This morning I have been to view some land that already has tanks on that I'm considering renting to put a small commercial aquaponics set up on here in Thailand.

As you can see from the images the owner has already built four good size tanks under cover which are roughly 328x465x88cms (WxLxD) and there's land for poly-tunnels which measure 15.25x30.5m.

I could do with an idea of how many lets say lettuce I could grow and how many fish the tanks would hold so I can start costing it up. I think I'd start with barrelponics to keep costs down. Any other thoughts on this from you guys would also be appreciated.

Thanks for looking!
