Hydroponics is an agricultural system because it can be cultivated in various places, such as villages, cities, open land, and apartments. A hydroponic system can be used throughout the year, regardless of the season. In this study, 4 types of nutrition were used, namely cabbage leaf bokashi, chicken manure bokashi, combination of chicken manure bokashi with cabbage leaf bokashi, and AB Mix nutrient solution. Bokashi is a Japanese word that means fermented organic matter, a process that converts food waste and similar organic matter into a soil amendment that adds nutrients for the plants. The AB Mix solution was prepared by mixing 83 grams of AB Mix A and 83 grams of AB Mix B and letting them dissolve in 2 liters of water. Vegetables are in great demand by the public because they have high nutritional content and are beneficial to health. One type of vegetable that is needed by almost everyone is red lettuce (lactuca sativa var. red rapids). Almost all types of plants can be grown in a hydroponic farming system. The purpose of this study was to determine the growth of red lettuce using AB Mix solution in comparison with the three types of bokashi solution, by measuring the width of the leaf and the length of the plant roots. The experiment was tested by Anova and Duncan analysis with a level of alpha of 0.05. The result of the experiment is that the use of AB Mix solution has the best plant growth in comparison with the three bokashi solutions.
