The Right Drainage Management System
While drainage is often an overlooked component of the agricultural process for any greenhouse crop, managing drainage is actually a great way to grow better crops with fewer resources. Since growing in soilless media requires irrigating with drainage volume of 30% or more, reusing drainage can save you 30-40% on your fertilizer expenses and water use. Additionally, the drainage volume measurement is a great way to monitor and control irrigation. Measuring nutrient content in your drainage can tell you a lot about your plant uptake and how to tweak your plant nutrition plan.
That’s true for any crop, but medical cannabis drainage carries legal obligations. Because of its narcotic nature, drainage can’t always be conveniently flushed into a river. Legislation demands 100% water recycling for some facilities.
Drainage reuse, whether optional or mandatory, requires the right water treatment system. You can avoid spreading of pathogens with water treatment systems like the Netafim NUF system, and control the nutrient content in drainage with our ec/Ph monitoring and our nutrient systems.
