Walk-in Greenhouse for Extended Growing

This 13' x 9.7' x 6.5' tunnel greenhouse provides walk-in space for vegetables, herbs, flowers and saplings. The 140 GSM PE cover blocks UV while transmitting 85% of sunlight to protect plants from scorching. A reinforced grid within the two-layer cover helps prevent tearing and maintains high humidity. Galvanized steel hoops and crossbars form an arch that resists sagging and adds stability.

Windproof Rating and Weather Constraints

The structure carries a windproof level of 5 and is not suitable for strong wind, heavy rain or snow. Two zippered mesh doors measure 63" wide by 67.75" high for access and ventilation. Ten mesh windows allow fresh air circulation while keeping insects out. Burying the 7.75" extended edges in soil tightens the cover against wind uplift. Assembly is recommended for two to three people.

Upgrade from Cold Frames and Row Covers

This greenhouse replaces smaller cold frames or row covers when a grower needs standing-height space and full-season climate control. The jump is worth it for gardeners who want to start seedlings earlier, protect tender perennials through winter, or cultivate heat-loving crops without a permanent glass structure. It does not suit growers who require a snow-load rated building or a frame rated for high-wind zones.

Questions about this item

Should I choose the 13' x 9.7' tunnel or a smaller greenhouse for my garden?

The 13-foot width and 9.7-foot depth create a large walk-in grow space that fits multiple raised beds or rows of vegetables, herbs and saplings, so pick this size if you need generous headroom and floor area for a full-season nursery.

What does the 85% sunlight transmission mean for plants inside?

The two-layer 140 GSM PE cover lets in 85% of nourishing sunlight while blocking UV scorching, maintaining high humidity and protecting seedlings from leaf burn during long summer days.

How does the zippered mesh door and window system work in practice?

Two roll-up doors measuring 63 inches wide by 67.75 inches high and ten mesh windows provide easy access and cross-ventilation, keeping insects out while allowing fresh air to circulate and excess moisture to escape.
