ROI

# Model the payback on your rooms.

Set three numbers and watch what a Grow Sensor PRO system returns. The model is deliberately conservative: a 15 % yield lift, well under what growers report on a first run.

How this is calculated

-   Five runs a year, on a 9 to 10 week cycle.
-   A 15 % yield lift. Growers report up to 50 % on a first run, depending on the pheno. We model under a third of it.
-   One PRO system per 400 sq ft of canopy: the published minimum density, not a recommendation.
-   PRO system at £699 / €799 / $899, shop pricing as of July 2026, region dependent. GrowOps subscription not included.
-   Everything runs in your browser. Nothing you enter is sent or stored.
