Example recordings of Aloe Vera with PhyLink

First c. 20 minutes after inserting electrodes.

Aloe Vera over c. 6 hours.

Recording the cactus electrical signals over several hours/days provided more information than a few minutes.
Inserting electrodes into ‘soft’ cactus without sharp spines (spikes) such as Sansevieria is relatively easy, see below:
