Growing cannabis in Buckeye: seven months with 10 or more days at 90°F

Buckeye's heat is not a summer. It is most of the year. At the Litchfield Park station, 15.5 miles away and 1,040 feet up, April brings about 10 days of 90°F heat, and every month after it through October brings at least that many: about 173 such days a year.

That leaves a short, mild gap from November to March. So which part of the year is your grow really planned around?

Running a Buckeye tent from April to October

The shoulder months are the easy ones to underestimate. In April and October the house can feel comfortable while highs average about 86 and 88°F, and a tent runs warmer than the room around it. Put the tent in an interior room the air conditioning reaches, not the garage, and treat April through October as one long cooling season.

The core months leave no cool hours to borrow. July averages a 107°F high and an 81°F low, and August is nearly the same, so a night light schedule helps far less than it does where nights drop off. The air conditioner does the work; the tent's job is to exhaust its own lamp heat into cooled air, never into an attic or a hot garage.

Dryness is the other half. Humidity averages about 19 percent in June and 21 to 27 percent from July through October. Seedlings and clones need a dome or a humidifier just to root, and pots in a warm tent can dry out in a day. The upside: late flower here faces almost no bud rot pressure.

November through March suits a tent best. Highs run about 65 to 78°F and lows about 42 to 51°F, so the house does most of the work, and a heat mat on a cold January night is about all a seedling needs.

Buckeye outdoors: locked, enclosed and out of sight

Arizona allows 6 plants per adult at your primary residence, and 12 per residence with two or more adults, in an enclosed area with a lock that keeps minors out, not visible from public view. Check both before you plant: that the space locks, and that nothing in it shows from public view.

The planting date is April 15, with seeds started indoors from March 4 to March 18. Frost is no concern: the last one usually comes around January 7, and from April 15 to an early first frost on December 6 is about 235 days. Heat is the limit. A plant set out in mid April meets about 25 days of 90°F or more in May and every day of July, so give it afternoon shade cloth, deep pots and water every day. Nights average 50°F or warmer until about November 14, so a strain that finishes late still ripens before the cold.

Last spring frost	Jan 7 in a typical year, Feb 5 to be safe (later only 1 year in 10)
First fall frost	Dec 24 typical, as early as Dec 6 (1 year in 10)
Frost-free season	about 351 days
Nights stay 50°F or warmer	Mar 9 to Nov 14
Start seeds or clones indoors	Mar 4 to Mar 18
Move plants outdoors	Apr 15 or later

A new neighborhood, and a log that stays put

Buckeye has grown fast, with new homes filling in across Verrado, Sundance and the I-10 corridor, and new neighbors can be curious about a fan that hums all summer. What you learned in a 107°F July belongs in a log nobody else opens.

Canna GLAP seals the grow with encryption on your phone before it uploads. Get into our servers and what you would find is a West Valley grow in scrambled form, missing the key that reads it.

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 Buckeye ask

Can I grow cannabis outside in a Buckeye summer?

Only with serious shade and water. Every July day reaches 90°F on average and July nights average 81°F, so plants need afternoon shade cloth, large pots and daily checks. Arizona also requires a locked, enclosed space out of public view.

What is the best time of year for an indoor grow in Buckeye?

November through March, when highs run about 65 to 78°F. From April through October each month brings 10 or more days at 90°F, so a tent then needs a cooled interior room.

Do I need a dehumidifier for a Buckeye grow?

Almost never. Humidity averages about 19 percent in June and 22 percent in October, so the work runs the other way: add moisture for seedlings and clones.
