I could throw some 2x4s in. That means removing all the rock and stuff. If I did it all over again I would. Moving the standpipe took about 5 minutes, so it was easy.

I think I will go with a wicking bed on the left side. That will make starting seeds easier and I know some stuff just grows better in soil. It would be cool to have both types going.

I want to put a small raft in on the water also for lettuce. Apparently, that's the ways to go for lettuce.
