Indoor cultivation

Your yield depends on what your canopy actually receives.

Lamp spec sheets lie. HVAC controllers average over the entire room. The only way to know what's happening at the plant is to measure at the plant — and the only way to defend a harvest record under audit is to log every variable, continuously, with no app account or cloud account to lose.

PAR at the canopy, not the lamp

A 1000 W fixture rated for 2.7 µmol/J delivers what your plant actually sees after distance, reflectors, and shading. Yotta measures real irradiance at the leaf — not what the manufacturer claims at one meter on a test bench.

VPD in every corner

One thermostat doesn't capture the dead spot near the dehu return, the cold pocket by the supply duct, or the canopy-level humidity bump under the lights. Four Tempest 200s do.

Compliance + insurance, ready

Tamper-evident, on-device storage means every cycle has an auditable environmental record. Tap, export, attach to the SOP — no portal, no monthly fee, no broken integration to babysit.

Built for the work that drives yield

Light mapping

Two Yottas placed at canopy top and lower tier reveal exactly where intensity drops off. Re-aim a fixture, adjust hang height, or add supplemental lighting based on what the data says — not on a guess.

VPD audit per harvest

Place four Tempest 200s in opposing corners. Log every minute. At harvest, you have a continuous record of whether VPD held inside spec — and if it didn't, exactly when and where it drifted.

Power outage post-mortem

When the lights or HVAC drop out for hours, you need to know whether the genetics survived. The on-device log keeps recording on battery, so you have temperature and humidity readings spanning the entire outage.
