This is a good DIY fertilizer you can use during the transition from the vegetative to the flowering phase when growing cannabis. If you have used the DIY Grow Formula, and are in the last week of the vegetative phase, it's time to switch to the "Early Flowering Nutes", and continue to use this for about two weeks before entering the mid bloom phase.
There is an overlapping activity of Phosporous and Potassium during flowering. In natural farming, we apply calphos before the flower initiation to support the eventual fruit. In simplistic terms, we use Phosphorous to address the root system, which will enable the plant to access better water and nutrients from the soil to support the critical changeover as manifested by flower initiation. We use Calcium to strengthen the plant in preparation for heavy flowers/fruits. Thus, natural farming emphasizes Phosphorus and Calcium during the changeover period from growing to flowering/fruiting, and this provides for that need.
Best of all, this can all be found in your own kitchen and doesn't need to cost you anything(!)
This is what you will need:
- Egg shells
- Vinegar
The recipe:
1. Collect a bunch of eggshells and wash to remove inside filaments. Remember, you can also use bones and other good sources of calcium like seashells, clams and oysters, etc. Likewise, if you only want calcium, even limestone can be used, or simple lime.
2. Pan fry the eggshells. Fry until some are brown/black, some white. The burnt shells are your Calcium source while the white are the Phosphorus source (This Will smell when doing inside your home).
3. After roasting the eggshells, grind them up. You can do it manually, with a mortar and pestle, throw them in a blender or electric coffee grinder, etc.
4. Add them to a jar and add 5 parts vinegar by volume. For example, if you have 1 cup ground shells, add 5 cups vinegar.
- The acid in the vinegar helps digest them. You will notice bubbling as this process converts the ingredients to liquid calcium phosphate.
5. Wait until tiny bubbles disappear
6. Seal the jar and ferment for 20 days.
7. Filter into another jar
Congratulations. Youve made your own Calcium Phosphate!
How to Use:
Mix 1tbsp per gallon of water.
