Know which room is drifting before you lose the flush
Understory watches carbon dioxide, humidity and temperature in every fruiting room and tells you which one is going wrong while there is still time to fix it.
A room goes wrong at two in the morning
A stuck damper takes six hours to ruin a flush. Nobody is in the building. The clipboard says everything was fine at six the previous evening, and it was.
Understory pages the on-call number at 01:40, the moment the line leaves the band.
A pink oyster is not a shiitake
Every species holds a different band, and a generic sensor app alarms on one number for all of them. Pick one to see what Understory holds it to.
Carbon dioxide, parts per million
Long stems and small caps mean the carbon dioxide has been high for a day, not an hour.
Four sensors a room, one afternoon
No rewiring and no controller in the loop. The sensors read; Understory watches and calls you. What you already have keeps running it.
Mount four sensors
One at cap height on each of the two longest walls, one at the return, one in the plenum.
Set the band
Pick the species. The bands come loaded, and you can move them.
Name who to call
One number per room, and a second if the first does not answer inside ten minutes.
The flush you stop losing pays for the year
We lost two pink oyster flushes in a year to the same stuck damper. We have not lost one since, and I stopped driving in at weekends to check.
Priced per room, not per seat
Everyone on the farm gets a login. You pay for the rooms being watched.
Everything below, on as many rooms as you have.
- Carbon dioxide, humidity, temperature and vapour-pressure deficit
- Species bands loaded, and yours on top
- Calls out when a room leaves its band
- Lot tracking from spawn run to third flush, kept five years
Four sensors, mounts and the gateway. No contract: stop any month and they stay yours.
- Vaisala GMP252 carbon dioxide probe
- Two humidity and temperature sensors, one differential pressure
- Five-year warranty, calibrated yearly
What growers ask first
Only watch. Understory does not touch your fans, dampers or foggers, which means it cannot make a room worse and it cannot be blamed for a crop. It reads, it judges the reading against the band, and it calls a person. Growers who want control usually already have it and want something independent checking on it.
The gateway keeps recording to its own storage and backfills when the line returns, so the record has no hole in it. Alarms go out over a cellular fallback in the gateway, because an alarm that depends on the same line that just failed is not an alarm.
Yes, per room and per species. The loaded bands are a starting point from published cultivation ranges, not a rule. Most farms move at least one within the first month, usually the vapour-pressure deficit ceiling, because their air handling behaves differently from anyone else's.
Paper tells you what was true when somebody was standing there. Every problem this catches happens when nobody is. The paper record is not wrong, it is just asleep between six in the evening and six in the morning, which is when a damper sticks.
You do. Export the whole history as CSV whenever you want, including after you stop paying. Nothing is aggregated into a benchmark, sold, or used to train anything.
Start with one room
Fit the sensors in your worst room, the one you already worry about. If it has not told you something you did not know inside a month, send them back.
