Our substrate sensor
wirelessly measures water content (WC), electrical conductivity (EC) and temperature of many types of growing media.
Our cloud application
provides easy access to all the relevant data in one place. For example, an agronomist can see which crops need irrigation, and which crops need drainage to prevent the damaging effects of overwatering. The cloud application also makes it possible to monitor areas where standing water can compromise the root system and easily detect over-accumulation of salts. This helps to prevent many diseases such as pythium, fusarium etc.
