Stop guessing your reservoir.
If you run a recirculating system and check pH and EC by hand, GrowRoom is built to take that job, keep a record, and tell you early when something drifts.
What you get.
The jobs you do with a pen, a syringe and a notebook, done by the room itself.
See the room
Live air and water readings, with graphs for the last hour, day or week. Includes VPD, which most home controllers leave you to calculate.
Dose from your phone
Ask a pump for a set volume. It confirms before it runs and reports what it delivered. Pumps stay disarmed until you arm them.
Set the routine
Light cycles such as 18/6 or 12/12, fan windows and recurring doses, running on your own time zone.
Hear about it early
Set warning and critical limits per sensor. You are told when the room goes offline as well as when a number drifts.
What you provide.
- 2.4 GHz WiFi with internet. 5 GHz is supported by the gateway's chip but not tested yet.
- A recirculating reservoir. DWC, RDWC, NFT and recirculating drip are the target setups; other systems have not been considered yet.
- Your lights, fans and other equipment. Mains wiring should be done by a qualified electrician.
- Nutrients, pH up and down, and calibration solutions for the probes.
Please note: the controller's RJ45 sockets look like network ports but carry power and control signals. Never connect them to a router or computer.
Not available at first: automatic pH and EC correction, and automatic climate control. Dosing and switching are manual or scheduled. See the roadmap.
