Xtreme Gardening®

Microbial Power, Maximum Performance

Xtreme Gardening® is a leader in microbial-based plant enhancement, bringing cutting-edge biological solutions to gardeners and growers who want more from their plants without relying on synthetic inputs. Born from Reforestation Technologies International in 2008, Xtreme Gardening® leverages decades of microbial science originally developed for forestry and ecological restoration, now adapted for high-yield horticulture and home growing.

Their flagship product, MYKOS, uses living mycorrhizal fungi to build a symbiotic relationship with roots, expanding nutrient uptake zones and boosting water efficiency. AZOS adds a powerful nitrogen-fixing bacteria that helps plants convert atmospheric nitrogen into a usable form, promoting explosive vegetative growth and improving clone rooting and transplant success. Both are known for delivering visible improvements in plant health, vigour, and yield.

In addition to these biological heavyweights, Xtreme Gardening® offers CalCarb, a foliar calcium supplement that also boosts internal CO₂ levels for photosynthetic efficiency, and Xtreme Tea Brews, a user-friendly microbial compost tea designed to build soil life and plant resilience. All products are developed with clean, sustainable cultivation in mind, and are compatible with soil, coco, and hydroponic systems alike.

At Hydro Oasis, we stock Xtreme Gardening® because it provides professional-grade biological tools for growers who want to maximise plant potential while staying rooted in nature. Whether you are chasing bigger blooms, stronger roots, or a healthier growing environment, Xtreme Gardening® gives your plants the microbial edge they need to thrive.

MYKOS WP

MYKOS® WP is the wettable‑powder formulation of Xtreme Gardening’s pure Rhizophagus intraradices mycorrhizae. This water‑soluble format allows growers to mix the beneficial fungus into water for feeding via hand watering, hydroponic reservoirs, seed treatments, or bare‑root dips. Once applied, MYKOS® WP colonises the root zone and forms an extensive hyphal network to dramatically boost nutrient and moisture uptake. Ideal for both soil-based and hydro systems, MYKOS® WP supports vegetables, fruits, herbs and flowers throughout vegetative and early flowering stages. It enhances root structure, reduces transplant shock, and improves tolerance to drought, heat stress and pathogens, all while working well with synthetic or organic fertilisers. This single‑species formulation contains approximately 250–300 living propagules per gram, ensuring high infectivity and no microbial competition. It’s OMRI‑listed where certified and widely used to build healthier, more resilient root ecosystems that can increase crop yield and secondary metabolism.

AZOS

AZOS is Xtreme Gardening’s nitrogen‑fixing bacterial inoculant, containing Azospirillum brasilense, a naturally occurring diazotroph originally isolated in the Amazon rainforest. Active at approximately 1 × 10⁶ CFU per gram in powder form, it converts atmospheric nitrogen into plant‑available ammoniacal nitrogen and stimulates the release of indole‑3‑acetic acid (IAA), a natural growth hormone that promotes robust root and vegetative development. Especially valuable during early plant establishment, AZOS supports faster rooting, stronger root mass, and sustained vegetative vigour. Often paired with MYKOS® and Xtreme Tea brews, it helps reduce reliance on synthetic nitrogen while enhancing overall plant health and yield.

MYKOS

Xtreme Gardening MYKOS® is a pure, granular root‑zone enhancer composed of the arbuscular mycorrhizal fungus Rhizophagus intraradices. Designed to form a symbiotic network of hyphae around plant roots, MYKOS® drastically boosts nutrient and water uptake, acting as an extension of the root system for more efficient resource absorption. Ideal for both hobbyist and advanced growers cultivating vegetables, fruits, herbs and flowers, MYKOS® promotes vigorous root development, reduces transplant shock, and supports resilience in both heavy clay and sandy media. It is compatible with synthetic and organic fertilisers, as well as all common growing substrates including soil, coco and rock‑wool. With a high concentration of 300 living propagules per gram, this single‑species inoculant ensures strong colonisation without inter‑microbial competition. It helps plants endure drought or heat stress and can improve long‑term soil structure and nutrient cycling.
