To raise awareness of what is best practice in terms of water use in hydroponic greenhouse cultivation Grodan and Priva have published the ‘Best Practice Guidelines for Greenhouse Water Management’. In their experience one of the main reasons why greenhouse growers hesitate to recycle drain water today is because they are worried about complications. Our water management guide is designed to remove these worries and to enable them to profit from the many advantages that are on offer. These include the obvious cost savings on the use of water and fertilisers as well as improving their environmental image when water discharge is reduced, which can be used positively in the company's marketing and communications.
Another step towards improving sustainability is crop growth optimisation which can be achieved by aligning irrigation and fertilisation with the crop's needs. This is called precision growing to gain more crop per drop.
This year the United Nations' World Water Day's theme is waste water. We need to start thinking of used water as a raw material rather than waste. It is plain to see that greenhouse cultivation is a frontrunner in this area when reusing water and fertilisers.
