Rosey Leena is based in the USA and spends her days thinking about something most people never notice — the air inside a greenhouse. She's part of the team at Biotherm Solutions, where the focus is climate control for cannabis and greenhouse growers. Temperature, humidity, airflow — it all sounds simple until you're the one trying to keep it steady across a whole facility. Rosey likes taking that complicated side of growing and making it something people can actually manage without a headache.
