Northern U.S. Grow Calendar
An Outdoor Marijuana Growing Schedule for U.S. Northern Regions
Some U.S. states have made it legal for citizens to grow weed seeds for medicinal and recreational purposes. This development has spurred an interest in outdoor growing since anybody with available land can cultivate a crop. You do not need all of the expensive equipment used by professionals who grow marijuana indoors. All it takes to harvest a healthy crop of outdoor cannabis is seeds or a mother plant and some essential equipment.
You also need to understand the cannabis growing season, which varies according to location. Crops need lots of light, and the amount of sunlight alters throughout the year, as day lengths change. Day lengths in Northern and Southern U.S. areas are different.
To create an accurate growing calendar, you have to understand how much sunlight your plants will get each month of the growing season. The local weather also impacts planting schedules. This article provides an example of a marijuana growing calendar for areas in the Northern parts of the continental U.S. and Alaska.
In Marijuana Cultivation Timing Is Everything
There is no one-size-fits-all marijuana calendar because northern states have a shorter growing season than southern states. For instance, a farmer in Northern California can put plants outside early in the year because the climate is warm enough. A farmer in Washington has to wait until the days provide enough sunlight.
A general rule of thumb is that you can begin planting seeds around the Spring Equinox. By the Summer Solstice, your plants are taller and the days long enough to plant outdoors. As fall approaches, the days shorten, and plants become heavy with bud. You can begin harvesting near the Fall Equinox. Your crop should be dried and cured before the Winter Solstice.
Chart Your Progress for Consistent Results
Although the calendar provided in this article is a useful general guideline, it is a good idea to keep a journal and jot down your plants’ progress each season. Every region has different weather and soil.
According to industry publication Leafly, it is essential to note the progress of plants at each stage. Record soil conditions, how much water crops need, and any complications. Taking notes helps you to make necessary adjustments as each new season begins.
The schedule outlined in this article is a guide that uses averages based on New York, Chicago, and Seattle. Northern areas of the West Coast have warmer springtime averages and cooler summer temperatures. Alaska has the most sun, followed by the Northwest.
The Best Cannabis Strains for Northern Climates
It is possible to grow nearly any cannabis strain in any climate if plants are cultivated indoors for part or all of the season. However, there are a few types that thrive outdoors in colder climates:
- Granddaddy Purple: This strain is a full indica favorite that offers high THC levels but a mild buzz. It is easy to grow and disease resistant.
- Super Skunk: A classic cannabis strain that has been popular for decades. If you grow it correctly, expect up to a pound of bud.
- Blueberry Auto: Autoflowering cannabis automatically switches from the vegetative to the flowering stage without a change in the ratio of light to dark. Blueberry Auto has a fruity flavor and does well in cold climates. If planted early enough, growers can get two runs in a season.
In February, the average day is 9.5 to 11.5 hours long, and temperatures average 22 to 51 degrees. In Alaska, days are 8.5 to 10 hours and temperatures -8 to 12 degrees.
Although it is cold outside, you need to prepare for the upcoming season. Begin by gathering the following supplies:
- CBD or THC seeds for sale
- Soil and any other mediums you plan to use
- Sprays, watering cans, jerrycans, and the rest of the cultivating tools you will need
- Plant nutrients
Suppliers can help you choose the best seeds for your environment. If you want the longest possible growing season, this is an ideal time to begin plants indoors. Around the end of February, create a controlled environment.
Build a cozy home for plants that provides fresh air, 18 hours of sunlight each day, and warmth. The temperature should stay between 68 and 77 degrees.
February is also an excellent time to prep outdoor soil. The ground may still be too hard in some areas but, if you can work with it, loosen the dirt by adding compost and worms.
By March, the average day is between 9.5 and 13 hours long. Temperatures range from 31 to 54 degrees on average. In Alaska, days are 10.5 to 13 hours long, and average temperatures are 0 to 24 degrees.
Order your pot seeds now and make sure your mother plant is ready if you are going to clone plants.
