Making a tea for cannabis cultivation using shellfish, worm castings, and wood ash is an excellent organic approach to provide nutrients and improve soil health. Here’s a guide to preparing it:
Ingredients:
1. Shellfish (e.g., crab or shrimp meal) personally I really like crawfish :
Rich in calcium, phosphorus, and chitin, which supports plant growth and soil health.
2. Worm castings:
High in beneficial microbes and nutrients like nitrogen, phosphorus, and potassium.
3. Wood ash:
Provides potassium and raises soil pH, but use sparingly to avoid over-alkalizing.
Tools:
• A 5-gallon bucket
• Air pump and air stone (optional, for aerobic tea)
• Water (preferably non-chlorinated)
• Cheesecloth or fine mesh bag (optional, for straining)
Instructions:
1. Prepare the Base:
Fill the bucket with 4-5 gallons of non-chlorinated water. Let tap water sit for 24 hours to dechlorinate, or use filtered water.
2. Add the Ingredients:
• Shellfish Meal: Add about 1/2 to 1 cup.
• Worm Castings: Add 1-2 cups.
• Wood Ash: Add 1-2 tablespoons (sparingly, to prevent nutrient imbalance).
3. Aerate (Optional):
Use an air pump and stone to keep the tea aerobic, which encourages beneficial microbial activity.
4. Brew:
Let the mixture steep for 24-48 hours, stirring occasionally if not aerating.
5. Strain and Use:
Strain the tea if necessary and dilute it with water in a 1:1 ratio. Apply it directly to the soil or as a foliar spray.
Tips:
• Test Soil pH: Before adding wood ash, ensure your soil can handle an increase in pH.
• Use Immediately: The tea is most effective when used fresh.
• Avoid Overdoing It: Apply the tea once every 2-3 weeks to prevent nutrient buildup.
This tea will provide essential nutrients, improve microbial life, and promote healthy cannabis growth.
