Introduction
Adjusting the pH of your cannabis grow medium is crucial for maximizing plant health and yield. Here's a guide to help you achieve the perfect pH for your cannabis.
Understanding pH
Potassium hydroxide (KOH) and phosphoric acid (H3PO4) are commonly used to adjust pH levels. It's important to maintain a pH range between 5.5 and 6.5 for optimal nutrient absorption.
Testing pH
Use a pH meter or test strips to measure the pH of your water and grow medium. This will help you identify if adjustments are needed.
Adjusting pH
To lower pH, add phosphoric acid. To raise pH, add potassium hydroxide. Be cautious with these chemicals and follow the instructions carefully.
