Description
MYCO CHUM 473ML is the concentrated mycorrhizal and biological stimulant tea from Oregon’s Finest Organics that delivers a diverse consortium of beneficial fungi, bacteria, and biological growth promoters directly to the root zone in a highly bioavailable liquid format. We have been recommending Myco Chum to UK growers since 2017 as one of the most comprehensive and effective biological root zone conditioners available in the UK grow market.
Why Liquid Biological Inoculants Deliver Exceptional Root Zone Results
Mycorrhizal fungi and beneficial bacteria in dry powder inoculants must rehydrate and activate before colonising the root zone, and their viability depends heavily on storage conditions and the time elapsed since manufacture. Myco Chum’s liquid format presents these organisms in an already active, suspended state with the nutrients and growth cofactors needed to sustain them through the critical period of root zone establishment. The formulation includes multiple species of mycorrhizal fungi alongside phosphorus-cycling, nitrogen-fixing, and pathogen-suppressive bacteria — a functional community rather than a single-species inoculant. This biological diversity more closely mimics the complex rhizosphere community of productive natural growing environments, providing the full range of root zone services that a diverse microbial ecosystem delivers. The organic matter present in the Myco Chum matrix also serves as a substrate that sustains the introduced organisms as they establish in the root zone.
Application, Compatibility, and the 473ml Format
Myco Chum is applied as a root drench throughout the vegetative and early flowering phases. Shake well before use and apply at the manufacturer’s recommended rate — the concentrated formula is highly economical per application. Compatible with soil and coco growing media and with most organic and synthetic nutrient programmes at standard doses. Avoid combining with bactericidal agents including hydrogen peroxide, systemic fungicides, and high-concentration beneficial organism killers. Myco Chum pairs naturally with Fish Sh!t Organic Soil Conditioner from the same Oregon’s Finest Organics range for a comprehensive biological root zone programme. The 473ml (16 fl oz) format is the standard size in the Oregon’s Finest Organics range, providing extended use at the concentrate application rate.
