GrowBase Lite – Compact climate control for efficient indoor growing

The GrowBase Lite is the ideal solution for indoor gardeners who want to control their climate reliably without unnecessary complexity. Despite its compact design, it offers powerful control of temperature, humidity, CO₂ and negative pressure, creating stable conditions for healthy plants and uniform growth.

With two freely configurable sockets and additional control and sensor outputs, you can flexibly integrate numerous devices. The GrowBase Lite is suitable for both EC and AC fans and also supports 0–10V / 1–10V dimmable lights, including a sunrise and sunset function. You can conveniently set all parameters via the clear menu – separately for the day and night phases.

The controller keeps the temperature and humidity at a constant desired level and ensures that odours remain reliably in the grow room thanks to negative pressure control. Developed and manufactured in Germany, the GrowBase Lite impresses with its reliability, precision and ease of use.
