About this product
Built for roots. Built for results.
RhizoCarbon is a professional-grade liquid fertilizer powered by soluble carbon, humic acids, and fulvic acids — the building blocks of a thriving root system. Most fertilizers feed the plant. RhizoCarbon feeds the foundation.
Developed for professional growers and reformulated for home use, it supercharges root development, improves nutrient uptake, and creates the soil conditions your plants need to actually thrive — not just survive.
Works on all houseplants, potted plants, and indoor growing setups. Best used alongside a booster like Doonbeg or Octane Boost for the complete system.

The science
Why RhizoCarbon works: Nutrx™ technology
Every GardenIQ formula is powered by Nutrx™ — a proprietary blend of carbon complexes, humic and fulvic acids, enzymes, and amino acids developed through decades of professional agronomic research. Most fertilizers sit in the soil. Nutrx™ is designed to maximize how much your plants actually absorb — so you see more results with less product, and dramatically reduced burn risk.
