Kailan (Brassica alboglabra) adalah sayuran kubis-kubisan, mempunyai kandungan gizi dan nilai ekonomis tinggi. Permintaan kailan pada tahun 2012 sampai tahun 2013 terus meningkat yaitu dari 1.289 juta ton  menjadi 1.305 juta ton. Baby kailan yaitu kailan yang dipanen muda karena memiliki  bagian batang empuk, daun renyah, dan agak manis. Sistem hidroponik merupakan upaya peningkatan produksi kailan. Floating hidroponics system (FHS) adalah salah satu metode hidroponik dimana budidaya tanaman dengan cara menancapkan tanaman pada lubang styrofoam yang  mengapung diatas permukaaan larutan nutrisi dalam bak penampung. Electrical Conductivity (EC) dan pH mempengaruhi kecukupan serta ketersediaan unsur hara. Penelitian ini bertujuan mengetahui pengaruh variasi EC, pH  dan nutrisi terhadap pertumbuhan baby kailan menggunakan FHS. Metode percobaan yang digunakan Rancangan Acak Kelompok (RAK) dan data dianalisis menggunakan uji F. Perlakuan yang digunakan adalah EC 2,5, EC 4,0, pH 5,5, pH 7,0, nutrisi organik dan nutrisi anorganik. Parameter yang diamati adalah jumlah daun, tinggi tanaman, dan bobot tanaman. Hasil penelitian menunjukan bahwa jumlah daun tertinggi  terdapat pada kombinasi nutrisi anorganik EC 2,5 pH 5,5,  nutrisi anorganik EC 2,5 pH 7,0, nutrisi anorganik EC 4,0 pH 5,5, dan nutrisi anorganik EC 4,0 pH 7,0 berkisar antara 7,5-8,2 helai. Jumlah daun terendah diperoleh dari kombinasi nutrisi organik EC 2,5 pH 7,0 yaitu 3,6 helai. Tinggi tanaman tertinggi diperoleh dari kombinasi nutrisi anorganik EC 2,5-4,0 pH 5,5 berkisar antara 20,5 cm. Tinggi tanaman terendah terdapat pada kombinasi nutrisi anorganik EC 2,5-4,0 pH 7,0 dan nutrsi organik EC 2,5-4,0 pH 7,0 berkisar antara 11,5-12,6 cm. Bobot  tanaman tertinggi diperoleh dari kombinasi nutrisi anorganik EC 2,5-4,0 pH 5,5 sebesar 13,78 gram. Bobot tanaman terendah terdapat pada kombinasi anorganik EC 2,5-4,0 pH 7,0 dan nutrisi organik EC 2,5-4,0 pH 7,0 berkisar antara 5,0-6,4 gram.

Kailan (Brassica alboglabra) is vegetable type of cabbage, that has high nutrient content and high economic value. Kailan demand in 2012 until 2013 had been increased from 1.289 million tonnes to 1.305 million tonness. Baby kailan is kalian harvested at  young age growing because it has a soft stems, crisp leaves and slightly sweet. Hydroponic systems is an effort of increasing the production of kailan. Floating hidroponics system (FHS) a  method in which the plant cultivated by plugging the on the styrofoam hole that floats above the surface of nutrient solution in the tank. Electrical Conductivity (EC) and pH affect the nutrient availability. This study was aimed to determine the effect of variations in EC, pH and nutrients on the baby kailan growth under FHS.  This experiment used a randomized block design (RCBD) method and the data were analyzed using the F test. The treatments used were EC 2.5, EC 4.0, pH 5.5, pH 7.0, organic nutrients and inorganic nutrients. Observed parameters are number of leaves,  plant height, and weight of plant. The research result showed highest number of leaves was found in combination  inorganic nutrients EC 2,5 pH 5,5, inorganic nutrients EC 2,5 pH 7,0, inorganic nutrients EC 4,0 pH 5,5, and inorganic nutrients EC 4,0  pH 7,0 ranged from 7,5-8,3 strands. The lowest number of leaves was obtained from the combination of organic nutrients EC 2,5 pH 7,0 namely 3,6 strand. The highest plant height was obtained from the  combination of inorganic nutrients EC 2,5-4,0  pH 5,5, ranged from 17-21 cm. The lowest height plant was found in the combination of  inorganic nutrients EC 2,5-4,0 pH 7,0 and organic nutrients EC 2,5-4,0  pH 7,0 ranged from 10-12,6 cm. The highest weight of  plant was obtained from the combination of  inorganic nutrients EC 2,5-4,0  pH 5,5 namely 13,783 gram. The lowest  weight plant was obtained from the combination of inorganic nutrients EC 2,5-4,0 pH 7,0 and organic nutrients EC 2,5-4,0 pH 7,0 ranged from 5-6,4 gram.
