This is my experimental vermiponics flow-through system. A solar-powered pump pulls water up to the top planter from the red basin below. Hydroponic tubing trickles the water into the buckets below, until reaching the grey bucket near the bottom, which contains about 1.5 pounds of red wiggler composting worms. Small holes in that bucket let the water fall back down into the red basin, which contains a few guppies to eat mosquito larvae. I don't feed them, but I do put kitchen scraps and rabbit poo into the top of the grey bucket holding the worms.
