Biobizz Top-Max 0,5 l
The 500 ml bottle is the standard size, covering 125 to 500 litres of solution across flowering. Top-Max works on flower size and weight and on nutrient uptake, running next to the bloom feed rather than replacing it, from germination to bloom.
Biobizz Top-Max 500 ml for the last weeks of bloom
Top-Max is the flowering stimulator of the line: flower size and weight, better uptake and a softer, sweeter taste, according to the manufacturer. It runs next to the bloom feed rather than in place of it. The 500 ml bottle covers 125 to 500 litres of solution, the standard size for one flowering run. Everything else in the eight-week table sits in the organic Biobizz range.
The step at week six
The Top-Max schedule comes down to two figures. From bloom week one to five, give 1 ml/L. From week six the dose jumps straight to 4 ml/L and stays there through week eight. That step is the only change in the whole table, and it does not depend on the medium: soil, coco and hydro share one column.
- Bloom weeks 1 to 5: 1 ml/L
- Bloom weeks 6 to 8: 4 ml/L
- Week 9: plain water, no feed
- Solution pH between 6.2 and 6.5
Choosing the size
Because Top Max only works across eight weeks, consumption follows the litres you pour rather than the length of the grow. At 500 ml you cover 125 to 500 litres of solution, a full flowering run for most set-ups. The 250 ml bottle is for trying it out; the litre is for several runs one after another.

FAQ - what the maker claims
What exactly does the manufacturer say it does?
Three things: flower size and weight, better nutrient uptake, and a softer, sweeter taste. Those are the maker's own descriptions rather than measured results, and no yield figure is attached to any of them. What is documented is the dosing, 1 ml/L across bloom weeks one to five and 4 ml/L across weeks six to eight, identical on soil, coco and hydro. The bloom feed running alongside is what actually supplies the nutrients.
