Cronk PuurOrganics Kit: Complete Guide to OMRI Organic NutritionUpdated 10 days ago
PuurOrganics Kit: Professional Organic Nutrition with Complete NPK Control
The PuurOrganics Kit delivers OMRI-certified organic nutrition through a modular 5-part system that provides complete NPK control while maintaining full organic compliance. Adjust nitrogen, phosphorus, and potassium independently at each growth stage—precision previously impossible with organic fertilizers.
Kit Contents
| Product | NPK | Source | Function |
|---|---|---|---|
| PuurNitro | 8-0-0 | Upcycled soy protein | Nitrogen for vegetative growth |
| PuurPhos | 0-12-0 | Upcycled pumpkin seeds | Phosphorus for flowering/roots |
| PuurK | 0-0-15 | Upcycled durian shells | Potassium for quality/stress |
| PuurCalMag | — | Mined limestone/brine | Calcium and magnesium |
| PuurBalance | 2-0-0 | Plant-based amino acids | 21 amino acids + micronutrients |
What Makes PuurOrganics Different
Independent NPK Control
Traditional organic fertilizers are pre-mixed with fixed ratios:
- Seedlings get the same formula as flowering plants
- No way to increase phosphorus without adding unwanted nitrogen
- Compromises at every growth stage
PuurOrganics separates N, P, and K into individual bottles, allowing you to:
- Maximize nitrogen during vegetative growth
- Elevate phosphorus during flowering transition
- Boost potassium during late bloom for quality
- Adjust ratios to match plant-specific needs
Fully Water-Soluble (Hydro Compatible)
Most organic fertilizers contain insoluble particles that:
- Clog drip lines and emitters
- Settle in reservoirs
- Require constant agitation
- Make hydroponics impractical
PuurOrganics products dissolve completely with zero sediment—the first organic line truly compatible with hydroponic systems.
Fast-Acting Organic Nutrition
Traditional organic nutrients require weeks of microbial breakdown before plants can access them. PuurOrganics uses enzymatic processing to pre-convert nutrients to plant-available forms—achieving synthetic-like response times while remaining 100% organic.

Growing System Compatibility
Soil (Excellent)
- Maximum benefit in soil systems
- Amino acids feed soil microbes
- Works in potting mix, living soil, raised beds
Coco Coir (Excellent)
- Fully compatible with coco
- PuurCalMag essential (coco binds Ca/Mg)
- No sediment issues
Hydroponics (Revolutionary)
- First truly hydro-compatible organic line
- Zero sediment, no clogging
- Works in DWC, RDWC, NFT, drip systems
- Maintain proper oxygenation
Living Soil (Excellent)
- Complements soil food web
- Amino acids support microbial populations
- Can be combined with compost teas
Sustainability: Upcycled Ingredients
PuurNitro: Soy Protein
Transforms food industry byproducts into premium nitrogen. Enzymatic processing converts protein to plant-available forms.
PuurPhos: Pumpkin Seeds
Converts food processing waste into concentrated phosphorus. Phytase enzymes release phosphorus from phytic acid.
PuurK: Durian Shells
Transforms Southeast Asian waste disposal problem into potassium-rich fertilizer. Durian shells are among the highest-potassium plant materials.
Compatible Additives
- Armadillo Armour – Silicon (compatible with organic grows)
- Sticky Bandit – Carbohydrates for terpenes and microbes
- Monkey Juice – Beneficial bacteria (excellent synergy)
- Bud Booster – Extra PK during flowering
NOT Compatible
- Cronk Classic Line (Micro, Grow, Bloom)
- Cronk Bonnie & Clyde
- Standard Cronk CalMag (use PuurCalMag instead)
- Other synthetic base nutrients
Frequently Asked Questions
Can PuurOrganics be used in hydroponics?
Yes—this is one of PuurOrganics' major advantages. All five products are fully water-soluble with zero sediment, making them compatible with drip systems, NFT, and DWC.
Why can't I mix PuurOrganics with Classic Line or Bonnie & Clyde?
PuurOrganics uses organic-specific chelation designed to work as a complete system. Mixing with synthetic bases can cause compatibility issues and void organic certification.
How is PuurOrganics different from other organic fertilizers?
Three key differences: (1) Fully water-soluble—works in hydroponics; (2) Fast-acting—enzymatically processed for quick uptake; (3) Modular NPK control—separate N, P, and K for precise feeding.
Are the upcycled ingredients really effective?
Yes. The plant sources were chosen for excellent nutrient profiles, and enzymatic processing converts them to plant-available forms with the same effectiveness as synthetic equivalents.
