Walk-in Greenhouse for Extended Growing

The tuphen white steel trellis creates an 8' by 5.9' by 7.5' covered space for fruits, vegetables, herbs and flowers. Its powder-coated steel frame resists water and warping while the 140 GSM PE cover transmits 85% of sunlight and blocks UV. Twelve ground stakes and four guy ropes anchor the structure against wind.

Ventilation Limits With Roll-up Panels

Six roll-up windows measuring 24 by 27.5 inches and two zippered doors sized 35.5 by 71.75 inches provide the only airflow control. Heat and humidity can be vented slowly through the windows or rapidly through the doors, but there are no powered fans, louvres or automated climate systems. The 6-inch buried skirt helps shed rainwater yet does not eliminate pooling on level ground.

Replaces Cold Frames and Row Covers

This walk-in enclosure upgrades from low tunnels, cold frames or temporary row covers by offering standing-height access and a larger protected volume. The jump is worth it when you need to tend plants daily, start seedlings earlier in spring or keep tender perennials alive through frost. It does not replace a glazed greenhouse with heating, insulation or automated environmental controls.

Questions about this item

How do I decide whether the 8 ft length and 5.9 ft width suit my garden space?

Measure the intended footprint; the greenhouse occupies 8 ft by 5.9 ft at ground level, so allow extra clearance around all sides for staking and access.

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

The 140 GSM PE cover lets 85 % of sunlight through while blocking UV, giving most vegetables and herbs strong light without scorching.

How does the steel frame and PE cover perform in wind and rain?

Powder-coated steel resists rust and warping, and the tear-resistant cover with 6 in buried edges sheds rain and handles moderate wind when all twelve stakes and four guy ropes are secured.
