Your Complete Grow System – Usage Guide

1. Underground Mix – Mycorrhizae Powder

• When: One-time use, at transplanting only
• How: Mix directly into the backfill soil surrounding the roots — use 1 tsp (5g) for small pots, 1 tbsp (15g) per gallon of media for larger containers
• Why: Introduces beneficial fungi to the root zone, forming a symbiotic network that dramatically improves nutrient and water uptake and reduces transplant shock

2. Evergreen Charge – NPK Controlled Release Fertilizer

• When: Throughout vegetative and flowering stages, per feeding schedule
• How: Mix 1 tsp (5g) per gallon of media as a soil amendment, top-dress around established plants, or dissolve ½ tsp (2.5g) per gallon of water for a weekly drench
• Why: Coated prills release balanced NPK nutrients gradually in response to soil temperature and moisture, providing consistent, plant-synced feeding for up to 4–8 weeks per application

3. Fortify Pro – Cal-Mag Supplement

• When: As needed throughout the grow cycle, especially during rapid vegetative growth and flowering
• How: Add 3–5 ml per gallon to your nutrient solution as a root feed, or mix 5 ml per gallon of water and apply as a foliar spray during low-light hours
• Why: Prevents and corrects calcium and magnesium deficiencies, strengthens cell walls, and supports the production of terpenes and cannabinoids for bigger, more potent buds

Recommended Feeding Timeline

Frequently Asked Questions

Can I use all three products together?

Yes, that's exactly what this kit is designed for. Each product targets a different aspect of plant nutrition, so they complement rather than compete with one another. Underground Mix builds the biological foundation at transplant, Evergreen Charge provides ongoing macro-nutrition, and Fortify Pro fills in secondary nutrient gaps as needed.

Is this kit suitable for beginners?

Absolutely. The controlled-release technology in Evergreen Charge makes overfeeding much harder, and the clear dosing guidelines for all three products eliminate the guesswork that trips up new growers. Underground Mix requires just a single application, making it especially easy to use.

Do these products work in hydroponics?

Fortify Pro is fully compatible with hydroponic systems. Underground Mix and Evergreen Charge are best suited to soil, coco, and other solid grow media where controlled release and mycorrhizal colonization are most effective.

How long will the kit last?

The Underground Mix 14oz bag is sufficient for multiple transplants across many plants. The Evergreen Charge 16oz bag provides several months of base feeding at standard rates. Fortify Pro's 8oz liquid bottle covers the full flowering cycle for several plants when used at recommended doses.

Can I use this kit alongside other nutrients?

Yes. Evergreen Charge works as an excellent foundational base that can be supplemented with targeted liquid additives. Fortify Pro is designed to be compatible with most base nutrient schedules, just add it to your existing mixed solution.

With the Full Strength Grow Kit, you get everything needed to feed your cannabis plants with confidence at every stage of the growth cycle. From the first transplant to the final flush, this complete nutrition system sets your plants up for their best harvest yet. Ready to grow like a pro? Start with the right foundation.
