Extend your favorite season — the gardening season! — with our Aggie Cold Frame Box. Crafted from beautiful cedar wood, supported by powder-coated steel accent legs, and boasting a double-wall polycarbonate lid and interior liner, your plants will be protected from wind, cooler temperatures and first frost. It also features an innovative electricity-free, temperature-activated hinge on the lid that will automatically open to vent the box when the inside temperature gets too high. And as the temperature drops the lid will automatically close. Now, you can harvest later into autumn and early winter, then plant and harvest earlier in spring. With the Aggie Cold Frame Box, you can make the growing season itself grow!
