Full Strength Grow Kit by Homegrown Cannabis Co.

From the very first transplant to the final flush, everything you need to feed, fortify, and finish your cannabis plants is now available in one expertly matched bundle.

The Full Strength Grow Kit by Homegrown Cannabis Co. combines three professional-grade products into a complete, stage-by-stage nutrition system: a 100% organic mycorrhizal root inoculant, a controlled-release NPK base fertilizer, and a premium liquid Cal-Mag supplement, all three working together seamlessly from root establishment through peak flower production.

We've eliminated the complexity of building a compatible feeding program from scratch so you can focus entirely on the grow. No guesswork. No compatibility issues. Just stronger roots, sustained growth, and bigger, more potent buds.

Our Full Strength Grow Kit is the essential nutrient bundle for cultivators who want a solid biological foundation, reliable macro-nutrition, and targeted secondary supplementation: all from a single, trusted source.

Kit Contents: The Complete Path from Root to Harvest

This precision 3-product kit is a curated nutritional ecosystem, featuring perfectly paired components that address the three most critical pillars of cannabis plant health: root zone biology, sustained NPK feeding, and secondary nutrient balance.

• Underground Mix – Mycorrhizae Powder (14oz / 396g): A 100% organic biological inoculant that introduces beneficial fungi to the root zone at transplanting, forming a living symbiotic network that dramatically improves nutrient and water uptake, reduces transplant shock, and establishes a biological foundation that benefits the plant for its entire lifecycle.
• Evergreen Charge – NPK Controlled Release Fertilizer (16oz / 453g): A controlled-release fertilizer whose coated prills deliver a steady, consistent supply of balanced NPK nutrients for up to 4–8 weeks per application, responding to soil temperature and moisture for natural, plant-synced feeding with minimal maintenance.
• Fortify Pro – Cal-Mag Supplement (8oz / 250ml): A premium liquid calcium and magnesium supplement that instantly corrects and prevents common secondary nutrient deficiencies, strengthens cell walls, and actively supports terpene and cannabinoid development for bigger, more potent, and more flavorful buds.

Why Choose the Full Strength Grow Kit by Homegrown Cannabis Co.?

This kit is engineered to give your plants the strongest possible nutritional foundation at every stage of growth. It delivers:

• Root-to-harvest coverage: Underground Mix builds a thriving biological root zone at transplanting, Evergreen Charge sustains steady macro-nutrition through veg and flower, and Fortify Pro fills secondary nutrient gaps throughout the entire cycle. All three working in sync.
• 3 perfectly compatible products: Every item is formulated to work alongside the others, removing the guesswork and compatibility risks that come from mixing products across different brands.
• Organic biological foundation: Underground Mix is a 100% organic mycorrhizal inoculant. Once established at transplant, the mycorrhizal colony it creates lives symbiotically with your plant's roots for the entire lifecycle, no repeat applications needed.
• Set-and-forget base nutrition: Evergreen Charge's controlled-release technology feeds plants steadily for weeks, dramatically reducing overfeeding risks and making the feeding schedule more manageable for growers at any experience level.
• Fast-acting deficiency correction: Fortify Pro's liquid formula is immediately available for plant absorption, quickly preventing and correcting the calcium and magnesium shortages that most commonly limit bud size and potency during flowering.
• Universal medium compatibility: Soil, coco, soilless mixes, hydroponics, and outdoor gardens. Every product in this kit is designed to perform across all growing environments.
• Beginner-to-pro ready: Clear dosing guidelines and straightforward application methods make this kit approachable at any experience level, while delivering the kind of results experienced growers expect.
