Hydroponics is fancy name for growing plants in soilless media with a nutrient solution. Humans started dabbling in hydroponics as far back as 1670 when it was discovered that plants grew better in ‘dirty’ water than in distilled water. Hydroponics became a great way to identify the essential nutrients for plant growth, and the minimum and maximum levels required. Hydroponics gives complete control on nutrient availability.
In Kenya hydroponics is relatively new, becoming popular in the last 15-20 years. The initial move from soil to hydroponics was prompted by the banning of the soil fumigant, methyl bromide, and a general decline in production over time in plants grown in the same soil. It was soon discovered that managed well, hydroponics could be more productive, with better quality and less disease pressure. Hydroponics is generally restricted to high value crops, like roses, but more and more we are seeing tomatoes, capsicum, herbs, leafy vegetables and summer flowers in hydroponics.
