Hey @jthornton I repourpoused my winter duck pond cover into a garden bed to plant wheat seed in so the dux can eat the sprouts kinda like what you do. They will love it if it grows!
I don't think I got enough Dirt in it though. The sprouts will have to get fairly tall before they can reach it. I'll see how it goes I may have to add more
I just used regular grass seed in my grass boxes.


I tried wheat grass once but it didn't do too well... but that might have been something I did wrong.
