Humboldt County's Own Deep Fusion Micro

Most growers using standard 3-part systems face micronutrient deficiencies when pH drifts, forcing them to purchase separate cal-mag supplements and struggle with iron lockout issues that leave plants yellowing and stunted. Humboldt County's Own Deep Fusion Micro eliminates these problems by delivering a complete micronutrient package (5-0-1) with large amounts of calcium and nitrogen, plus two types of chelated iron—EDDHA and DTPA—that remain bioavailable under a wide range of pH conditions. This advanced dual-chelate system contains no EDTA, ensuring plants have ample iron even when pH fluctuates outside the ideal range.

Deep Fusion Micro stands apart from competing micronutrient formulas through its integration of molasses alongside all standard chelated micronutrients and trace elements necessary for healthy, vigorous growth. The molasses contains numerous additional trace elements that provide an extra micronutrient boost beyond what chemical-only formulas can deliver. This organic component is a key reason why Deep Fusion enhances the "esthetics"—resin production, fragrance, and taste—that growers value most. There's just something about organics that elevates final product quality in ways pure chemical nutrients cannot replicate.

As the foundation of the Deep Fusion 5-part system in 3 bottles, Deep Fusion Micro works synergistically with Deep Fusion Grow and Deep Fusion Bloom to provide complete nutrition throughout the plant's life cycle. While Grow and Bloom ratios adjust based on growth stage, Deep Fusion Micro remains consistent, supplying the steady calcium, nitrogen, and chelated micronutrients that plants need from seedling through harvest. This eliminates the guesswork and expense of purchasing separate cal-mag products, iron supplements, and micronutrient additives.

Part of the Complete Deep Fusion System

Deep Fusion Micro (5-0-1) + Molasses + Calcium: Provides growing plants with large amounts of calcium and nitrogen, plus chelated micronutrients and trace elements essential for healthy development. Features two types of chelated iron (EDDHA and DTPA) to maintain iron availability under a wide range of pH conditions. Contains no EDTA chelates. Use consistently throughout all growth stages as the foundation of your feeding program.

Deep Fusion Grow (2-3-6) + Molasses + Kelp: Promotes vigorous stem and leaf growth during vegetative stages while increasing the effectiveness of Deep Fusion Bloom during the flowering cycle. The integrated kelp provides natural plant growth regulators and trace minerals that improve plant strength. Use higher ratios during veg, then reduce when transitioning to bloom.

Deep Fusion Bloom (0-6-4) + Molasses + Magnesium: Supplies massive amounts of phosphorus for robust flower development along with additional magnesium that complexes with molasses for superior bioavailability. Increase ratio during flowering while maintaining consistent Deep Fusion Micro for micronutrient support.

Directions for Use

Deep Fusion Micro is designed as the foundation of the complete 3-part nutrient system for soil and hydroponic applications. Maintain consistent Micro levels throughout all growth stages while adjusting Grow and Bloom ratios based on plant needs.

General Guidelines:

  • Always add nutrients to water, never add water to nutrients
  • Add Deep Fusion Micro FIRST, then Grow, then Bloom
  • Shake bottle well before use to ensure proper mixing of organic and chemical components
  • Monitor pH and adjust to optimal range for your growing medium
  • Keep Micro levels consistent throughout vegetative and flowering stages
  • The dual-iron chelate system provides insurance against pH fluctuations
  • Do not reduce Micro when transitioning to bloom—plants need steady calcium and micronutrients

Pro Tips:

  • No need to purchase separate cal-mag supplements—Micro provides large amounts of calcium
  • No need to purchase separate iron supplements—dual-chelate system prevents deficiencies
  • The molasses trace element boost enhances resin, fragrance, and taste
  • EDDHA and DTPA chelation provides superior stability compared to EDTA products
  • Works in both soil and hydro systems without micronutrient lockout issues
  • Compatible with other Humboldt County's Own supplements like the Starter Pack for advanced feeding programs

Frequently Asked Questions

Why does Deep Fusion Micro use EDDHA and DTPA instead of EDTA?+

EDDHA and DTPA provide superior iron availability across a much wider pH range than EDTA. EDDHA remains effective in alkaline conditions up to pH 9, while DTPA works well in acidic to neutral pH. Most products use only EDTA because it's cheaper, but EDTA becomes ineffective when pH drifts above 6.5 or below 6.0—the exact conditions that cause iron deficiency yellowing in many grows. Deep Fusion Micro's dual-chelate system prevents these deficiencies regardless of minor pH fluctuations.

Do I still need to buy a separate cal-mag supplement?+

No, Deep Fusion Micro provides large amounts of calcium as a core component of the formula, eliminating the need for separate cal-mag products. The 5-0-1 analysis includes substantial calcium and nitrogen to support strong cell structure and growth throughout the plant's life cycle. By maintaining consistent Deep Fusion Micro levels while adjusting Grow and Bloom ratios, you provide steady calcium and micronutrient nutrition without purchasing additional supplements. This integration saves money and simplifies your feeding routine.

How does molasses in Deep Fusion Micro improve plant quality?+

Molasses contains numerous trace elements beyond what's listed on standard nutrient labels, providing an extra micronutrient boost that chemical-only formulas cannot deliver. This organic component is a key reason why Deep Fusion enhances the "esthetics"—resin production, fragrance, and taste—that growers value most in their final product. The same principle applies to products like Killer Tea that boost quality through organic components. There's just something about organics that elevates final product quality in ways pure chemical nutrients cannot replicate.

Should I reduce Deep Fusion Micro when transitioning to bloom?+

No, maintain consistent Deep Fusion Micro levels throughout all growth stages. While you adjust the ratios of Deep Fusion Grow and Deep Fusion Bloom based on whether plants are in veg or flower, Micro should remain steady because plants need continuous calcium, nitrogen, and chelated micronutrients from seedling through harvest. Reducing Micro during bloom can lead to calcium deficiencies and micronutrient lockout that compromise flower development. Think of Micro as the foundation—Grow and Bloom adjust, but Micro stays consistent.

What micronutrients are included in Deep Fusion Micro?+

Deep Fusion Micro contains all the standard chelated micronutrients necessary for healthy, vigorous growth including iron (EDDHA and DTPA chelation), manganese, zinc, copper, boron, and molybdenum, plus trace elements. The integrated molasses provides additional trace elements beyond what's in chemical nutrients alone. This complete micronutrient package ensures plants have access to every element needed for optimal metabolism, enzyme function, and healthy development throughout the growth cycle.

Can Deep Fusion Micro be used in both soil and hydroponic systems?+

Yes, Deep Fusion Micro works in both soil and hydroponic applications. The dual-chelate iron system and chelated micronutrients remain stable and bioavailable in both growing methods. In soil, the molasses component provides additional benefits by supplying trace elements and supporting beneficial soil biology. In hydro, the complete mineral package maintains optimal micronutrient nutrition in solution. The superior EDDHA and DTPA chelation prevents micronutrient lockout regardless of growing medium—just monitor and adjust pH appropriately.

How does the dual-chelate iron system prevent deficiencies?+

Iron deficiency typically occurs when pH drifts outside the narrow range where EDTA-chelated iron remains bioavailable (pH 6.0-6.5). By using both EDDHA (effective in alkaline conditions) and DTPA (effective in acidic to neutral pH), Deep Fusion Micro ensures plants have access to iron across a much wider pH range. If pH rises, EDDHA keeps iron available. If pH drops, DTPA maintains availability. This dual-chelate insurance prevents the yellowing new growth and stunted development that plague growers using inferior single-chelate products.

Why should Deep Fusion Micro be added first when mixing nutrients?+

Adding Deep Fusion Micro first prevents nutrient lockout and ensures proper mixing. Calcium in Micro can react with phosphorus and sulfates in Grow and Bloom if they're added in the wrong order or mixed too concentrated, potentially forming insoluble precipitates. By adding Micro to water first and mixing thoroughly, then adding Grow, then Bloom, you ensure all nutrients remain in solution and bioavailable. This proper sequence prevents nutrient interactions that could reduce effectiveness or clog hydroponic systems.
