Worm Castings During Cannabis Flowering  

Are worm castings required during cannabis flowering? It’s been said that the cannabis plant is like a “weed” because it grows so easily.

Worm Castings During Cannabis Flowering

But while it may be easy to grow, there are still some things you need to know in order to produce the best yields and highest quality flowers. One of those things is when to add worm castings to your flowering plants. 

Benefits of Worm Castings  

Some of the major benefits of using worm castings are discussed below. 

Worm castings are an excellent source of nutrients for cannabis plants. They are high in nitrogen, phosphorus, and potassium, as well as other essential minerals. Worm castings also help to improve drainage and aeration in the soil, and they can help to suppress harmful fungi and bacteria. 

Additionally, worm castings are known to increase the trichome production of cannabis plants. Trichomes are tiny, crystal-like structures covering the plant’s buds and leaves. They are what give cannabis its unique smell and flavor, as well as its psychoactive properties. 

The Disadvantages of Worm Castings  

While worm castings offer many benefits, they also have some disadvantages. One of the biggest disadvantages is that they can be very expensive. Another disadvantage is that they can attract animals and insects if not used properly. Finally, worm castings can also contain harmful bacteria and fungi if they are not properly composted. 

Thus, it is essential that you only purchase worm castings from a reputable source and that you follow the instructions on how to use them properly. 

Applying Worm Castings to Plants and Soil 

Worm castings can be applied to both plants and soil. When applying to plants, it is best to mix the worm castings with water and then apply them to the leaves and stems. This will ensure that the plant gets the nutrients it needs. If you are applying worm castings to the soil, you can simply add them to the top of the soil and then water them in. 

Worm castings can be applied at any time during the growth cycle. However, they are most beneficial when applied during the flowering stage. This is because plants need extra nutrients to produce large, high-quality flowers. 

Growing in Pure Worm Castings: Is That a Thing? 

You may have heard of growers using pure worm castings as a growing medium. While this is technically possible, it is not recommended. This is because pure worm castings can be very difficult to manage, and they can also attract pests and animals. 

If you decide to use pure worm castings, be sure to purchase them from a reputable source. Also, be sure to mix them with other materials, such as coco coir or perlite, to improve drainage and aeration. 

How Often Should You Use Worm Castings? 

There is no set answer to this question. It depends on the needs of your plants and the quality of your worm castings. However, as a general rule of thumb, you should use worm castings every two to four weeks during the vegetative stage and every week during the flowering stage. 

You should not overuse worm castings, as this can lead to problems such as nutrient burn. If you see your plants starting to yellow or wilt, reduce the amount of worm castings you are using.
