Measure
Temperature, humidity, VPD, CO₂ and light are sampled continuously per room. One designated primary device per room owns the numbers — no silent substitution from a nearby sensor.
Grow lights · Controllers · AI platform
Growers Republic LED fixtures, Big G controllers and an AI assistant that knows your rooms — one system from the light above the canopy to the record an auditor asks for.
Designed in the USA. Deployed in commercial grow rooms across the USA, Thailand and the EU.
Three things, done properly, instead of a long feature list.
Temperature, humidity, VPD, CO₂ and light are sampled continuously per room. One designated primary device per room owns the numbers — no silent substitution from a nearby sensor.
Lighting schedules, dimming curves and climate setpoints run on the controller itself, so the room keeps its programme even when the network does not.
Every reading, alarm and manual intervention is retained with its timestamp — the evidence base GACP and EU-GMP audits ask for, exportable on demand.
Big G Ai
Ask about a deficiency, a schedule, or which fixture suits a 4×4 tent. Big G Ai answers from our cultivation knowledge base — and inside the app, from your own live readings.
Answers are guidance, not a guarantee of yield or compliance.
LED fixtures and controllers built for grow rooms — specified in plain numbers, not marketing watts.
Compliance
Export-oriented cultivation lives or dies on documentation. Big G keeps the environmental record continuous and tamper-evident, so the growing operation and the quality file tell the same story.
