How it works

How it works

Mode of action

Vidi Parva contains 1% tryptophan, an essential amino acid that triggers the production of auxins. These auxins boost the formation of cytokinins which in turn induce the formation of fine roots and root hairs and promote the uptake of nutrients from the rhizosphere and the release of exudates that support the rhizosphere microbiology.

Visual effect

Longer roots with more branches and root hairs.
