Formulated for the bloom phase, Bio Bloom supports flower formation and concentrates natural sugars and aromas for a denser, tastier harvest.
Made from plant extracts and natural trace elements, with no synthetic mineral feeds. Ideal for organic growing that respects living soil and its microbial ecosystem.
Just a few millilitres per litre of water are enough. Its liquid formula mixes instantly with no clogged drippers or residue, perfect for beginners and seasoned growers alike.
Designed to work in perfect harmony with the BioBizz range (Bio Grow, Top Max, Root Juice) to cover the entire grow cycle in soil or coco.
As soon as the first signs of flowering appear, usually after the vegetative phase. Gradually increase the dose from 1 to 4 ml per litre depending on plant vigour, and stop roughly one to two weeks before harvest.
Is Bio Bloom suitable for coco coir?Yes. Bio Bloom works equally well in soil and coco fibre. On coco, keep an eye on the pH of your solution (ideally 6.0-6.5) and combine it with the other BioBizz products for complete nutrition.
Do I need to adjust pH with an organic fertilizer?BioBizz fertilizers are designed to naturally stabilise the substrate pH. A check is still recommended: aim for irrigation water between 6.0 and 6.5 to optimise nutrient uptake.
Bio Bloom is the essential ally of any organic indoor grow: denser flowers, preserved aromas and a living substrate, harvest after harvest.
