I didn't get the cinderblock bed finished, but I did the white floating row covers "elevated" a bit so they aren't sitting right on the seedlings underneath.
Floating row covers are merely a type of gauzy spun-fiber cloth that is very light, allows light and water to go through but keeps bugs and frost off. During the day, when it's sunny, I fold them off to the side in order to allow the soil to warm in the sun.
I can't wait to see that garden bed in April, chica.
