Extend your growing season with Backyard Discovery's Aggie Cold Frame Planter Box. This mini greenhouse is ideal for keeping your plants protected from harsh weather while creating a thriving environment for growth. The innovative temperature-activated hinge automatically opens the lid when it gets too hot and closes as temperatures drop, maintaining optimal growing conditions for your plants, flowers, and veggies. The lid features double-wall polycarbonate panels to ensure excellent light transmission while providing superior insulation for your garden. Built from solid cedar wood with powder-coated steel legs and hardware, this cold frame greenhouse offers lasting durability and exceptional resistance to rust. Wide bottom slats and a heavy-duty mesh liner provide proper drainage to nurture healthy root development. This portable greenhouse combines the benefits of a raised garden planter with cold frame protection, offering plenty of growing space in a compact design. Perfect for homes with limited space, its thoughtful design makes it easy to position anywhere in your backyard. The cold frame comes ready to assemble with pre-cut and pre-drilled components, making setup a breeze. Backed by a 5-year warranty, this mini greenhouse helps you nurture seedlings, plant earlier in spring, and continue growing through the winter for year-round gardening.

Ellie ★★★★★

The lid props open on its own so I don't have to hold it while watering, which sounds small but matters when you're crouching in the yard. My lettuce seedlings have stayed warm and untouched through two nights of frost already.

Timothy H. ★★★★★

Kept my kale going through the first frosts when my raised beds were done for, which is exactly what I bought it for. The lid opens and stays put on its hinge so I can vent it on warm afternoons without fighting with it.

Harper ★★★★★

I started lettuce seeds in this in early March and they were ready to transplant weeks before my neighbors' seedlings. The frame traps heat really well even on frosty mornings, and my spinach has never looked better.
