Grandpa Dave’s Two-Part Cannabis Growth and Bloom System
Crafted for Cannabis Growers, Powered by Nature
Grandpa Dave’s Two-Part Cannabis Growth and Bloom System isn’t just another plant food that happens to work for cannabis—it’s engineered specifically for cannabis growers, with every ingredient hand-selected to meet the unique demands of this exceptional crop. Our proprietary dry, slow-release formulations are a game-changer in the world of cannabis cultivation, delivering nutrients at precisely the right time and in exactly the right amounts. No one else does what we do—dry fish nutrients and dry fish poo in a powerful, long-lasting format designed to unleash the full potential of your plants.
What truly sets us apart is our exclusive processing system. Unlike other methods that heat-dry, boil, or freeze-dry their products, we use a proprietary technique to create dry fish poo while maintaining all the beneficial bacteria and microbes. This makes Grandpa Dave’s system likely the only one in the world capable of delivering such nutrient-rich, biologically active products in a dry form.
Why Grandpa Dave’s is Different
Unrivaled Formulation
Our two-part system—Cannabis A for vegetative growth and Cannabis B for flowering—combines cutting-edge natural science with traditional cultivation wisdom.
Cannabis A is rich in nitrogen from whole fish and fish poo slurry, building strong roots, stems, and foliage.
Cannabis B focuses on phosphorus and potassium from bat guano and bone meal, driving bud density, resin production, and terpene richness.
Dry, Slow-Release Technology
Unlike liquid fertilizers that deliver nutrients in a rush and risk overwhelming your plants, Grandpa Dave’s dry formulations provide consistent, long-lasting nutrition. Our proprietary system ensures that your cannabis plants receive the nutrients they need, exactly when they need them—promoting steady, robust growth without nutrient spikes or burns.
Dry Fish and Fish Poo: A proprietary process extracts, dries, and blends fish-based nutrients for unmatched performance. This is a one-of-a-kind system in the market.
Sustained Feeding: Slow nutrient release ensures balance and eliminates overfeeding risks.
Eco-Friendly Innovation: By minimizing nutrient runoff, our products protect both your plants and the planet.
Cannabis A: The Vegetative Powerhouse
Designed for Early-Stage Growth Cannabis A is tailored to provide the high-nitrogen nutrition cannabis plants demand during the vegetative stage, laying the foundation for healthy, resilient plants.
Key Ingredients & Benefits
Whole Fish: Packed with nitrogen, essential for chlorophyll production and leafy, vigorous growth.
Fish Poo Slurry: Boosts soil health with a perfect balance of macronutrients (NPK).
Bone Meal: Strengthens root systems and prepares plants for heavy flowering.
Kelp Extract: Enhances root development and stress tolerance.
Soil Sweeteners (Molasses and Yeast): Supercharge microbial activity, improving nutrient breakdown and availability.
Calcium and Magnesium Sources: Epsom salt and powdered eggshells fortify stems and improve photosynthesis efficiency.
Results You’ll See with Cannabis A
Dense, lush foliage that supports future bud growth.
Strong, well-developed root systems ready for the flowering phase.
Enhanced resilience to stress, pests, and environmental changes.
Cannabis B: The Bloom Enhancer
Fuel for Flowering Excellence Cannabis B transitions your plants seamlessly into the flowering phase, focusing on phosphorus and potassium to drive bud formation, resin production, and terpene expression.
Key Ingredients & Benefits
Bat Guano (0-20-0): Delivers concentrated phosphorus for dense bud development and enhanced resin production.
Bone Meal: Provides sustained phosphorus and potassium to fuel flower formation.
Fish Poo Slurry: Maintains balanced macronutrients for ongoing health during flowering.
Kelp Extract: Promotes terpene and resin production for superior flavors and potency.
Soil Sweeteners: Feed beneficial microbes, ensuring nutrient-rich soil throughout the bloom stage.
Calcium and Magnesium Sources: Critical for bud density and cannabinoid synthesis.
Results You’ll See with Cannabis B
Large, resin-rich buds packed with cannabinoids and terpenes.
Enhanced aroma and flavor profiles, perfect for premium-grade cannabis.
Stronger, healthier plants capable of delivering maximum yields.
Beyond NPK: The Holistic Advantage of Fish-Based Nutrients
Many fertilizers focus solely on NPK (Nitrogen, Phosphorus, Potassium) values, but cannabis cultivation requires more than just macronutrients. Grandpa Dave’s system goes beyond NPK to include essential enzymes, trace minerals, and microbial boosters that optimize every stage of your plant’s growth.
Why Fish-Based Nutrients Are Superior
Enzymes for Soil Health: Fish-based products release natural enzymes that break down organic material, enriching the soil and making nutrients more bioavailable.
Trace Minerals for Resilience: Our formulations provide calcium, magnesium, iron, and zinc to support stronger plants, healthier foliage, and richer terpene profiles.
Microbial Boosters: Natural plant sweeteners fuel beneficial bacteria, creating a thriving soil ecosystem that improves nutrient uptake and root development.
The Result?
Higher THC and CBD Levels: Enhanced nutrient delivery supports cannabinoid production.
Improved Terpene Profiles: Magnesium and kelp extract boost terpene synthesis, resulting in richer flavors and aromas.
Balanced Growth: Slow-release nutrients prevent spikes and deficiencies, ensuring consistent, healthy growth throughout the lifecycle.
What Sets Grandpa Dave’s Apart?
A System Designed Exclusively for Cannabis
While other fertilizers are repurposed for cannabis, Grandpa Dave’s was built from the ground up for cannabis growers. Every ingredient was chosen with intention, and every formula was crafted to meet the specific nutritional needs of cannabis plants.
Tailored Nutrition: Cannabis A for vegetative growth and Cannabis B for flowering ensures plants get exactly what they need, when they need it.
Boosted Terpenes and Cannabinoids: Our formulas enhance the production of essential oils, THC, and CBD for more potent, aromatic results.
Unmatched Sustainability
Grandpa Dave’s products are made with sustainably sourced ingredients, including fish poo, whole fish, and natural plant-based sweeteners. Our slow-release technology minimizes runoff, making our products not only better for your plants but also better for the environment.
Backed by Science
