Further along on the pondering road......
Think I can make some large (about hay bale size or large cooler size) SOLID blocks to use like cinder blocks to surround my raised beds????
IF I can figure out what to mold them from (might have to hack one together out of lumber) maybe I could build interlocking ones.......Hmmmmmm.
My mind is a more agile builder than my actual building skills are.
Or maybe I could just place my bales doublewide with a space between to line with plastic and fill with hypertufa and then remove the outer bales after it's cured. Hmmmmmmm,,,,,
