Biobizz Calmag 0,25 l
The 250 ml bottle is the trial size, covering 180 to 830 litres of solution, a figure rounded down. Calmag is only for reverse osmosis or soft water, against a calcium and magnesium shortfall, with separate figures for medium and for hydro and coco.
250 ml calcium and magnesium supplement Biobizz | Shop
Reverse osmosis water and soft water carry almost no calcium or magnesium. Calmag fills that gap: it is a supplement rather than a fertiliser, and it only earns its place with that kind of water or on a lightly fertilised medium. The 250 ml bottle covers 180 to 830 litres of solution, the trial size of the range. The feeds it sits beside are listed under Biobizz plant food.
Two tables, not one
The dose follows the medium, and nowhere else in this line do the two columns diverge this far. In medium, give 0.3 ml/L in weeks 1 to 6, then 0.5 ml/L in weeks 6 to 8 and 0.8 ml/L in weeks 8 to 10. In hydro and coco the same sequence starts at 0.5 ml/L in weeks 1 to 6 and moves to 1 ml/L from week 6. If a deficiency shows anyway, the figure rises to 1.2 ml/L in medium and 1.4 ml/L in hydro and coco.
- Medium, weeks 1 to 6: 0.3 ml/L preventively
- Hydro and coco, weeks 1 to 6: 0.5 ml/L preventively
- Late in the run, weeks 8 to 10 in medium: 0.8 ml/L
- Solution pH between 6.2 and 6.5
When you do not need it
With ordinary tap water, calcium and magnesium are already present and this supplement adds nothing useful. It is the only product in the line whose usefulness depends first on your water and only then on your plant. So check the hardness of your water before ordering rather than after.

Works with

FAQ - when it is worth using
In which situations does this supplement earn its place?
Three, according to the manufacturer: reverse osmosis or soft water, a lightly fertilised medium, and hydro. The table only carries figures for those cases, running from 0.3 ml/L in medium across weeks 1 to 6 up to 1.4 ml/L in hydro and coco late in the cycle. With water that already brings calcium and magnesium, there is no shortfall to fill and the product has nothing to do.
