BioBizz Bio-Bloom - Organic Flowering Feed Built on Sugar Beet Vinasse
Best for: soil and coco growers who want a fully organic bloom-phase feed instead of switching to mineral PK boosters.
Our thoughts
BioBizz built its reputation on keeping things organic without making the feeding schedule complicated, and Bio-Bloom is a good example of that. It's a straightforward bottle-and-water job that does what a bloom feed needs to do, no mixing multiple boosters, no chasing exact PPM numbers.
Bio-Bloom is BioBizz's 100% organic liquid fertiliser for the flowering stage, with an NPK ratio of 1-2-2. The base ingredient is Dutch sugar beet vinasse, a natural fermentation by-product of turning sugar beet or sugar cane into sugar, which supplies the plant with organic nutrition rather than synthetic mineral salts. The low nitrogen level is deliberate: it keeps vegetative growth in check once a plant moves into flower, while the phosphorus and potassium content supports calyx and petal development and helps trigger and sustain the flowering response.
It's designed for use in soil, soilless mixes such as BioBizz's own Coco-Mix, and soil enriched with coconut fibre. BioBizz recommend adding roughly 2 to 4ml of Bio-Bloom per litre of water, used from the start of flowering through to close to harvest.
How it compares
Bio-Bloom competes less on raw feeding power and more on being genuinely organic from top to bottom.
- Vs Canna Terra Flores: Terra Flores is a mineral-based one-part bloom feed with a stronger NPK of 2-2-4, but it isn't certified organic.
- Vs General Hydroponics FloraBloom: FloraBloom is part of a 3-part mineral system that gives more control over exact ratios, at the cost of more bottles to manage and no organic certification.
- Vs synthetic PK boosters like Advanced Nutrients' bloom additives: those are designed to be added on top of a base feed, whereas Bio-Bloom is a complete organic bloom-stage feed on its own.
If organic certification matters to your grow, Bio-Bloom gets you there without extra complexity, though mineral alternatives can push slightly harder on raw PK numbers.
Usage guidance
Simple dosing, but timing matters with an organic feed.
Dosage
Use 2 to 4ml of Bio-Bloom per litre of water at each feed, adjusting toward the higher end for heavier-feeding varieties in later flower.
When to start
Introduce Bio-Bloom from the switch to flowering, tapering Bio-Grow out as you go, and continue until a few days before you flush ahead of harvest.
Pairing
Works alongside Top-Max for an extra PK push in mid-to-late flower, and Acti-Vera if plants are showing any stress.
Before use
Shake the bottle well. Organic bases like vinasse can settle, and a quick shake keeps the feed consistent from top to bottom of the bottle.

Our take
Bio-Bloom does exactly what an organic bloom feed should: enough phosphorus and potassium to drive flowering, low enough nitrogen to keep growth in check, and none of the synthetic mineral salts some growers are trying to avoid.
Does exactly what it should, day in, day out. Worth picking up if you're running the BioBizz range or want a straightforward organic bloom feed.
