BioBizz Microbes - Beneficial Bacteria & Trichoderma for Healthier Roots
Best for: Growers wanting a stronger root system and more resilient plants by feeding the soil biology, not just the plant.
Our thoughts
A healthy root zone does a lot of the hard work for you, and that's what this product is aimed at. It's a small dose product that works quietly in the background rather than something you'll see instant dramatic results from, but the science behind Trichoderma and beneficial bacteria for root health is well established.
BioBizz Microbes is a blend of beneficial bacteria, enzymes and Trichoderma harzianum fungi, designed to be added to your growing medium to build up a healthier microbial environment around the roots. The formula includes several Bacillus species (including B. velezensis, B. megaterium, B. pumilus and B. licheniformis) alongside Trichoderma harzianum, all of which work with plant roots rather than against them - Trichoderma in particular is known for competing against harmful pathogens and fungal disease while encouraging more vigorous root development.
The enzymes in the mix help break down organic matter in the growing medium into forms plants can actually use, effectively "unlocking" nutrients that would otherwise take longer to become available. BioBizz recommends using it at a rate of roughly 0.2g to 0.4g per litre of water, applied around once a week.
How it compares
Microbial and mycorrhizal root inoculants have become a fairly standard add-on for growers wanting to go beyond basic feeding.
- Great White is a well-known mycorrhizal inoculant with a broader blend of fungal species, generally used as a one-off root-zone treatment rather than a weekly addition.
- Mykos focuses specifically on mycorrhizal fungi rather than the bacterial and Trichoderma blend BioBizz Microbes offers.
- Compared with skipping biological additives altogether, products like this aim to build a more resilient root environment rather than just feeding the plant directly.
If you're already running a BioBizz organic programme, this slots in as a natural extension rather than a separate system to learn.
Usage guidance
Simple to dose alongside your existing feed schedule.
Dosage
Use at 0.2g to 0.4g per litre of water, roughly once a week throughout the grow.
Mixing
Dissolve fully in water before applying to avoid uneven distribution in the medium.
Timing
Introduce it early, ideally from the seedling or cutting stage, so the beneficial organisms are established before the plant needs them most.
Compatibility
Works alongside BioBizz's standard feed range (Bio-Grow, Bio-Bloom, Root-Juice) as part of a full organic programme.

Who this is for
- Organic growers wanting to build up soil biology, not just feed the plant

- Growers focused on maximising root health for stronger overall plants
Best suited to soil and coco growers running a full organic feeding programme.
Our take
Not a flashy product, but a genuinely useful one if root health matters to you - and it should, since roots are doing all the work the rest of the plant depends on.
Worth picking up if you're already invested in the BioBizz range and want to build on it properly.
