Been reading on aquaponics, it seems that it's quite expensive to mount the system, do you have anything in mind or it's just an idea so far? It does look quite awesome as a project and would provide really good content for STEEM xD If you were able to automate the whole thing it would be even better! I wonder if FarmBot could be programmed for that. Harvesting would probably be easier since no dirt would be in the way.
