Grow cannabis at home in Oregon: city by city
The same plant behaves differently in every town: frost dates, summer heat and humidity decide when to start, when to move plants outside, and what to watch for in the tent. Here is Oregon, city by city, from NOAA's 30-year weather records.
Oregon home grow rules (as of October 2026)
Adults 21 and over: yes. Plant limit: 4 per household, however many adults live there.
Four adults in one home still means 4 plants in total. Source: OLCC FAQ. Local rules (landlords, HOAs, city codes) can add more; this is a summary, not legal advice.
