Runoff is the excess water that flows over the surface of the soil after irrigation or rainfall, often seen in cannabis cultivation.
Also called / Category:
Overflow / Environment, Media & Nutrition
Key takeaways:
- Runoff helps measure nutrient levels in cannabis cultivation.
- Ensures proper drainage and prevents waterlogging.
- Can lead to nutrient leaching if not managed properly.
What it is / How it shows up:
Runoff is commonly noted in cannabis growing guides and forums. It refers to the surplus water that drains away from the soil after watering plants. In cannabis cultivation, runoff is crucial for understanding soil nutrient levels and ensuring plants receive adequate hydration without waterlogging. Proper management of runoff ensures excess salts and nutrients are flushed from the soil, maintaining a healthy growing environment.
How it’s measured or identified:
- Collected in trays or saucers under pots.
- Measured by the volume of water collected after irrigation.
- Tested for pH and nutrient levels using meters or test kits.
Use in context:
- "Collect the runoff to test nutrient levels in your soil."
- "Ensure your plants have adequate runoff to prevent root rot."
- "Monitor runoff to avoid nutrient buildup in the medium."
Safety & compliance in Canada:
- Ensure runoff does not contaminate local water sources.
- Dispose of runoff responsibly to comply with environmental regulations.
