Origins of the name PhytlSigns

Phyto- or before a vowel phyt-
Combining form
(Botany) Indicating a plant or vegetation:
[from Greek phuton plant, from phuein to make grow]

Collling English Dictionary | Complete and unabridged |12th edition 2014

Phytl Signs is our version of the common English expression “vital signs” but applied to plants.

Just like humans, plants provide signs indicating their health and vitality. We aim to provide tools to help observe and understand plant vitality because, after all, we rely on plants for food, medicine, fibre and fuel. Understanding plants better will help us live more healthily and sustainably.


Vivent is enthusiastic about collaborating with other individuals and organizations active in plant electro-physiology.

Jobs will be posted here soon. Meanwhile sign in if you are interested in collaborating on this exciting process.
