Walk-in Tunnel Greenhouse for Extended Growing

This white walk-in tunnel greenhouse provides a covered growing area for vegetables, herbs, flowers and saplings. The structure uses galvanised steel hoops and a reinforced PE cover to create a controlled environment that blocks UV while transmitting 85 percent of sunlight. It is designed for outdoor use to extend the planting season.

Upgraded Cover and Frame Replace Basic Cold Frames

The two-layer 140 GSM PE cover with a reinforcement grid resists tearing and maintains higher humidity than single-layer films. Galvanised steel crossbars, diagonal braces and a ground frame add rigidity compared with simple hoop houses. The jump is worthwhile when you need a durable, walk-in structure that can withstand wind levels of five to six.

Assembly by Two to Three People

The manufacturer recommends two to three people for assembly of the 11.4 foot by 9.8 foot frame. The sloped roof helps prevent sagging and improves stability, but the unit is not suitable for strong wind, heavy rain or snow. Replacement covers are available under SKUs 845-616WT and 845-616GN.

Questions about this item

How much ground space does the 11.5' x 10' frame require for anchoring?

The steel ground frame measures 11.4' long by 9.8' wide, so clear a level area at least that large before laying out the base rails.

Which step do people skip when assembling the galvanised hoops and crossbars?

The instructions call for 2–3 people; attempting the hoop-raising and crossbar bolting alone often leads to bent tubes or misaligned diagonal braces.

When the 140 GSM PE cover wears out, which replacement SKUs fit this tunnel?

Order cover 845-616WT for white or 845-616GN for green; both are sized to the 11.4' x 9.8' frame and attach to the existing ground frame clips.
