Growing cannabis in Moreno Valley: the easiest tent months are December through February
Picture a tent in a Moreno Valley garage in January. Days near 67°F, nights near 41°F, and only about 3 freezing days in a whole year at the Redlands weather station, 6.8 miles away at 1,410 feet. Now picture the same garage in August, the hottest month, at about 96°F with roughly 26 days of 90 degree heat.
One of those months is working for you. Which one have you been flowering in?
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.
Indoors: plan the year around the heat
Winter is the gentle season here. From December through February, highs average about 67°F and lows 40 to 42°F. A tent's own lamp does much of the warming in that weather, and the light can run by day. For a spare room off Alessandro Boulevard or a garage in Rancho Belago, these are the months a run is easiest to hold in range.
Summer is the hard part. From June through September the station logs about 85 days that reach 90°F, with highs near 89°F in June, 95°F in July, 96°F in August and 92°F in September. An interior room is the simpler place to grow; a garage needs insulation and an air conditioner. Run the lights at night: July and August nights average about 63°F, so the exhaust pulls in cooler air while the plants sit out the hot hours in the dark.
The air dries as it heats. Humidity averages about 55 percent in June, then 42 in July and 41 in August. Seedlings and fresh clones lose water faster than new roots can replace it, so give them a humid start for two weeks.
By harvest it is drier still. September averages about 49 percent and October about 40, the driest of the months measured, so bud rot pressure is low in a Riverside County flower room. The risk is buds drying too fast after the chop: hang them in a closed tent or closet and let them cure slowly.

Your Moreno Valley outdoor calendar
State law permits 6 living plants for each private residence, no matter how many adults share it. The plants belong in a locked space hidden from any public place, and local governments have the power to regulate home grows, up to banning outdoor ones. Check what the local rules for your address allow before planting in the yard.
Where outdoor growing is allowed, seeds start March 4 to 18 and transplants go outside from April 15. Frost typically ends around January 27 and is nearly always gone by February 28, and fall frost can return as early as December 1. That leaves about 230 days, so heat, not cold, is the limit. Water deeply, give plants afternoon shade through August and September, and vent any enclosure well, since a closed, locked space traps heat.
| Last spring frost | Jan 27 in a typical year, Feb 28 to be safe (later only 1 year in 10) |
|---|---|
| First fall frost | Dec 19 typical, as early as Dec 1 (1 year in 10) |
| Frost-free season | about 329 days |
| Nights stay 50°F or warmer | Apr 30 to Oct 27 |
| Start seeds or clones indoors | Mar 4 to Mar 18 |
| Move plants outdoors | Apr 15 or later |
Keeping a Moreno Valley grow to yourself
A window air conditioner humming in a garage all August is easy to notice, and the person who notices may be standing next to you at the Civic Center Amphitheater for MoVal Rocks or at Taste of the Valley. A roommate, a landlord or a grower down the street may get curious about what you are keeping cool.

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 Moreno Valley ask
Does it freeze in Moreno Valley?
Rarely. The nearby Redlands station averages about 3 freezing days a year, and the last spring frost typically comes around January 27. Summer heat, not frost, is the real limit for plants here.
How do I keep a grow tent cool in a Moreno Valley summer?
Run the lights at night, when July and August average about 63°F, and cool the room, not just the tent. From June through September about 85 days reach 90°F, so a garage grow needs insulation and air conditioning.
Can I grow cannabis outdoors in Moreno Valley?
Only if local rules allow it. The state permits 6 living plants per residence in a locked space out of public view, and cities and counties may prohibit outdoor grows. Where it is allowed, plant out April 15 or later.
