Project: Homemade Fermented Fruit Juice (FFJ) for Cannabis Cultivation
What is FFJ?
FFJ (Fermented Fruit Juice) is a natural, homemade nutrient rich in:
Sugars
Enzymes
Hormones
Vitamins
It's a core part of Korean Natural Farming (KNF) but also perfect for low-cost, organic grows. Helps with plant health, growth, and overall vitality.
Ingredients:
0.5 kg pumpkin skins
0.5 kg watermelon skins
250 g used coffee grounds
0.5 kg cannabis leaves
0.5 kg tomato leaves
200 g broccoli

Tools:
8l plastic bucket (no metal)
Cheesecloth or breathable lid
Scale for measuring
Preparation:
1. Chop the fruits and greens into pieces.
2. Weigh the total biomass and add equal weight of sugar.
3. Mix until everything is coated.
4. Place in jar, cover with cloth.
5. Store in a dark, warm place for 5–7 days (stir daily).
6. Once fermented, strain the liquid = this is your FFJ.
Application:
Vegetative stage: 1–2 ml per liter of water
Flowering stage: 0.5–1 ml per liter (optional)
Apply 1–2 times per week
Notes:
FFJ boosts microbial life
Increases flavor, aroma, and plant resilience
Works in soil, coco, and hydro (small doses)
Next Steps:
Prepare first batch (Pumpkin, Watermelon, Coffee, Cannabis leaf, Tomato leaf, Broccoli, Chicken, Eggshell mix)
Document fermentation process (photos + notes)
Apply to current grow and track results
