Patriot Worm Tower - 5 Level System with Tea Collector

Patriot Worm Tower - 5 Levels

Patriot Worm Tower takes advantage of the natural tendencies of composting redworms to constantly eat upwards. Initially, Food scraps and worms are added to the lowest processing tray. As they consume, they leave behind valuable castings that are easy to access and harvest. These may be used directly on plants inside or in the garden, without the fear of burning roots or foliage. Additional trays with new scraps are added on top and the colony expands; the worms migrate up when they have finished eating the food in the lower trays. After all of the food has been transformed into castings in the lowest active tray, that level is emptied and placed on top with new scraps Ð maintaining a continuous processing cycle. Liquid effluent is constantly produced as a byproduct of food breakdown Ð the bottom holding tray collects this Ôworm teaÕ and can be used as a fertilizer or foliar spray on your plants, if diluted.Ê

Additional Comments: use top feed redworms only; avoid utilizing bottom feeding varieties in this system as they may clog up the collection level
