HY-GEN is an Australian nutrient brand built around one idea: give growers exactly what their plants need, at every stage of the grow cycle. From base nutrients and bloom boosters to growing media and pH calibration solutions, HY-GEN covers the full picture, whether you grow in coco, hydro, or soil. Their formulas are built on advanced ion chemistry and backed by decades of grower trust.
๐ฑ Base Nutrients for Coco and Hydro
HY-GEN offers both single-part and two-part base nutrient systems for coco and hydroponic grows. Hydro Growth Formula A & B is a two-part vegetative nutrient engineered for NFT, expanded clay, perlite and other inert substrates, with elevated calcium for strong cell structure and flower retention. For growers who prefer simplicity, HY-GEN Hydro Growth (single part) delivers the same balanced profile in one bottle. The same logic applies to coco: CoCo Grow A & B and Cornucopia Coco-Grow both cover the vegetative stage, available in multiple sizes from 1L to 20L sets.
๐ธ Bloom Nutrients
HY-GEN Hydro Bloom is available as a single-part bottle or a two-part A & B set, both formulated with higher phosphorus and potassium to drive flower and fruit development from flip to harvest. For coco growers, CocoBoom Formula A & B and Cornucopia CocoBloom deliver the same bloom-stage precision, with natural kelp extract and additional calcium to support the root zone and coco medium throughout flowering.
๐งช Additives and Boosters
Budlink Liquid Silica is HY-GEN's flagship additive, the world's original liquid silica supplement since 1997. It embeds into cell walls to build thicker stems, denser canopies and stronger natural resilience, and works as both a root drench and foliar spray across all grow mediums. Sea Essentials is a premium blend of kelp, seaweed and seagrass that promotes bigger flowers, improves fruit quality and encourages beneficial microbes in the root zone. Humiboosta uses humic and fulvic acids to improve nutrient solubility and uptake, with added calcium, magnesium and potassium to keep background nutrient levels topped up from seedling to harvest.
๐งฑ Coco Growing Media
HY-GEN Coco Bricks are available in a 650g brick (expands to 10L) and a 5kg brick (expands to 70L). Both are 100% natural coconut fibre, pre-flushed for low salt content and pre-buffered with calcium and magnesium, ready to use straight out of the bag for hydroponics, seed raising, potting mixes and soil improvement.
๐งช pH Calibration Solutions
HY-GEN pH 4 and pH 7 Buffer Solutions are formulated using analytical grade ingredients under the supervision of a chemist with over 25 years of experience. Used together, they provide a complete two-point calibration for electronic pH meters, ensuring accurate readings across the full pH range your nutrient solution operates in. Available in 250ml, 1L and 5L.
