Biobizz Root-Juice 0,25 l
The 250 ml bottle is the trial size, covering 60 to 250 litres of solution across the data sheet range. Root-Juice is a root stimulator built on humic acids and seaweed extract, used in germination and growth, on any medium, and never in flowering.
Biobizz Root-Juice 250 ml for rooting and early growth
Root-Juice is a root stimulator built on humic acids and seaweed extract. The manufacturer reports stronger rooting and faster uptake; it is not a fertiliser and carries no nutrition of its own. The 250 ml bottle covers 60 to 250 litres of solution, the trial size for growers in Belgium and elsewhere in the EU. The feeds that carry the nutrition are listed in the Biobizz nutrient line.
Two figures, two sources
The manufacturer's data sheet gives a general range of 1 to 4 ml/L. The 2025 nutrient schedule puts Root-Juice at 4 ml/L in germination and growth. Both come from Biobizz and they do not contradict each other: the first covers general use, the second gives the figure for those two stages. What would be wrong is presenting the 4 ml/L of the growth stage as a general dose, or the range as a weekly value.
- Germination and growth: 4 ml/L per the schedule
- General use: 1 to 4 ml/L per the data sheet
- Bloom: Root-Juice does not appear in the schedule
- Solution pH between 6.2 and 6.5
A bottle that lasts
Root Juice covers two stages only, where most products in the line run through flowering as well. A narrow window means fewer waterings involved, so a bottle goes further than you would expect from the dose alone. That is why the trial size often sees several starts through.

FAQ - stimulator, not feed
Does Root-Juice replace the growth feed?
No, it carries no nutrition of its own. The manufacturer describes it as a root stimulator built on humic acids and seaweed extract, aimed at stronger rooting and faster uptake. In the schedule it sits on its own line at 4 ml/L through germination and growth, next to the growth feed rather than instead of it. Take that feed away and there is nothing for the stimulator to speed the uptake of.
