In the Netherlands, rainwater is the preferred choice for greenhouse irrigation

Heard of WUR? It stands for Wageningen University & Research and includes the Dutch national research center 100% committed to researching in the area “healthy food and living conditions”. One major WUR statement to remember is “Rainwater is the only suitable source of irrigation water”. It’s clean and consequently doesn’t need any treatment before use for irrigation. In countries where annual rainfall is low, disinfecting and reusing irrigation water is needed.
