Growing cannabis in Torrance: the weather holds still, and so does the damp
Torrance weather barely moves. At the Redondo Beach station, 2 miles away, the coolest months average a high of about 66°F and the warmest, August, about 77. A freezing night comes about once a decade, and nights average 45°F or warmer in every month.
The humidity holds still too: 77 to 79 percent in every month measured in 2024, January and June through October. So the useful question here is not when the bad month arrives. It is where your tent gets dry air when none of the measured months had any to offer.
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.
Making dry air for a Torrance tent
An exhaust fan works by swapping the air in the tent for the air in the room. In a garage in Old Torrance open to air that averaged near 78 percent, or a spare room near Torrance Beach with the windows open, the tent starts with damp air, and more fan speed only pulls in more of it. Make dry air instead of importing it: a dehumidifier in the room, or inside a larger tent, set to hold late flower near 45 to 50 percent.
The lamp is on your side. Warm air holds more water, so the same air reads lower humidity once the lights warm it, and with August highs near 77°F a tent has room to run a few degrees warm. The risk is the dark period. When the lamp shuts off, the tent cools toward the room and the humidity climbs, so keep the dehumidifier and the circulation fans running through lights-off.
Heat hardly registers. The station counts about 4 afternoons a year that reach 90°F, and October holds about 2 of them, more than any other month. If your tent already runs near its limit, watch its October highs, when those spells land on late flower.
Winter changes little, with December and January lows near 47°F, and heating dries the air in a warm room. An unheated garage stays cool and damp, so give it a small heater as well as the dehumidifier.
Heater safety: use one with tip-over and overheat shutoff, plug it straight into a wall outlet (not an extension cord or power strip), and keep it a few feet from tent fabric and plants.

Outdoors in Los Angeles County
California lets a private residence keep 6 living plants, however many adults live there, in a locked space that cannot be seen from a public place. Cities and counties can regulate home grows or ban outdoor ones, so read Torrance's code before you plant outside.
Where it is allowed, sow seeds from March 4 through March 18, then set plants out from April 15. Frost does not end the season, and nights hold at 50°F or warmer from March 17 to November 23. Moisture is the limit: buds ripening in September and October sit in air near 77 to 78 percent. If your locked space is a greenhouse, give it vents and a fan, choose open, mold-resistant varieties, and cut a plant early rather than lose it to gray mold.
| Frost | Rare: less than 1 freezing night a year on average |
|---|---|
| Nights stay 50°F or warmer | Mar 17 to Nov 23 |
| Start seeds or clones indoors | Mar 4 to Mar 18 |
| Move plants outdoors | Apr 15 or later |
Keeping a Torrance grow to yourself
Torrance spends a lot of time out on the street. Twice a week the farmers market fills Wilson Park, and the Downtown Torrance Association keeps Old Torrance busy with antique faires, car shows and Torrance Summer Nights. On blocks that close together, a dehumidifier humming in a garage all October is the kind of thing a neighbor asks about. Your notes on that grow do not have to be part of the answer.
Canna GLAP encrypts your grow journal on your phone before anything is uploaded. Break into our servers and you would carry off scrambled grow records with nothing to open them. The humidity settings that finally kept your buds clean belong to you, not to the next grower at the market.
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.
Questions growers in Torrance ask
Do I need a dehumidifier to grow cannabis in Torrance?
For flowering, almost certainly. Humidity averaged 77 to 79 percent in every month measured, so an exhaust fan alone brings in damp air, and a dehumidifier holding late flower near 45 to 50 percent does the real work.
Does it freeze in Torrance?
Hardly ever. The Redondo Beach station averages about 0.1 freezing nights a year, and nights average 45°F or warmer in every month.
When can I plant cannabis outside in Torrance?
Where your local rules allow it, set plants out from April 15 after starting seeds March 4 to March 18. Nights stay at 50°F or warmer from March 17 to November 23, so mold, not cold, decides when to harvest.
