This is the lettuce patch. It also serves as a cold frame. The cinder blocks absorbs the heat from the sun and slowly warms the soil during the night during the cold months. A simple plastic sheet is all that is needed over the top.

We have lettuce, swiss chard, spinach, radishes and a planting of peas. The lettuce is wilting now. The temps are reaching in the 80's.

I plan on attempting a shade tarp to keep the temps and sunlight down on the lettuce, swiss chard, and spinach.

We plan on planting carrots in the next few days.
