Greenhouse Aquaponics: DIY system to farm fish with vegetables
In this video, Rob Torcellini shows us the aquaponics greenhouse in his Connecticut backyard.
Rob bought a $700 greenhouse kit to grow more vegetables. Because he had a mosquito problem, he decided to add fish to get rid of them. Since then he has become a committed aquaponic gardener, with an abundant greenhouse filled with vegetables and fish. And in true permaculture fashion, the fish poo fertilizes the garden. Rob has even built a system for inside his home that grows lettuce above a fish tank.
Aquaponics combines fish farming (aquaculture) with the practice of raising plants in water (hydroponics). It's organic by definition: instead of using chemical fertilizers, plants are fertilized by the fish poo (and pesticides/herbicides can't be introduced to kill pests because they could harm the fish). Since the plants don't need dirt, aquaponics allows gardeners to produce more food in less space. And in addition to the vegetables they can grow, most aquaponics gardeners cultivate edible fish as well.
