We used our 200 pounds to buy a cold frames. We didn’t get one of line. Somebody made it for us because the ones on line could not handle the wind. Somebody made is wind prof and it is rose its easy to move around. You can put trays in and also just have some soil in the bottom of the cold frames and put some plants in the bottom and in the trays. This is going to be very useful for when we are growing plants that need to be in hotter places.
