Growing cannabis in Albany: the hottest month and the dampest from June to October are eight weeks apart
In Albany, one flower cycle can meet two different climates. At the Corvallis weather station, 4.1 miles away, August is the hottest month of the year, with an 84°F average high and roughly a week of 90-degree afternoons. Two months later, October humidity averages 77 percent.
A plant that flowers across those weeks starts with heat stress and finishes with mold pressure. Is your setup built for one of them, or both?
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.
One Albany tent, two kinds of trouble
August sets the first test. Afternoons average 84°F, and a tent in a spare room near Historic Downtown or a garage corner in Linn County adds its own lamp heat on top. August nights fall to about 51°F, which makes them the best cooling you have: run the lights overnight in July and August and let the tent rest dark through the afternoon.
Then the air turns. Humidity averages 53 percent in July, 63 in August, 69 in September and 77 in October. The tent that needed exhaust for heat in August needs a dehumidifier in the room by late September, when buds are at their densest. Set both up before the run starts, not halfway through it.
Give flowers room to breathe. Strip lower growth that never sees light, keep an oscillating fan pushing air through the canopy, and if a plant finishes in October, cut and hang it in a heated room rather than in a damp garage.
Spring is gentle but slow. Seeds start from April 7 to 21, while April lows still average about 40°F. A heat mat under the tray keeps seedlings moving until nights warm up in late May.

Outdoors in Linn County
Oregon allows 4 plants per household, however many adults live there, so a home with three adults still has 4 plants in total. Move plants out on May 19 or later: the typical last frost is around April 17, but the average night stays below 45°F until May 19. Warm nights of 50°F or more only last from about June 27 to August 29.
Nights drop back below a 45°F average after October 1, and one year in ten the first frost arrives by October 5. That leaves about 139 days. Pick plants that finish by late September, before October's damp sets in, and space all four so air moves between them.
| Last spring frost | Apr 17 in a typical year, May 8 to be safe (later only 1 year in 10) |
|---|---|
| First fall frost | Oct 28 typical, as early as Oct 5 (1 year in 10) |
| Frost-free season | about 194 days |
| Nights stay 50°F or warmer | Jun 27 to Aug 29 |
| Start seeds or clones indoors | Apr 7 to Apr 21 |
| Move plants outdoors | May 19 or later |
| Season note | Frost can arrive before mid October here: long flowering plants may not finish outdoors |
Four plants, one set of notes
With four plants per household, every one counts, and roommates or family share the same four. Each run teaches something worth writing down, and those lessons add up faster than you would think.
Canna GLAP encrypts every page of your grow journal on your phone before upload. If someone got into our servers, they would find grow records locked away with no key to open them. Chat about gardens at the Albany Farmers Market or at River Rhythms all you like; your logs stay on your terms.
What is encrypted: your plants, notes, photos, feed logs and harvests. What is not: account details (such as your email, name and plan), a grow name or town if you type one, your team, and your sensors' names. The full list: what a hacker would get.
