The purposes of this research were to determine the effect of giving organic nutrition, a combination of moss extract + chicken bone flour + coconut fiber ash with a variety of Ec on the wick hydroponic system and determine the best organic nutrition to the wick hydroponic system for pakcoy. This research was arranged on a CRD (Completely Randomized Design) with single factor, consists of 6 treatments: AB mix Nutrition, organic nutrition Ec = 1, organic nutrition Ec = 1.25, organic nutrition Ec = 1.5, organic nutrition Ec = 1.75, and organic nutrition Ec = 2. Each treatment consisted of 3 replications, totaling 18 samples. The results showed that the use of organic nutrition for wick hydroponic system has an effect on the growth and yield of pakcoy. The use of organic nutrients with Ec = 1 mS / cm gave the best growth and yield.
