Welcome Sylvia, interesting timing as I'm leaving tomorrow for a aquaponics construction course with Murray Hallam in Oregon. Just a quick question? Have you done any experimenting with homemade fish food. I'm thinking one could reduce costs be examining the diet of the species chosen then providing soldier fly larva, insects, duck weed, worm castings, veg scraps ect.
How about excavated greenhouses? I'm in Canada and planning to incorporate aquaponics into the greenhouse of the future. Thanks for your time. I'm looking forward to all the questions and responses.
