Setup Instructions

Follow these steps carefully to assemble your Ohuhu Walk-in Greenhouse. It is recommended to have at least two people for assembly.

Step 1: Assemble the Base Frame

• Lay out all base frame components (floor supports and horizontal supports) on a flat, clear surface.
• Connect the floor supports using the shorter bolts, ensuring they form the rectangular base.
• Attach the horizontal supports to complete the base frame. Tighten all screws securely.

Step 2: Install Vertical Supports

• Insert the vertical support poles into the designated connectors on the base frame.
• Ensure all poles are oriented correctly and are firmly seated.

Step 3: Attach Diagonal Supports and Curved Supports

• Attach the diagonal supports to the vertical poles and base frame for added stability.
• Begin attaching the curved roof supports to the top of the vertical poles.
• Fasten these connections with the appropriate bolts and screws.

Step 4: Complete the Roof Structure

• Continue assembling the remaining horizontal supports to connect the curved roof sections.
• Ensure all connections are tight and the frame is rigid.

Step 5: Install the Greenhouse Cover

• Unzip all doors and windows on the cover before placing it over the frame.
• Carefully pull the cover over the assembled frame, ensuring it is centered and aligned.
• Use the Velcro straps and ties inside the cover to secure it to the frame.
• Adjust the cover to ensure the door seams align with the door frame.

Step 6: Secure to the Ground

• Tie the ends of the provided ropes to the ground stakes.
• Insert the stakes into the ground on both sides of the greenhouse, across the top, and along the base.
• For additional security, place heavy weights like stones, bricks, or sandbags on the extended side of the cover along the ground.

Operating Instructions

Proper operation of your greenhouse ensures optimal growing conditions for your plants.

Ventilation and Temperature Control

• Dual Zippered Screen Doors: The front and rear doors feature dual zippers and screens. Unzip the outer layer to allow air circulation while keeping pests out. For maximum airflow, roll up both layers and secure them with the ties.
• Roll-up Screen Windows: The greenhouse includes 6 roll-up screen windows on the sides. These can be opened and secured to provide additional ventilation and help regulate internal temperature and humidity. Close them during cold weather or when higher humidity is desired.

Watering

Water plants as needed, considering the increased humidity and reduced evaporation within the greenhouse. Monitor soil moisture regularly.

Maintenance

Regular maintenance will prolong the life of your greenhouse and ensure optimal performance.

Cleaning

• Clean the greenhouse cover periodically with mild soap and water to remove dirt and debris, which can reduce light transmission.
• Avoid using abrasive cleaners or brushes that could damage the cover material.

Inspection

• Regularly check all frame connections to ensure bolts and screws remain tight. Retighten as necessary.
• Inspect the cover for any tears, punctures, or signs of wear. Small damages can be repaired with appropriate greenhouse repair tape.
• Verify that ground stakes and ropes are securely in place, especially after strong winds or heavy rainfall.

Seasonal Care

• In areas with heavy snowfall, regularly clear snow from the roof to prevent structural collapse.
• During periods of extreme heat, ensure maximum ventilation to prevent overheating.

Troubleshooting

Here are solutions to common issues you might encounter with your greenhouse.

• Greenhouse unstable in wind: Ensure all ground stakes are fully inserted and ropes are taut. Add additional weights (bricks, sandbags) around the base of the cover. Consider relocating to a more sheltered area if high winds are a persistent issue.
• Excessive condensation inside: Increase ventilation by opening doors and windows. Ensure adequate air circulation to prevent mold and mildew growth on plants.
• Difficulty zipping doors/windows: Ensure the cover is properly aligned and not overly stretched. If the zipper snags, gently work it back and forth. Avoid forcing the zipper.
• Plants not thriving: Check internal temperature and humidity. Adjust ventilation as needed. Ensure plants are receiving adequate light and water.
