Summer and hydroponics: what to do during the hot days?
This is an important question, knowing that a successful hydroponics operation relies on good oxygenation of the root mass, and that oxygenation and temperature are closely linked… Indeed, hydroponics is a growing method that relies upon a dynamic flow of water saturated with oxygen. But the higher the temperature, the less oxygen will remain in your solution and in summer, when outside – and room – temperatures climb up to 30 and 40°C, then it is time to start worrying. With high temperature and little oxygen, your roots will start to deteriorate, and soon pathogens will develop. These are the basic conditions for insects and fungi to thrive on weakened individuals with no or hardly any defences left. If you are not careful, or if you don’t know how to do it, you may loose some plants or even a whole crop.
