Abstract: 
This research aimed to know the effect of the type of growing media and population density on the growth and yield of kailan (Brassica oleracea L.) hydroponically. The research was conducted in the greenhouse of the integrated agricultural system area at Curug Serang Banten Province. This research used a Randomized Completely Block Design (RCBD) as factorial with two factors. The first factor was the type of growing media (J) which consisted of 3 levels, J1 (Rockwool), J2 (Zeolite), and J3 (Sponge). The second factor was population density (K), which consisted of 3 treatment levels, K1 (3 plants per tub), K2 (4 plants per tub), and K3 (5 plants per tub). The results showed that the type of growing media had a significant effect on plant height growth 7 Day After Plating (DAP) of (4.67cm), 14 DAP (11.58 cm), 21 DAP (17.09 cm), 28 DAP (22.29 cm), 35 DAP (37.57 cm), number of leaves 14 DAP (4.59), 28 HST (6.96), 35 DAP (8.59) and the root weight of your plants was 35 DAP (3.43gram). Population density treatment had a significant effect on plant height growth 28 DAP (22.26 cm), 35 DAP (37,37 cm) and there was an interaction between media type treatment and population density on plant height parameters 35 DAP.
