From our test beds

Honest note: on a sunny winter day a closed tunnel can cook to summer temperatures. Vent the ends when the sun is out, or you will bake the greens you are trying to protect.

FAQ

Questions, answered

Does row cover need to come off to water?

No — the fabric is permeable, so rain and irrigation pass right through. Vent it on warm sunny days so plants do not overheat.

Can it stop a hard freeze?

It buys a few degrees, good to about 28°F. For a deep freeze, double the layer or add a second cover.

The long read

Why we grow it this way

Steal weeks from both ends of the season

A few degrees of frost protection is the difference between a garden that quits in October and one that keeps going into December. This kit gives you ten galvanized hoops, twenty feet of row-cover fabric, ground staples, and a soil thermometer — enough to build low tunnels that hold off frost to 28°F while letting light and rain through.

Start earlier in spring, harvest later in fall, on the same beds.

Greens into December

Threw the tunnels over my spinach and kale and kept harvesting past the first frosts. Hoops are sturdy and reusable.

Works, remember to vent

Great for spring starts. Learned quickly to open the ends on sunny days after cooking a row of lettuce.
