My Mom was visiting a couple of weeks ago and the conversation turned to aquaponics. Naturally. Turned out she'd had plans to do a garden this year, but her yard space got pre-empted by recession-related events in the lives of relatives. But she still has full use of her 10'x12' greenhouse.
By the end of the weekend, I'd set her up with bell siphons and lots of information. She's started her own blog over at utahponics.blogspot.com, should you wish to see how she's doing things.
She liked my rubbermaid stock tanks, but already has a bunch of sturdy bins that might work, plumbed together in series. Also, she lives in a climate where termites and moisture are less problematic, so she can consider using wood in the structure of her tank and beds.
She also has a surplus swamp cooler, so is considering doing cold-water aquaponics (trout and 'cold weather' vegetables). Pretty fun!
