Biobizz Pre-Mix 5 l
Pre-Mix is the dry organic fertiliser from Biobizz, mixed into the medium before planting. The 5 L bucket holds 2.5 kg and suits growers in Belgium and elsewhere in the EU who want the feed sitting in the substrate rather than only in the water, in growth and in bloom.
Biobizz Pre-Mix 5 L, the dry base you mix into the medium
Pre-Mix is a dry organic fertiliser that you mix into soil or a soilless medium before planting. The 5 L bucket holds 2.5 kg of organic fertilisers, rock dust, trace elements and fungi. Biobizz makes organic inputs only and uses no mineral salts, so the feed reaches the plant through the soil life rather than straight from the water. The manufacturer lists it as a repotting or starter fertiliser, for growth and bloom, indoors and outdoors.
How to use Pre-Mix
Mix Pre-Mix evenly through the volume of medium you are preparing, then plant and water as usual. Biobizz publishes no dosage for this product, neither on the product page nor on the data sheet, so treat it as an even amendment to the mix rather than a measured dose. That is the practical difference with a bottle: a liquid feed is measured per watering, while Pre-Mix goes in once, before the plant does.
- At repotting: mix into the soil before the plant goes in
- At the start of a run: work it through fresh or reused medium
- Normal watering, no run-off needed
- Move on to liquid feed from 10 to 15 cm, or 2 to 4 true leaves
Certification
Pre Mix carries four certifications: Control Union NOP Input, Control Union Organic EU, EnvirOganic and Soil Association Approved. That set belongs to this product alone. Other bottles in the Biobizz line carry a different combination, so it is worth checking each one instead of assuming the brand covers everything. For growers across the EU the two Control Union marks name a standard instead of a country, which is what makes them readable outside the country of issue.

FAQ - questions about Pre-Mix 5 L
How much medium does one 5 L bucket of Pre-Mix prepare?
There is no published figure and we do not invent one. Biobizz gives no dose per litre for Pre-Mix, neither on the product page nor on the data sheet, so the honest answer is that the bucket holds 2.5 kg of dry fertiliser which you spread evenly through the volume of medium you are mixing. What the label does fix is the format: 5 L, 2.5 kg, EAN 8718403231694. If you want a measured amount per watering, that is what the liquid bottles in the range are for.
Can Pre-Mix go into a pot that is already planted?
It is made for the moment before planting. The manufacturer lists it as a repotting or starter fertiliser, worked evenly through fresh or reused medium so the roots grow into it rather than meeting it later. On a running crop the liquid line takes over instead, from 10 to 15 cm or 2 to 4 true leaves. Repotting itself is the exception: when you move a growing plant into fresh medium, the Pre-Mix goes through that medium first and the plant follows.
