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.

Will Last Forever
Size: One Size, Color: Black (Bifold), Size: One Size, Color: Black (Bifold)
I’m writing this review after owning the wallet for about two years. I will only buy Carhartt wallets after the first one I had about 8 years ago, and this wallet is a prime example of why. It is the most durable wallet on the market. It is minimalist, but attractive. The best part is that it is made of high quality leather that develops a nice patina over time and looks even better with age in my opinion. It’s the perfect thickness to stay together for years without undue wear, and soft enough to be maneuvered easily, even with pre-arthritic fingers. This wallet is the best value for the money because it will last forever. I’ve owned 2, but only because I lost one.

Toughness & Durability that Carhartt is known for.
Size: One Size, Color: Carhartt Brown (Bifold)
This wallet is working out very nicely. It is comfortable and fits many cards without feeling bulky. I would buy again. Of course, it has the typical toughness/durability that Carhartt is known for and it matches my backpack. :)