You can begin spouting plants on windowsills by the end of March. Be sure to first germinate your i49 seeds according to the process laid out in our in-depth germination guide. Also, Be aware of day lengths and ensure they get enough sunlight. March is the month to start sprouting autoflowers as well, so there will be enough time for two successive harvests.
An average April day in the Northern states is 12.5 to 14.5 hours long. Temperatures average 35 to 62 degrees. In Alaska, days are 13.5 to 15.5 hours long and temperatures 24 to 45 degrees.
The middle of April is a time when days are at least 14 hours long in all northern states. That signals the end of artificial lighting. The light from windowsills is enough to sprout weed seeds and keep plants healthy.
Once the danger of frost is past, it is safe to take plants outdoors during the day and bring them in at night. If you are going to clone a mother plant, now is the time.
Days in May are 14 to 15.5 hours long on average. Temperatures range from 52 to 72 degrees. Alaskan days are 15.5 to 17.5 hours long, and temperatures average 40 to 61 degrees.
In most areas, May is the planting season. If you are in doubt about the right time to plant cannabis outdoors, you can follow the rules for tomatoes. They use an almost identical schedule. Authorities at Green Flower also suggest consulting the Farmer’s Almanac for specific planting timeframes.
If you are planting autoflowers, make sure they are sprouting by the second half of May. They need at least three months of warm weather to thrive. In some areas of the country, that represents the entire growing season.
The average June day is 15 to 16 hours long, and temperatures average 54 to 81 degrees. In Alaska, days are 18 hours long, and temperatures range from 52 to 71 degrees.
June is a month of accelerated development for your crop, especially in the third week. autoflower weed seeds will grow faster and develop flowers. Warming temperatures will also cause non-autoflowering cannabis to grow more quickly.
In July, average days are 14-16 hours long, and temperatures are 58 to 85 degrees. Alaskan days last between 16.5 and 18 hours. Temperatures range from 55 to 73 degrees.
Hotter July temperatures cause autoflowering plants to develop significant flower clusters. Non-autoflowers will begin to grow pistils.
Growers who use regular, non-feminized marihuana seeds, should be on the lookout for male plants. Male plants develop flowerheads on the roots of side branches. They look like two tiny balls on a thin stem. Female plants produce drop-shaped calyxes that have two pistils jutting out.
The average August day is now 13 to 15 hours long. Temperatures average 58-84 degrees. In Alaska, days are 14 to 16.5 hour long and temperatures 49 to 66 degrees.
August is the time to harvest autoflowers that sprouted in May. You can do that by cutting off the flower heads and hanging them upside down in a dark place where they can dry. They dry within ten days at room temperature and do not need extra heat. The process is complete if a branchlet cracks when you bend it.
As August nears to a close, the days grow shorter, and only Alaska has 14 hours of sunlight each day. The reduced light triggers non-autoflowers to begin the flowering phase.
In September, the average day is 11.5 to 13.5 hours long, and temperatures average 54 to 76 degrees. In Alaska, days are 11.5 to 14 hours long, and temperatures range from 38 to 55 degrees.
Non-autoflowering plants start developing more flowerheads and pistils in early September. It is essential to keep plants dry during this often chilly and damp time of year. You should also protect marijuana from wind damage. Some growers add a net or use bamboo sticks to ensure plants do not fall over.
October days will last 10 to 13 hours in most northern states, with temperatures averaging 46 to 64 degrees. Alaska days are 11.5 to 14 hours long, and temperatures average 20-33 degrees.
Many plants are blooming by October. It is also a dangerous growing month in the north because the weather can cause bud rot. Scrutinize plants often for bud rot and monitor temperatures since prolonged periods of freezing weather may kill plants.
If your area gets wet and cold in October, keep an eye out for signs of these problems. Begin harvesting before they can damage your crop.
There are many advantages to growing cannabis outdoors in northern regions of the U.S. It doesn’t take a lot of land, is affordable, and requires less equipment than indoor growing. However, you need to follow the right growing schedule for your area. Use professional guidelines to ensure you begin plants early enough, maintain a healthy environment all season, and harvest at the right time.
