FAQs

• What base/foundation is required?
  This polytunnel can be set up directly on grass, soil, or any flat surface—no permanent foundation needed. For maximum stability, use the included ground stakes and guy ropes.
• Is the unit weatherproof?
  The UV-resistant PE cover protects against sun, wind, and light rain. For severe weather conditions (heavy snow or storms), we recommend additional reinforcement or temporary removal of the cover.
• What are the maintenance requirements?
  The frame requires minimal upkeep—simply check fittings periodically. Clean the PE cover with mild soap and water as needed to keep it clear and effective.
