As long as the concrete slab(?) is high enough above the surrounding ground,Yes let me clarify I don't have a picture yet as the raised bed is stored inside since I don't have a roof built yet, but basically it's just a simple raised bed with a plywood bottom over concrete. We built it with 2x6's expecting to use sand, I'm guessing bedding might need something deeper as it will take up much more room. We are planning on building a roof/shed around the whole thing for weather/security purposes so rain drainage is really not too much of a factor for us, but could certainly be for a lot of people.
I'm in Central Illinois area, have added to profile, thank you for showing me how!
drainage shouldn't be a problem.
Not sure why you'd need a plywood bottom tho.
