Grush builds zone-based QR tracking systems for any operation — hobby, farm, or business. Put a code where the work happens. Scan when you arrive. The system handles the rest.

No app to download. No password to forget. Just a scan, a log, and the quiet confidence of knowing exactly what happened, where, and by whom.

A small-scale indoor mushroom farm and soil biology product manufacturer in East Riverside, California. Fresh specialty mushrooms direct to restaurants and farmers markets across the Inland Empire.

We also produce MycoSoil Pellets — broadcast-ready saprotrophic fungal amendments for post-fire soil restoration. The only regional producer in Southern California.

A complete operations management system for mushroom farms — built by an active mushroom farmer to manage a real farm. Zone tracking, batch management, harvest logs, and automated transfer alerts.

Also available as hardware: shipping container grow units pre-configured with the zone management system. One container is a farm. Two is a business.
