H&G Bud Xl

H&G Bud XL is a targeted flowering additive formulated to boost flower size, density, and flavour quality during the mid-to-late bloom phase. Using a specialised enzyme blend, Bud XL extracts stored sugars and carbohydrates from older plant tissues and redirects them into developing flowers and fruits. This reallocation of energy enhances blossom weight, increases Brix levels, and improves aroma and taste for a superior harvest. By stimulating natural senescence in ageing leaves and bracts, Bud XL ensures the plant prioritises its energy on reproductive growth rather than maintaining non-essential foliage. This shift not only supports bigger yields but also encourages the development of rich resin profiles and vibrant flower colours. Growers often note improved bud structure and density without compromising terpene content or essential oils. Bud XL integrates seamlessly with hydroponic, coco, and soil-based feeding schedules and is suitable for both hobby and commercial cultivation. Its clean-running, highly soluble formulation ensures compatibility with all nutrient lines and delivery systems, making it a versatile choice for any grower aiming for premium quality results.

Xtreme Gardening

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.

Bio Diesel Nutrients

Bio Diesel Marine CaMg+

Bio Diesel Marine CaMg+ is a potent, marine-derived growth enhancer designed to rapidly correct calcium and magnesium deficiencies while promoting vigorous plant growth. This premium additive is sourced from crustacean deposits found in ancient seabeds, providing naturally chelated forms of calcium and magnesium for superior uptake and fast-acting results. In addition to these core minerals, Marine CaMg+ is enriched with natural nitrogen, boron, trace minerals, and plant-growth-promoting compounds including ocean-derived cytokinins. These cytokinins stimulate cell division and lateral branching, resulting in stronger stems, denser foliage, and improved structural integrity. Marine CaMg+ not only rectifies nutrient imbalances within 24–48 hours but also builds long-term plant resilience against environmental stress, pest pressure, and disease. Its clean, soluble formulation ensures compatibility with soil, coco, and hydroponic systems, and it is equally effective as a root drench or foliar spray. By enhancing nutrient mobility and availability, Bio Diesel Marine CaMg+ supports healthier metabolism, more efficient photosynthesis, and optimal growth rates, making it a powerful ally during intense vegetative development or when plants require extra mineral support.

Plant Mechanics LED Fuel

Plant Mechanics LED Fuel is a late-stage bloom enhancer formulated specifically for use under LED and full-spectrum lighting environments. This precision additive contains a synergistic blend of nano-particles, botanical extracts, biochemicals, and traditional Japanese flower compounds that stimulate metabolic pathways responsible for trichome formation, terpene biosynthesis, and flavonoid production. LED Fuel is designed to counter the unique challenges of modern lighting systems, helping plants utilise spectral light more efficiently during the final five weeks of flowering. By promoting enhanced photosynthetic activity and upregulating key biochemical responses, LED Fuel improves the frostiness, aroma, colour, and flavour profile of ripening flowers, without disrupting pH or leaving unwanted residues. Ideal for growers seeking to finish strong, LED Fuel works seamlessly across soil, coco, and hydroponic setups, delivering a clean, stable formulation that integrates into any nutrient program. It elevates the final expression of your crop by optimising internal plant signalling and supporting light-driven secondary metabolite development.

H&G pH+ Stabil/Osmose

H&G pH+ Stabil/Osmose is a professional-grade pH adjuster and stabiliser formulated specifically for growers using reverse osmosis (RO) water or very soft water sources. These water types often lack carbonate hardness, making them prone to rapid pH fluctuations once nutrients are added. This product not only raises pH but also replenishes essential carbonates to create a reliable buffer, ensuring a stable pH range for up to 10 days. This stability is vital for consistent nutrient uptake, preventing deficiencies, and supporting optimal plant growth. The formula helps protect plants from nutrient lockout caused by unstable pH and improves overall solution performance in hydroponic, coco, and soil systems. It is particularly beneficial for growers running recirculating systems or long-term reservoirs, where maintaining a steady pH is critical. By restoring balance to RO or soft water, pH+ Stabil/Osmose creates a dependable foundation for any nutrient program and reduces the frequency of manual pH adjustments.
