Ideas For Keeping USFG Raised Bed Warm In Winter
I'm growing my first winter garden after building a Ultimate Square Foot Garden Raised Bed. To hold the greenhouse fabric in place I tried some stainless steel tablecloth clips that are meant to be used on picnic tables but they're not working out.

The slide off and leave the plastic flapping around allowing cold air to come in.

There was a quick solution to that problem which creates a much better air seal and I have an idea for an easy way to provide some additional heat which won't cost a lot of money.
