Growing cannabis in Temple City: an October that ripens buds well and dries them too fast
A Temple City grow room spends the summer fighting heat, then reaches harvest season in air that finally helps. In 2024, October humidity averaged 51 percent, the lowest of the six months measured, January included, and afternoons that month average about 81°F.
Dry, warm air helps keep bud rot away while the plant stands. After the harvest cut, the same air keeps working on the branches you hang. Is your drying space set up for the weather on the day you cut?
Adults 21 and over: yes. Plant limit: 6 living plants per private residence, however many adults live there.
Locked space, not visible from a public place; cities and counties can set reasonable rules for indoor grows (but cannot ban them) and may ban outdoor grows; a landlord may prohibit growing on a rental. Source: Department of Cannabis Control; conditions: Prop 64 text as passed in 2016 (H&S Code 11362.2 and 11362.45). Local rules (landlords, HOAs, city codes) can add more; this is a summary, not legal advice.
Temple City weather, from flower to the drying line
Think past harvest day. Buds that dry in a few warm, dry days can come out harsher, with a thinner smell, than buds dried slowly. A garage a few blocks off Las Tunas Drive in October can run hot by afternoon, so hang the crop in a cool, dark interior closet or room instead. Hanging whole branches rather than trimmed buds, or running a small humidifier in the room, slows things down.
The heat before that is real. The San Gabriel fire station, 2.9 miles away at 363 feet, averages about 17 afternoons at 90°F in August and about 14 in September, with August highs near 88°F. Move the light period to the night from July through September. A sealed room needs an air conditioner; a tent that breathes the room's air needs strong exhaust.
Summer humidity is moderate, not a threat. The 2024 readings ran 66 percent in June, then 58, 54 and 59 percent through September. A flowering tent can still use a dehumidifier late in a run, mostly to clear the moisture the plants give off themselves. Seedlings and fresh clones tend to do well in that June air.
Winter is short and cool rather than cold. December nights average about 45°F, and the station records roughly one freezing night a year. Run the lamp through the coldest hours and set a seedling mat under young plants. January's 68 percent outdoor reading mostly disappears inside a heated home; only an unheated, damp garage would need a dehumidifier then.

Outdoors in the San Gabriel Valley
California limits each private residence to 6 living plants, however many adults live there, kept locked and out of sight of anyone in a public place. Cities and counties can set reasonable rules for indoor grows, though they cannot ban them, and they may ban outdoor grows. Check Temple City's rules for your address before planting.
Where it is allowed, start photoperiod plants (the kind that flower as nights lengthen) indoors March 4 to 18 and set them out from April 15. Autoflowers run on their own clock, so sow those about a week before they go outside. An October finish ripens in that drier air, but October still averages about 7 hot afternoons, so water deeply and shade the plants on those days.
| Frost | Rare: about 1.2 freezing nights a year |
|---|---|
| Nights stay 50°F or warmer | Mar 11 to Nov 19 |
| Start seeds or clones indoors | Mar 4 to Mar 18 |
| Move plants outdoors | Apr 15 or later |
Temple City grow notes, sealed on your phone
Temple City sits in the San Gabriel Valley, with Arcadia and Alhambra close by. A relative under the same roof, a neighbor across a side yard or a grower friend from the next town over may be curious about how your harvest came out.
Canna GLAP encrypts your grow records on the phone, before any of them reach our servers, locked to a key we cannot open without your passphrase. Anyone who broke into those servers would find records they could not read and no way to unlock them. It protects the journal only: the smell of a drying room still travels, so keep that part discreet yourself.
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.
