3.2. Key Assembly Steps (Summary from Video)

1. Prepare the Base: Assemble the base frame components (B2, A2, C2, D306, D307) using the provided bolts (S01, M01). Ensure the frame is square and level. Secure the base to the ground using ground stakes (D144, S69) for stability.
2. Construct Wall Frames: Assemble the vertical and horizontal wall frame components (L01A, L01B, L08C, L10A, L10B, L10E, L10F, L23C, L23G, L26A, L26B, L10C, L02A, L07C, L26C, L26D, L26G, L26H, D317) using bolts (S01, M01) and screws (Z08).
3. Install Polycarbonate Wall Panels: Carefully slide the polycarbonate wall panels (Y1, Y2, Y4, Y6) into the assembled wall frames. Ensure they are properly seated and secured.
4. Assemble Top/Roof Structure: Construct the roof frame using components (L01C, L01D, L02C, L02B, L04A, L05B, L06C, L09C, L23E, D17, D26, Y3, Y7, Y8, Y9) and corresponding fasteners (S01, M01, Z08).
5. Install Roof Panels and Vents: Place the polycarbonate roof panels and assemble the adjustable roof vents (L11A, L12A, L19, L20, L21, A01, A03, Y10) as per the instructions, securing them with screws (Z02, Z04).
6. Assemble and Attach Doors: Assemble the left and right swing doors (D00R-L, D00R-R, L16A, L17, L18A, L18B, L18C, L18D, D45, Y11) and attach hinges (A51) to the main structure using screws (Z17, S27).
7. Install Accessories: Attach the gutter system components (J55, J56L/R, J94, J165, J166) and door hooks (J93, L25) and other accessories using the specified screws (Z02, Z08).

4. Operation

4.1. Doors

The greenhouse features two double swing doors for easy access. Each door is equipped with a latch for secure closure and a door hook to keep it open for increased ventilation when desired. Ensure doors are properly latched to prevent accidental opening, especially during windy conditions.

4.2. Roof Vents

The two roof vents are adjustable to four different levels, allowing you to control the internal temperature and humidity. Open the vents to release excess heat and moisture, and close them to retain warmth, particularly during colder periods. Regular adjustment based on external weather conditions is recommended for optimal plant health.

4.3. Water Collection System

The built-in gutter system directs rainwater from the roof to drainage pipes located at the four corners. You can connect these pipes to rain barrels or other collection systems to maximize water resource utilization for your plants.

5. Maintenance

• Cleaning Panels: Regularly clean the polycarbonate panels with mild soap and water to ensure maximum light transmission. Avoid abrasive cleaners or tools that could scratch the panels.
• Checking Seals: Periodically inspect all seals and connections for any signs of wear or damage. Apply silicone sealant as needed to maintain weatherproofing and insulation.
• Drainage System: Keep the gutter system and drainage pipes clear of debris (leaves, dirt) to ensure efficient water flow and prevent blockages.
• Frame Inspection: Annually inspect the aluminum frame for any loose bolts or signs of corrosion. Tighten fasteners as necessary and address any corrosion promptly to maintain structural integrity.
• Snow Removal: While designed for snow loads up to 18 psf, heavy snowfall should be gently removed from the roof to prevent excessive stress on the structure.
