Fimming vs Topping: Which is Better?

Fimming and topping cannabis plants are both cutting methods used by cannabis growers to improve the shape of the plant (so they can better access light), induce the growth of more colas (flowering sites) and, ultimately, harvest bigger yields. But which is the best method for training your plants? Here we will go over the pros and cons of each technique to help you make your decision.

Topping is better for:

  • Beginners
  • Controlling the shape of your plant
  • Prettier plants

Fimming is better for:

  • Small-scale growers
  • Producing more colas
  • Causing less stress to your plants

What is ‘Fimming’ and ‘Topping’?

Both of these techniques are essentially methods of pruning your cannabis plants in order to get bushier plants and better results come harvest time. Topping and fimming are known as ‘high-stress training techniques’ (HST) and are often used in indoor growing as a means of helping plants make the most of the light source.
‘Topping’ refers to the technique of cutting off the top of the plant in between the nodes. On the other hand, ‘Fimming’ is the process of removing new growths but avoiding cutting between the nodes. While pretty similar, these techniques do produce slightly different effects and often growers have a preferred technique.

What are the Pros and Cons of Topping?

Topping is the recommended HST for those that are beginners to growing as it is very easy to undertake and will give you some great results. All you need to do is wait until your plant has grown a minimum of 3 nodes and then cut off the newest node – cutting just above where the leaves of the node underneath are. This will lead to 2 colas growing in the place of the 1 you cut off – giving you 2 for the price of 1!
This is a quick and easy technique which will not only increase the number of colas you produce but also help your plant to grow bushier and healthier. Topping will also help to control the shape of your plants, making them less like a Christmas tree and more able to be exposed to more light – this is especially important if you are growing indoors to make the most of your grow lights.
This is a pretty successful technique but the one con of topping is that it might take a bit of time to work up the courage to take a scissor to your plants –  but it will be worth it for those bigger yields.

What are the Pros and Cons of Fimming?

Fimming is pretty similar to topping but this technique will produce even more colas so is a good choice if you just have a couple of plants growing in order to achieve maximum productivity. It is also pretty easy and hard to get wrong so, while a technique favored by more advanced growers, you can still try it out as a beginner. Simply wait until you have at least 3 nodes on your plant and then pinch the leaves of the most recent node with your finger and thumb.
After a few weeks of the fimming taking place, you will be blessed with at least 4 new colas and it will help your plant to grow bushier. However, fimming it isn’t as effective as topping at reducing the height of your plants and, as it isn’t as ‘stressful’ to plants as topping, it might not always achieve the desired effect.

Deciding between high-stress training techniques for your cannabis plants isn’t easy. Generally speaking, topping is the best technique if you are wanting to manipulate the shape of your plants so that they can absorb more light, and fimming is better for producing more colas and a quicker recovery time for your plants.
The good news is that not a lot can go wrong with either topping or fimming so why not experiment and give them both a try to see what works best for you? Both are great for increasing yields so we recommend that you definitely try a high-stress training technique as part of your growing routine.
