BioBizz Fish Mix 1L
£13.00 incl. Vat
Fish-Mix has always been a loyal friend for gardeners as it conditions substrates to stimulate bacterial flora and accelerating growth. It is an infusion of organic fish emulsion from the North Sea mixed together with the horticultural extract of Dutch sugar beet.
Fish-Mix boosts growth of all living organisms in the substrate and improves and stimulates production of micro-organisms and useful bacteria in every type of soil and coco. Following the requirements of organic farming, Fish-Mix has not been extracted with acids or stabilized with BHT.
It is mild enough to be used in the first stages of a plant’s life or sprayed directly to leaves during the vegetative stages of growth and the first two weeks of the Fruiting/flowering period. Spraying Fishmix also works wonders on outdoor crops.
