How does the Wilma 8-Pot system work? Wilma recirculating systems consist of a nutrient reservoir, a top tray that holds the pots and a dripper system that feeds nutrient to the pots everytime a timer turns on the water pump. The top tray is designed to drain the nutrient back to the reservoir after every feeding. Nutrient is recirculated and should be completely changed every 7-10 days. The system comes with two full sets of drippers, one is a free flow dripper for use with clay pebbles and the other is a 2lph dripper for use with CoCo or soil.
