[Vault Hunters] Create Crop Farm

After putting off getting more chromatic iron thinking I'd find plenty more in the vaults, I finally went mining the other day so that I could get going with create. I was a bit disappointed (but not surprised) to find that minecart assemblers were removed from VH, but I managed to get this thing working after playing with it a bit (hadn't messed with gantries previously).

Before I fill the rest of the farm, are there any other crops that I could farm with this contraption with little to no modification that would be useful? I'm mainly thinking of altar recipes, but other uses would be good too.
