Planting of kale
How to plant hydroponic kale next is to prepare the seeds well. For this stage, the thing you need to prepare is not only the nutrient content in the solution but also the quality of the seed. Once the seed is ready, put the seed on a used tin of paint that has been filled with water. Not just left alone, make sure also that the root of kangkung planted touch the water. However, do not let the stems sink in the water so that it remains above the surface. The sinking rod will make the kale plant rot. When the kale is already visible leaves, you dispose of water contained in the paralon then replaced with a solution containing ABmix 400 ppm nutrients.
