I have modified cold frame. When the weather is cold, and the sun is shinging, I don’t want to have to go outside to see if there is too much heat building up or something.
So I put raised beds next to a retaining wall for the back, fill milk jugs with water along the sides, and the front faces south west. Then I cover the bed with a row cover and weight it down with wood we have for the fireplace.
If needed I put anouther layer of row cover and/or straw. I only go out to harvest or take the cover off during nice sunny days with mild temps.
The row covers let in light and rain. Lazy daisy gardening.LOL.
What are you growing in there?
