Emerald Harvest Root Wizard 1L — PGPR Root Booster

Emerald Harvest Root Wizard 1L — Plant Growth-Promoting Rhizobacteria

The 1-litre size of Emerald Harvest's flagship root-zone booster — packed with multiple strains of plant growth-promoting rhizobacteria (PGPRs) that colonise the root zone, dramatically increase root mass, and enable plants to absorb significantly more of whatever nutrients you're feeding. Designed primarily for hydroponic systems where active biological root-zone support makes the biggest difference.

Why growers choose Root Wizard 1L:

• 1-litre practical size — enough for multiple grows without committing to commercial bulk
• Multiple PGPR strains — diverse bacterial community, more resilient than single-species products
• Dramatically increases root mass — more root surface area means more nutrient uptake capacity
• Better absorption efficiency — more yield from the nutrients you're already paying for
• Designed for hydroponic systems — PGPRs particularly benefit inert-media setups where soil microbiome is absent
• Helps plants recover from root damage — useful after overwatering, root rot, or transplant stress
• Premium Emerald Harvest formulation — respected US brand with technical backing

Who it's not for:

Incompatible with chlorinated tap water and H₂O₂ — both kill the microbes instantly. Use RO, dechlorinated, or stand-overnight tap water. Not compatible with Athena Cleanse or hypochlorous acid cleansers. If you're already running Advanced Nutrients Voodoo Juice or Piranha, you may get overlapping benefits — pick one, don't stack three microbial products.
