conditions.
- Secure the greenhouse in windy conditions with extra ropes when wind speeds exceed 24 miles per hour.
- Install the greenhouse away from direct wind exposure to minimize stress on the structure.
- During snowy conditions, keep the outdoor greenhouse clear of snow. Snow accumulation should not exceed 2 inches to prevent structural collapse.
2. Product Features
The EROMMY 20' x 10' x 7' Greenhouse is designed to provide an optimal environment for plant growth with robust construction and user-friendly features.
- 8 Roll-Up Mesh Windows: These windows facilitate cross-ventilation and climate control. They are equipped with mesh netting to prevent insect entry and feature convenient Velcro and straps for easy opening and closing.
- Heavy-Duty Powder Coated Steel Frame: The solid steel construction features a galvanized finish, offering resistance to rust, chipping, and peeling. Poles are securely connected by screws. The stable frame incorporates a triangular structure for enhanced stability, complemented by 6 top cross bars and 8 side slope tubes to prevent rain and snow accumulation.
- Reinforced PE Cover: A tough, durable, and transparent polyethylene plastic cover protects plants while allowing nourishing sunlight to pass through. The cover is easily attached to the frame using included tethers and single-sided tape.
- Overlong PE Cover Design: The extended cover can be secured to the ground by placing stones or bricks on it, or by burying it in the soil. This design improves air tightness, heat preservation, and overall stability of the greenhouse.
- Roll-Up Door: A large zippered roll-up door provides convenient access to the interior and can be secured in an open position.
3. Setup Instructions
Careful assembly is crucial for the stability and longevity of your greenhouse. It is recommended to have at least two people for assembly.
3.1 Unpacking and Part Identification
Before beginning assembly, unpack all components and verify against the packing list. Ensure all parts are present and undamaged.

3.3 Cover Installation
Drape the PE cover over the assembled frame. Ensure it is evenly distributed and taut to prevent water pooling. Secure the cover to the frame using the provided tethers and single-sided tape. Utilize the overlong edges of the cover by burying them in soil or weighing them down with heavy objects for improved sealing and stability.

3.4 Anchoring
Properly anchor the greenhouse to the ground using the fixed drawstrings and ground nails. This is critical for stability, especially in windy conditions. Additional anchoring methods, such as concrete borders or extra ropes, may be necessary depending on local weather conditions.

4. Operating Instructions
Effective operation of your greenhouse involves managing ventilation and climate to suit your plants' needs.
4.1 Ventilation and Climate Control
The greenhouse features 8 roll-up mesh windows and a large roll-up door to manage airflow and temperature. Open windows and the door to increase ventilation and reduce heat, especially on warm days. Close them to retain heat and protect plants from cold or pests.

4.2 Plant Placement
Arrange plants inside the greenhouse to optimize light exposure and air circulation. Consider the specific light and temperature requirements of each plant type.
5. Maintenance
Regular maintenance will extend the life of your EROMMY greenhouse and ensure optimal performance.
- Clean the Cover: Periodically clean the PE cover with mild soap and water to remove dirt and debris, ensuring maximum light transmission. Avoid abrasive cleaners.
- Inspect the Frame: Regularly check all frame connections and screws for tightness. Tighten any loose fasteners to maintain structural integrity. Inspect for any signs of rust or damage to the galvanized coating.
- Check Anchoring: Ensure that the greenhouse remains securely anchored to the ground, especially after strong winds or heavy rainfall. Re-secure or reinforce anchoring as needed.
- Winter Preparation: As per safety guidelines, clear snow accumulation promptly. Consider additional insulation or heating if growing temperature-sensitive plants in cold climates.
6. Troubleshooting
This section addresses common issues you might encounter with your greenhouse.
- Greenhouse Collapses or is Unstable in Wind:
Solution: The frame may require additional reinforcement. Consider adding extra support in the center of every other section and using 16 gauge wire to create additional struts. Ensure all anchoring points are fully utilized and secure. Relocate the greenhouse to a more sheltered area if possible. - Water Pooling on the Cover:
Solution: Ensure the PE cover is installed tautly across the frame. If sagging occurs, re-adjust the cover tension or add additional support beams beneath the affected areas to prevent water accumulation. - Difficulty with Assembly:
Solution: Lay out all parts and carefully identify them using the packing list before starting. Follow the assembly steps sequentially. If instructions are unclear, refer to online resources or contact customer support. - Mesh Windows Deteriorating:
Solution: Over time, exposed plastics can degrade. If mesh windows show signs of wear, consider patching or replacing the affected sections to maintain pest protection and ventilation control.
