These hydroponics systems are set up to grow plants on worm tea. This process is called vermiponics. These systems were designed by Ed Meisel to utilize low-cost materials efficiently. These hydroponics systems have grown up to 300 lbs of tomatoes at one time. We are currently experimenting with using worm tea as the sole nutrient source for plants.
Vermicast (the solid waste from vermiculture) is also used to grow plants throughout the greenhouse.
All of the plants in the greenhouse are grown using vermicast and worm tea--all from waste that is typically thrown away.
