Biobizz Top-Max 0,25 l
The 250 ml bottle is the trial size, covering 60 to 250 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, on any medium, from germination to bloom.
Biobizz Top-Max 250 ml, organic bloom booster
Top-Max is a flowering stimulator. The manufacturer lists three effects: flower size and weight, better nutrient uptake, and a softer, sweeter taste. It is not a fertiliser and does not replace the bloom feed. The 250 ml bottle covers 60 to 250 litres of solution, which makes it the trial size for growers in Belgium and elsewhere in the EU. The feeds it works alongside are listed in the Biobizz catalogue.
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
Where it sits in the schedule
Top Max only comes in at flowering, unlike the supplements that run the whole cycle. It goes alongside the bloom feed in the same watering can and works on what the plant does with that nutrition. Over the final three bloom weeks the dose is four times higher, which is where the product carries most of its work.

FAQ - watering water only
Can Top-Max be sprayed on the leaves?
No. The schedule keeps foliar spraying to three products, Fish-Mix, Alg-A-Mic and Acti-Vera, and Top-Max is not one of them. It goes into the watering water right through flowering: 1 ml/L from bloom week one to five, then 4 ml/L from week six to eight. Because several products from the line can share one can, it mixes in with the bloom feed rather than needing a pass of its own.
