Spore

$349.99

Monitor your grow room's CO₂, humidity, and temperature in real time.

Spore uses an NDIR CO₂ sensor and a precision temperature/humidity sensor, and connects to your local Wi-Fi with an encrypted web dashboard. No cloud account required, nothing phones out, and your data stays local.

CO₂ accuracy by setup

CO₂ readings depend on barometric pressure. The better Spore knows the actual pressure in your space, the more accurate it is.

Standalone (3/5): You enter your altitude or a pressure value during setup.
With Mycelium (4/5): Mycelium pulls local outdoor pressure from OpenWeatherMap (API key required) and sends it to Spore.
With Hyphae or Sentinel (5/5): Spore receives pressure measured in your grow space. Pairing with Hyphae also adds real-time control of CO₂, humidity, and temperature.

Options

Case color: Makes it easy to tell units apart.
LED colors: Red/Green or Yellow/Blue.

Setup details are in the Spore Setup Guide.
