FIM Cannabis Training Explained (Part 2): How to Perform a Perfect FIM Cut

In Part 2 of our FIM series, we move from theory to practice. Learn exactly when to perform a FIM cut, which plants respond best, how to identify the correct growing tip, and why removing approximately 70–80% of the apical meristem gives you the best chance of success. We'll also cover the most common mistakes growers make, why FIM is less predictable than topping, and how genetics, plant vigor, and environmental conditions influence the final result. By understanding the science behind the technique, you'll know when FIM is the right choice—and when another training method may produce more consistent results.
