We developed an greenhouse-based aquaponics system in partnership with Seed Aquaponics. The system is 2-tiered, warmed by ambient greenhouse heat and used to grow more sensitive seedlings, while raising winter-hardy fish crops for consumption by farmers/interns, etc. The water is collected rainwater that comes off the shed and greenhouse and flows into the system. We have a filter barrel at end of system to catch large portion of nutrient-rich solids and every 2-3 months we drain barrel onto greenhouse planting beds!
The video gives you a brief introduction to our system.
