- Connection
- RS-485 daisy chain to EnviroSensors, output modules and remote sensors, 1.6 km maximum chain length (expansion available beyond); power input 12/24 V AC or DC with output voltage matching input; full hardware override on every output module
- Sizes
- Up to 8 growing zones per controller · up to 32 of any one module — 32 output modules give up to 320 outputs, alongside 32 nutrient probes and 32 environment sensors · output modules carry 10 relays each
- Best for
- Eight zones on one interface, each managed individually — the step up from a single-zone box when the site has grown into several houses. EnviroSensors read temperature, humidity, light and CO2 (PRO version); remote sensors read nutrient concentration, pH, moisture and temperature. Controls venting, wet wall, hydronic heating, light banks, CO2, dehumidification, shade and blackout curtains, HAF fans and extraction, plus batch dosing to 50 recipes and continuous dosing across 8 reservoirs with up to 10 nutrients and a pH adjuster each. Irrigation runs on accumulated solar radiation, a schedule, or rootzone moisture. Alarms go out by email and text per user, settings back up daily, and four access levels keep staff to their own area. Note: this is the Autogrow MultiGrow, supplied and supported by Micro Grow — remote access is through the Autogrow portal at my.autogrow.com — Powered from the grid — 12/24 V AC input, output voltage matching input.
