This time of year, I’m getting ready for fall and winter, planting brassicas and garlic.
Here’s what I do.
The glass or plastic insulates the bed, too, so it stays much warmer than the surrounding area.
The arm actually works via an internal piston that is surrounded by wax.
The wax expands when heated, forcing the piston to activate the arm.
Cold frames are asimple build, which means you might easily make them custom to your raised bed.
Thearticulating window armscan be bought on Amazon.
Of course, you’ve got the option to also buy cold frames, pre-built.
You want to be sure they fit the size of your raised beds.
These work a lot like popup tents, except that they are see-through and lower to the ground.
In fall, the popup goes over one of my raised beds.
Unless that greenhouse is bolted down, it will take flight and youll spend your winter chasing it.
The popup usually comes down before the first big windstorm, and folds up for next year.
Even before a major windstorm, I would avoid tall, walk-in popup greenhouses.
The ones that work are close to the ground, no more than 40 inches tall.
A hoop is erected every few feet over the row, creating a tunnel.
Building low tunnels by hand in a raised bed is as simple as bendingPVCover the bed.
Most kits are flimsy, which is why ultimately PVC is a better solution.
In either case, I always keep a smart temperature reader in my greenhouses and cold frames.
