Flushing Schedule Guide for Soil and Hydroponic Cannabis

Understanding the Importance of Flushing in Cannabis Cultivation

Cannabis flushing is a critical stage in the growing process that helps prepare plants for the final harvest. During flushing, growers aim to reduce nutrient levels and flush out excess salt build-up. This is essential for both soil and hydroponic systems, ensuring plants have a cleaner and healthier start when entering flowering.

Cannabis Flushing for Beginners: Step-by-Step Guide

Flushing Schedule for Soil-Cultivated Cannabis

• Day 1-5: Start the flushing process by gradually reducing your nutrient solution strength.
• Day 6-10: Continue reducing nutrient levels while maintaining optimal pH levels (around 6.2-6.4).
• Day 11-15: Stop using nutrients completely and ensure water pH remains consistent.
• Day 16: Prepare your flowering phase nutrients or begin your final flowering stage with standard nutrient levels.

Flushing Schedule for Hydroponic Systems

• Day 1-3: Decrease your nutrient feeding rate by 20%.
• Day 4-6: Lower nutrient levels by an additional 20%, continuing to maintain consistent pH levels.
• Day 7-10: Flush your plants with pH-neutral water or a flushing agent, ensuring to top off the system if needed.
• Day 11: Switch to your final flowering nutrient mix, adjusting feeding to normal rates.
