A UK-made organic fish fertiliser for stronger roots and vegetative growth
Atlantic Fish is Supreme Gardener's organic, hydrolysed-protein fertiliser, made in the UK and built specifically to accelerate how quickly a plant absorbs minerals and salts through the vegetative and pre-flowering stages. It's a liquid additive rather than a full base feed, layered on top of whatever main nutrient programme is already running.
It works across soil, coco and hydro setups, and earns its place through the combination of fulvic acid and a hydrolysed protein base — fulvic acid improves how efficiently nutrients are taken up, while the protein-derived amino acids give the plant raw material to build its own resistance to stress. Growers reach for it when they want to push root mass and general vegetative vigour ahead of the switch to flower, applying it in gradually increasing doses from the seedling/cutting stage through the first month of vegetative growth.
