(1) If you have any current medical condition(s) or any unknown/undiagnosed conditions that might be affected by plants we recommend you avoid contact with them.

(2) Some plants are poisonous so don’t eat them. See here for additional safety guidance.
(3) Some plants have sharp spines so wear protective gloves and glasses to protect against injury.
(4) The ends of some needle electrodes can be sharp so care must be taken to avoid piercing or puncturing skin. Only use if competent to safely insert electrode into plant.
(5) Safely dispose of all waste material.

Which plant species are suitable for measurements
Electrical activity can be detected in lots of species but the following ‘rule of thumb’ may be help
♦  fast growing plants => faster electrical activity
♦  slow growing plants => low frequency of oscillations
For example, beans are fast growing and generate faster electrical signals.
