Underground Mix Mycorrhizae Powder from Homegrown Cannabis Co. introduces a powerful colony of beneficial fungi directly into your root zone, forming a living symbiotic network that dramatically improves nutrient uptake, reduces transplant shock, and lays the biological foundation for explosive, vigorous growth above and below the soil line.
Applied at the critical moment of transplanting, Underground Mix works in harmony with Homegrown Cannabis Co's full nutrient program to give your plants a long-term biological advantage from day one.
Underground Mix Main Benefits
- Root System Enhancement: Encourages massive, healthy root development for superior nutrient and water absorption
- Transplant Stress Reduction: Minimizes shock and accelerates plant establishment in new containers
- Extended Nutrient Access: Mycorrhizal filaments reach far beyond the root zone to access additional resources
- Improved Plant Resilience: Strengthens plants against environmental stressors such as drought and heat
- 100% Organic Inoculant: A natural, sustainable biological amendment with no synthetic inputs
- All-Medium Compatible: Effective in soil, coco, soilless mixes, and outdoor garden beds
Differentiating Features
Underground Mix outperforms simple root boosters by delivering:
- Living Root Network: Creates a mycelium web that actively feeds the plant throughout its lifecycle
- Transplant-Optimized Formula: Designed specifically for the critical window of repotting and establishing
- Lasting Soil Health: Once colonized, the mycorrhizal network benefits your plant from seedling to harvest

FAQs
When is the best time to apply Underground Mix?
The most effective application window is at transplanting or when planting seeds and clones. This allows the fungi to colonize roots as they develop.
Can I add it to a pot that's already planted?
Yes, though it is less effective. Mix it into the top layer of soil and water thoroughly — however, direct root contact at transplant always delivers the best results.
Is Underground Mix organic?
Yes. Mycorrhizae are naturally occurring beneficial fungi, and this product is a certified organic soil amendment.
How long will it remain active in the soil?
Once established, the mycorrhizal colony lives symbiotically alongside your plant's roots for its entire lifecycle.
