This family converted an unused swimming pool into a greenhouse that grows produce tilapia fish, and chickens for eggs. Pretty ingenious. (There must be some mistake though, why would rainwater go with gray water?)
These folks feed their family with a garden in their swimming pool — and you can, too
Instead of commercial fertilizer, chicken droppings fall through wire mesh strung across the pool’s deep end, nourishing the algae & duckweed in the pond below. The tilapia eat the pond plants, release their own nitrogen-rich excrement, & the fish water then gets funneled (using a solar-powered electric pump) into the hydroponics system that grows the family produce.
Perpetual Harvest Greenhouse provides an indoor ecosystem capable of growing equal yields of organic produce year around. This system creates ideal growing days by optimizing light, carbon dioxide enrichment, and soluble nutrients in conjunction with continuous planting and harvesting. Because the geo-hydroponics can economically simulate warm season growing conditions, crops that would otherwise be shipped from warmer climates can be grown profitably in colder climates during winter months.
