Hydroponics is the science of growing plants in a medium without soil, using mixtures of the essential plant nutrient elements dissolved in water. There are several advantages in hydroponics culture such as, no cultivation, no weeds, cleanliness, no toxic substance, uniform and high yield etc. This study is conducted on growing coriander and chinese kale in the solution which was found in 1995. The solution formula is folia fertilizer, 21-21-21 and micronutrient fertilizer with the concentration of 250 and 125 ppm, respectively. Also, and 0.03 M Na Fe EDTA solution 0.05 ml per litre culture solution every two days in both circulated and deep water media solution system. The objectives of this study are to find out the technique for growing coriander and chinese kale and the income from these growing. The result are:- Both, coriander and chinese kale suitable for growing on deep media solution system. Coriander could not grow on circulated media solution system. The income from growing coriander on deep media solution system is approximatly baht 187,482 a rai a crop (40 days). The profit is baht 76,390 a rai a crop (40 days), if sale baht 200 a kg. Chinese kale, the income from growing on deep media solution system is approximatly baht 343814 a rai a crop (40 days), the profit is baht 258,178 a rai a crop (40 days), and on circulated media solution system is approximatly baht 138,282 a rai a crop (40 days), the profit is baht 61,892 a rai a crop (40 days), if sale baht 50 a kg. It is possible to growing chinese kale in both deep media solution and circulated media solution systems. It give high income. Coriander can grow only on deep media solution system and the yield slightly to low. It is need to improve techniques in growing and transfer seeding of coriander for both deep media solution and circulated media solution systems for a higher yield production.
