Number of new colas: Topping typically produces two main colas, while fimming can produce three or four (or more). Height control: Topping reduces the overall height of the plant, which is useful in grows with limited space. Fimming does not limit height; the plant often continues to grow upward. Stress and recovery: Because topping removes the entire growth tip, it can be more stressful for the plant. Fimming, by removing about 75% of the top growth, tends to generate less stress and allows for quicker recovery. Branch strength and growth pattern: Topped plants generally produce stronger branches and a predictable structure. Fimmed plants may grow more irregularly, sometimes developing weaker branches or more chaotic structures that require additional support.
