Plant health products support stronger roots, better nutrient uptake and greater resilience to stress in hydroponic, coco and soil growing. This range covers silica-based fertilisers like MILLS Vitalize, microbial inoculants such as MycoGold and HyMax Phosphorus, and root zone sterilisers like LIQUID SCIENCE Pure Guard — suited to first-time growers and experienced cultivators alike.
Why plant health matters
Healthy roots and an active microbial rhizosphere underpin everything else in a grow — nutrient uptake, stress tolerance and disease resistance all start below the surface. Inert media like coco coir and LECA have little natural biology of their own, so introducing beneficial fungi and bacteria, plus structural nutrients like silica, helps plants establish faster and cope better with heat, transplant shock and nutrient swings.
What's in this collection
MILLS Vitalize — silica-based fertiliser that strengthens stems and cell walls, for use from seedling through to harvest
MycoGold Mycorrhizal Fungi — complete endo and ectomycorrhizal blend with beneficial bacteria, Australian made for coco, LECA, soil and hydro
HyMax Phosphorus — microbial inoculant with six probiotic strains that unlock bound phosphorus for better nutrient cycling
LIQUID SCIENCE Pure Guard — soy-based root zone steriliser and mould inhibitor for a clean, healthy root zone
How to choose
Silica vs. microbial support
MILLS Vitalize is a structural additive that strengthens stems and cell walls, while MycoGold and HyMax Phosphorus introduce living fungi and bacteria that build a working root zone ecosystem — particularly useful in inert media like coco coir and LECA that have no natural biology of their own.
Preventative vs. recovery
Pure Guard is best used preventatively, sterilising the root zone before problems start. If plants are already showing yellowing leaves or deficiency symptoms, a fast-acting recovery product such as CYCO Dr Repair is designed to correct chlorosis quickly, while CYCO B1 Boost and GROWTH TECHNOLOGY Rootzone support root development and reduce transplant shock during cloning and potting on.
If you're just starting out, MycoGold is a simple, low-cost way to build root zone biology from the first transplant. Experienced growers running a full feeding program often layer several of these together — MILLS Vitalize for structure, a microbial inoculant for biology, and an all-in-one treatment like PureCrop1 on hand for pest or mildew issues.
