Nettle manure is a proven, natural fertilizer that can work wonders for growing cannabis. It's rich in nitrogen, potassium, and other important nutrients that promote your plants' growth. In this article, you'll learn how to make your own nettle manure and how to dose and use it correctly to ensure healthy and vigorous cannabis plants.
Why nettle manure?
Nettle manure offers numerous advantages for cannabis cultivation:
- Nutrient-rich : It contains high amounts of nitrogen, which promotes vegetative growth.
- Soil improvement : It supports soil health and promotes microbial activity.
- Pest repellent : It helps keep pests like aphids away.
Production of nettle manure
What you need:
- Fresh nettles (approx. 1 kg)
- Water (approx. 10 liters)
- bucket or barrel
- Lid or grille (for covering)
- Stick or stirring rod
Here's how:
- Collecting : Collect about 1 kg of fresh nettles. Wear gloves to avoid skin irritation.
- Chop : Cut the nettles into small pieces.
- Soaking : Place the crushed nettles in a bucket or barrel and fill it with 10 liters of water.
- Cover : Cover the container with a lid or screen to keep insects out, but allow some air circulation.
- Fermentation : Let the mixture ferment for about 1-2 weeks. Stir daily. The slurry is ready when it no longer foams and has a dark color.
Application and dosage
Dilution:
Nettle manure is very concentrated and must be diluted before use. Use a ratio of 1:10 (one part manure to ten parts water).
Application:
- During the growth phase : Water your cannabis plants every two weeks with diluted nettle manure. This supports vegetative growth and ensures strong plants.
- Flowering phase : During the flowering phase, you should reduce or stop the application completely, as too much nitrogen can impair flower growth.
Additional tips:
- Foliar feeding : You can also use the diluted manure as a foliar fertilizer. Spray it on your plants' leaves to improve nutrient absorption. Be sure to do this only in the early morning or late evening to avoid sunburn.
- Compost : The remaining nettles from the liquid manure can be added to the compost and thus provide additional nutrients.
Conclusion
Nettle manure is an easy-to-make and extremely effective fertilizer for cannabis cultivation. With the right dosage and application, you can significantly improve your plants' growth while protecting the environment. Try it and see for yourself how your cannabis plants thrive!
Remember to always be careful when making and applying nettle manure to avoid skin irritation and to follow the legal regulations in your country. Good luck with your cultivation!
