Worm castings, also known as vermicompost, are a natural fertilizer that's especially valuable for cannabis cultivation. It's produced by worms digesting organic matter and is packed with nutrients that promote your plants' growth. In this blog post, you'll learn why worm castings are so effective, how to use them, and what benefits they offer specifically for cannabis plants.
Why is worm humus so valuable?
Worm castings contain a wealth of nutrients and microorganisms that improve soil quality and, in turn, the health of your plants. Here are some reasons why worm castings are so popular for cannabis cultivation:
-
Rich in nutrients : Worm humus contains important nutrients such as nitrogen, phosphorus, potassium, magnesium and calcium that your cannabis plants need for growth and flowering.
-
Improved soil structure : Worm humus loosens the soil and improves drainage and air circulation in the root zone. This allows the roots to breathe better and absorb water more easily.
-
Promotes microorganisms : Worm humus is rich in microorganisms that help break down organic matter in the soil and convert it into nutrients available to plants.
-
Strengthening plants against diseases : The microbes contained make the plant more resistant to diseases and pests.
Benefits of worm humus in cannabis cultivation
Cannabis plants have specific needs that worm castings can support perfectly. Here are some of the benefits for your plants:
- Natural growth booster : The nutrients in worm castings promote both vegetative growth and flowering. Your plants will become stronger, which ultimately also influences the harvest.
- Long-term nutrient supply : Worm humus releases its nutrients slowly, which means that your plants are supplied over a longer period of time without over-fertilization.
- Promoting root formation : Soil improvement stimulates root growth, making the plant stronger and more robust.
How to use worm castings in cannabis cultivation?
Worm humus can be used in several ways in your cannabis grow:
-
Mix when planting : Mix worm castings directly into the growing soil when planting your cannabis seeds. This ensures that the young plants receive essential nutrients right from the start.
-
Top Dressing : Place a layer of worm castings on top of the soil around your plants. With each watering, nutrients from the worm castings will be washed into the soil and reach the roots.
-
Making worm casting tea : Worm casting tea is a liquid fertilizer that is quickly absorbed by the roots. To make it, mix about one cup of worm castings with 5 liters of water, let it steep for 24 hours, stirring occasionally. Then, water your plants with the tea or spray it on the leaves.
How much worm castings should you use?
Worm castings are highly nutritious, yet gentle enough not to overfertilize your plants. As a general rule of thumb, mix about 10-20% worm castings into your growing soil or use about a handful of worm castings per pot as a top dressing. With worm casting tea, a single application every two weeks is sufficient.
Where can you get high-quality worm humus?
High-quality worm castings are available in many garden and grow shops, as well as online. When purchasing, make sure the castings are made without chemical additives. Alternatively, you can also create your own worm castings and produce them yourself.
Conclusion
Worm castings are a natural, versatile fertilizer that offers many benefits to your cannabis plants. Regular use can improve the growth, health, and harvest quality of your plants. Whether as a soil additive, top dressing, or worm castings tea, this organic fertilizer is ideal for anyone who values sustainable and successful cannabis cultivation.
