Step 4: Construct the Roof Frame
- Build a sloped roof (angled at 35-45°) using wood or metal beams.
- Cover it with polycarbonate panels or greenhouse plastic for light penetration.
- Leave a ventilation gap or install vents to control humidity.
Step 5: Insulate and Secure the Greenhouse
- Use earth berming (pile soil against the outer walls) for extra insulation.
- Install thermal mass elements (barrels of water, rocks, or bricks) to absorb heat.
- Seal doors and windows tightly to retain warmth.
Step 6: Set Up Planting Beds and Irrigation
- Use raised beds or direct soil planting.
- Set up drip irrigation or rainwater collection for efficient watering.
- Add compost or organic soil amendments for fertility.
Step 7: Maintain the Greenhouse
- Regularly monitor temperature and humidity levels.
- Adjust ventilation to prevent mold or overheating.
- Rotate crops seasonally for continuous production.
