The Classic 3-Part Kit provides complete plant nutrition through three complementary formulas: Micro (5-0-1) establishes the micronutrient foundation, Grow (2-1-6) drives vegetative development, and Bloom (0-5-3) supports flowering. This professional system gives growers precise control over nutrient ratios at every growth stage—something single-bottle fertilizers cannot offer.
Pre-mixed all-in-one fertilizers deliver fixed ratios regardless of growth stage. Seedlings get too much phosphorus. Flowering plants get excess nitrogen. The Classic 3-Part system eliminates these compromises through adjustable mixing ratios that match actual plant requirements throughout the entire lifecycle.
Kit Contents
- Micro 5-0-1 – Calcium, iron, and chelated trace minerals (add first)
- Grow 2-1-6 – Balanced vegetative nutrition with elevated potassium
- Bloom 0-5-3 – Nitrogen-free flowering formula with elevated PK
Key Benefits
- Adjust NPK ratios for each growth stage instead of accepting fixed formulas
- Fully soluble for soil, coco coir, and hydroponic systems
- Professional-grade nutrition used by commercial cultivators
- Same three bottles work from seedling through harvest
Recommended Additions
Add CalMag for coco coir, RO water, or LED grows. Add Bud Booster during flowering for enhanced bloom performance. Upgrade to the Big Bud Kit for the complete package.
