Topping Your Medical Marijuana Plants
What is Topping and Why is it Important?
Topping is when you remove the very top of the main stem in order to provide more light to axillary buds which will grow into two main colas instead of one. One of the most important things to note is to not top your plants too early. If you do, you run a high risk of that plant not being able to recover. A general rule of thumb is to wait until each plant has about four to five nodes. Once the plant reaches this height it's ready to be topped.
Simply find the top piece of your main stem and cut it right above the node, making sure to avoid snipping the axillary buds. This will help your plant grow in a more horizontal direction.
You only really need to top a plant if you have height restrictions from your indoor grow. Otherwise, there are many other methods that produce higher yields and pose less of a risk to your medical marijuana crops.
What is Fimming?
Fimming (also spelled FIMing) stands for "f*ck I missed." Similar to topping, Fimming helps the plant grow in a more lateral direction.
If you look at the picture to the right, you will see the lines indicating where to cut in order to top or to FIM. Fimming is just removing part of the growth tip to allow a little more light to those axillary buds.
Topping is when you removed the entire growth tip right above the node and the axillary buds. Both methods are used to keep plants short and bushy.
If you love the idea of short and bushy plants, or your grow space limits your vertical grows consider topping a few of your plants.
If you're new to this concept only top a few plants in your grow to minimize risk. You'll want to experiment and see which plants produced the best yields.
