Best Cannabis Strains for Outdoor Growing by U.S. Region 🌱Updated 22 days ago
Choosing an outdoor strain isn't just about picking your favorite genetics. Your local climate and length of the growing season can make a huge difference.
A strain that loves a long, hot California summer may struggle to finish before the cold, wet fall arrives in Maine.
Here are some varieties worth considering based on where you grow.
Northeast 🌲
Maine, Vermont, New Hampshire, Massachusetts, New York, Connecticut & Rhode Island
Northern growers usually have a shorter season, cooler nights, and increasingly wet weather as fall approaches.
Earlier-finishing varieties and autoflowers can be especially helpful here.
Good options include:
Northern Lights Auto – compact, beginner-friendly, and a great option when the season is short
White Widow Auto – fast enough to fit comfortably into many northern summers
Super Skunk – a hardy option that has been successfully grown outdoors in New England
Afghani – an indica favorite worth considering for northern outdoor gardens
Purple Punch – another indica-leaning choice for growers who have enough time to finish before late-fall weather
👉 For someone in Maine looking specifically for an indica, Northern Lights Auto or Afghani would be good places to start.
Mid-Atlantic 🌤️
Pennsylvania, New Jersey, Delaware, Maryland, Virginia & West Virginia
The Mid-Atlantic has a fairly long growing season, but late-summer humidity and storms can become challenging.
Consider:
Northern Lights
White Widow
Granddaddy Purple
Bruce Banner
Girl Scout Cookies Extreme
Photoperiod plants can do very well here, but keeping good airflow around developing flowers becomes especially important as fall approaches.
Southeast ☀️💧
North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, Tennessee & Arkansas
The Southeast offers a long growing season and plenty of sunshine, but growers also have to deal with heat, humidity, insects, and heavy rain.
Good options include:
White Widow
Bruce Banner
Girl Scout Cookies Extreme
Northern Lights
Amnesia Haze Auto
Autos are also useful here because you can finish a crop before the wettest or hottest part of the season.
Midwest 🌽
Ohio, Michigan, Indiana, Illinois, Wisconsin, Minnesota, Iowa, Missouri, Kansas, Nebraska & the Dakotas
Conditions vary quite a bit across the Midwest.
Northern states such as Minnesota, Wisconsin, and Michigan generally benefit from quicker-finishing plants, while Missouri and southern Illinois have considerably more growing time.
Good choices include:
Northern Lights Auto
White Widow
Super Skunk
Blueberry Auto
Granddaddy Purple
Bruce Banner
In the northern Midwest, autos can take a lot of the pressure off trying to finish a photoperiod plant before chilly fall weather arrives.
Southwest 🌵☀️
Arizona, New Mexico, Nevada & surrounding desert areas
Lots of sunshine is great — but extreme heat and very dry conditions can stress plants too.
Look for varieties that enjoy warmth and plenty of sun, such as:
Blue Dream
Bruce Banner
OG Kush
Amnesia Haze
Granddaddy Purple
Zkittlez Auto
During extreme summer heat, afternoon shade and careful watering can sometimes be just as important as the strain you choose.
Mountain West 🏔️
Colorado, Utah, Idaho, Montana & Wyoming
Elevation changes everything.
Growers may have intense sunlight during the day followed by surprisingly cool nights, and frost can arrive earlier than expected.
Good options include:
Northern Lights Auto
Blueberry Auto
White Widow Auto
Afghani
Granddaddy Purple
For higher elevations or particularly short seasons, autos are often the easier outdoor choice.
Pacific Northwest 🌲🌧️
Washington & Oregon
The Pacific Northwest can provide an excellent summer growing environment, but wet fall weather can become the biggest challenge.
Consider:
Northern Lights
Super Skunk
Granddaddy Purple
White Widow
Northern Lights Auto
Earlier harvests can help growers avoid having dense flowers sitting outside through weeks of cool autumn rain.
California & the West Coast ☀️🌴
California growers have one of the widest selections because many areas offer long, sunny growing seasons.
Popular outdoor choices include:
Blue Dream
Granddaddy Purple
OG Kush
Bruce Banner
Girl Scout Cookies Extreme
Amnesia Haze
Zkittlez
If you're in a cooler coastal area, your strain needs may be very different from someone growing inland where summer temperatures regularly climb into the 90s.
Alaska ❄️
That short outdoor season makes autoflowers especially useful.
Consider:
Northern Lights Auto
White Widow Auto
Blueberry Auto
Zkittlez Auto
Because autos don't need the shortening days of fall to trigger flowering, they can finish while the weather is still cooperative.
Hawaii 🌺
Warm temperatures and strong sunshine give Hawaiian growers a very different set of conditions from most of the continental U.S.
Longer-growing and sativa-leaning varieties can be much easier to accommodate here than in northern states.
Options include:
Amnesia Haze
Blue Dream
Bruce Banner
Girl Scout Cookies Extreme
OG Kush
Humidity and airflow still deserve plenty of attention, especially around dense flowers.
Autos or Photoperiods Outdoors? 🌱
If you live somewhere with a short summer or early fall frost, autoflowers can make outdoor growing much easier.
They flower according to age, so you're not waiting for the shorter days of late summer to get flowering started.
Photoperiod plants can take advantage of a longer season and may become much larger, but they need enough good weather remaining after flowering naturally begins.
Your Exact Location Still Matters 📍
These regional recommendations are starting points.
Even within the same state, conditions can be completely different. Coastal Maine isn't the same as inland Maine, just as northern California isn't the same as the desert areas farther south.
Think about:
How long your warm season lasts
When your first fall frost usually arrives
Summer humidity
Rainfall
Daytime and nighttime temperatures
Amount of direct sunlight
Whether you're growing in the ground or containers
If your outdoor season is questionable, choosing a faster autoflower or earlier-finishing strain can give you a much better chance of harvesting before the weather turns.
