Extend the Growing Season

This mini tunnel greenhouse protects plants from cold, rain and snow so you can grow longer. The two-layer 140 GSM PE cover has a reinforcement grid to resist tearing and lets 85% of sunlight through while blocking UV scorching. Four-inch extended stakes can be buried to tighten the cover against wind.

Replaces Temporary Covers

Unlike loose plastic sheeting or cold frames without ventilation, this structure adds roll-up zippered doors and two mesh windows for airflow and easy access. The steel frame and ten ground stakes anchor the unit firmly in soil. The jump is worth it when you need a stable, walk-in space that stays put through a season.

Suits Seasonal Gardeners

Gardeners who want a portable warm house for seedlings and potted plants will appreciate the 5.9' L x 4.6' W x 2.6' H interior. Assembly is required and the cover is polyethylene, not polycarbonate. Buyers who need a permanent glazed structure or a larger walk-in greenhouse should look at something else.

Questions about this item

How much ground space does the 71" x 55" steel frame need for the ten stakes?

The frame measures 5.9 ft long by 4.6 ft wide; the ten included stakes anchor through pre-made edge holes, so clear a level patch at least that large before assembly.

What is the trick to tensioning the 140 GSM PE cover so it resists wind?

After sliding the cover over the steel arches, bury the 4" extended stakes in the soil and pull the hem tight; the internal reinforcement grid stops tearing while the tension keeps the cover from flapping.

How often should the two-layer PE cover be replaced under normal sun exposure?

The 140 GSM polyethylene with UV protection typically lasts two to three growing seasons before brittleness reduces the 85% light transmission; keep spare cover dimensions handy for a quick swap.
