Rainwater Collection for Cannabis Cultivation

    Rainwater Harvesting

    Rainwater harvesting utilizes a building rooftop to convey rainwater into storage for later use. The land that buildings have a foundation on is an impervious surface because water cannot pass through it to get to the ground. Roads, sidewalks, and general development increases impervious surfaces that can lead to more flooding since rainwater cannot pass to the ground.


    When rainwater is collected and stored safely for later use, it prevents this wasted water runoff that can’t pass through the impervious cover. This sustainable water cycle is a more direct water source than using a utility water source and reduces water waste.


    Rainwater harvesting systems range from using your existing gutter system to channel the rainwater into a barrel to a large scale commercial system that can supply enough water to make a huge difference in water use. Rainwater is considered to be a perfect water source for cannabis cultivation since it typically has a nearly neutral pH with less contamination than the average utility water source.

    The Endless Advantages of Rainwater Harvesting

    Rainwater harvesting as a sustainable water source:

    – Saves money on water purchasing through a utility or other water source

    – Reduces demand on the municipal water supply

    – Reduces flooding, erosion, and contamination of surface water with contaminants

    – It provides a clean, pH balanced water source that is free of salts and other minerals that can harm plant root growth.
