Grow Room CO₂ Enrichment Dashboard

The default band is 800–1500 ppm enrichment during lights-on for photosynthesis-limited indoor grows. Treat it as a sensible starting point — your own specification, regulator, equipment manual or product datasheet sets the authoritative limits, and you can read your true band straight off the worst case those documents allow. Edit the readings against whatever band applies to you.

When light is the limiting factor (strong lighting, healthy plants, good temperature), enriching to ~1000–1500 ppm can lift photosynthesis and yield noticeably — beyond that the returns fade and it's just wasted gas. Crucially, it only helps during lights-on with enough light to use it; enriching a dim or dark room does nothing. Safety: CO₂ displaces oxygen and is dangerous to people at high concentrations, so a sealed enriched room must have a monitor with a high alarm and ventilation interlocks. Set the band for plants here, but treat the high alarm as a life-safety device for anyone entering.

Match the interval to the consequence and the rate of change: where an excursion spoils product or risks safety, log continuously (or as often as you can sample); where it is merely informative, daily or per-shift spot checks suffice. The in-range % and excursion count only mean something if your sampling is regular — sparse, irregular readings hide the excursions between them.

Yes — every reading is stored in this browser's localStorage on your device and nothing is uploaded to any server, which also makes the dashboard usable on sites with strict data policies. For shared, audit-grade records across a team or for regulatory retention, export the values into your own system.
