How Allgrow works

Chlorella naturally produces cytokinin and auxin — two of the central growth substances in the plant kingdom. Auxin drives root formation and extension growth. Cytokinin governs cell division and shoot development. The balance between them determines how the plant allocates energy between root and foliage. By supplying them from outside, in small and repeated amounts, Allgrow reinforces signals the plant is already sending itself — rather than replacing them with something new. That is why the effect is about how well the plant builds roots and sets fruit, not about how much extra biomass it receives.

The nutrients in Allgrow are taken up both through the root system and through the foliage. That makes the product useful when root uptake is restricted — during drought, when roots are damaged, or when the soil is temporarily anaerobic. Leaf uptake means the effect can start even when the root system is what is limiting growth — exactly the situation where ordinary fertiliser often struggles to help. Over time, though, it is still the root system that determines how much nutrition and water the plant can draw on its own, and that is where the lasting gain lies.

Little difference is usually visible in the first two weeks. From week three onwards it shows first in the root system, then in bud and fruit formation. Allgrow is not a one-off treatment; it works through regular application across the season. That makes Allgrow the wrong choice if you are looking for a quick fix for a season that is already in trouble. The gain instead comes from building the applications into your ordinary routine, season after season, alongside the fertiliser you already use.

This is the most important thing to understand. In our own trials the lowest doses deliver most of the effect, and high doses do harm. In one tomato trial the number of ripe fruit per plant fell from 29 at 2.5 % to 7 at 4 % — below the control's 21. More is not better. That is why we give both a strength and a ceiling for every crop in the dosage, rather than a range left open to interpretation — and why the independent review of white mustard reached exactly the same dose ceiling, without having seen our own figures (read the review →).
