Dimensions & details

• Dual-layer zippered doors: PE cover door and inner mesh door create flexible access for early spring use, allowing ventilation with insect protection by day and improved wind resistance and warmth when fully closed.
• Advanced wind reinforcement: V-shaped diagonal bracing, reinforced corner door posts and an added steel wire along the roof help reduce frame movement, achieving wind resistance up to level 5–6 when properly anchored.
• Adjustable mesh ventilation: Eight mesh windows with roll-up covers and tie straps provide controlled airflow, helping regulate humidity and temperature without exposing plants to sudden cold gusts.
• Ground-level sealing and anchoring: 15cm extended ground skirt works together with guy ropes and ground stakes to reduce draughts at soil level and improve overall stability in windy conditions.
• Durable roof construction: 140gsm PE mesh cover with PVC-coated polyester edging and heavy-duty No.8 zips improves wear resistance at stress points, making this tunnel suitable for repeated early spring and seasonal use.
