Growing CBD & CBG Cannabis Plants Outdoors

Growing your own hemp plants outside can be a fun and satisfying experience. Whether you are considering a large growing operation or you have a sunny spot in a private yard, balcony or rooftop, you can successfully grow hemp seedlings and clones outdoors.

With the high costs associated with indoor growing, many people choose to grow their own plants outdoors.

Other motivating factors include:

  • Yield: outdoor industrial hemp plants can grow to 15 feet in height, sometimes taller.
  • Quality: some feel that cannabis plants that were grown organically outdoors have a special aroma and flavor.
  • Eco Friendliness: without the electricity needed for indoor growing, cannabis grown outside can have less environmental impact. Also, it’s easier to run an organic cannabis operation outdoors.


The first step in determining the best time for growing cannabis outdoors is understanding your local climate.


Part of your choice of when to plant is understanding seasonal weather patterns in your area. Although cannabis is an adaptable plant, extreme weather could negatively affect your crop.

For example:

  • Sustained temperatures below 55 degrees F can result in stunting or death
  • Sustained temperatures above 86 degrees F can result in growth stoppage
  • High winds and heavy rains can result in plant damage
  • Too much moisture can result in powdery mildew or mold

To get a jump on the season, growers — both from cannabis seeds and clones — often start growing their plants indoors in the late winter and early spring.

Hemp seedlings and clones started indoors need to be hardened off — a process of gradually introducing plants to sunshine and cold nights by moving them outdoors for a portion of the day for a number of days before transplanting.


Another crucial climate-oriented step to successfully growing cannabis outside is understanding the available seasonal daylight in your area. For example, on the longest day of the year (summer solstice):

  • If you live in an area along the Gulf of Mexico, you will have about 14 hours of daylight.
  • If you live in an area along the US/Canadian border, you will have about 16¼ hours of daylight.


Another important climate consideration for maximizing your outdoor yield is choosing the right strain. Some strains are better suited to familiar climates.

For example:

  • Tropical varieties grow better in areas where the length of the day doesn’t vary much throughout growing season. In northern latitudes they tend to flower too late, not producing before they die from cold weather, heavy rain or lack of daylight.

Clones vs Seeds for Growing Outdoors

Although cannabis seeds are well suited for growing outdoors, clones have become increasingly popular.

This popularity can be attributed to, among other  reasons, consistency. Clones are all female plants that exhibit the same characteristics of the original or “mother plant.”

An Important Reminder

Laws, limitations and regulations are different for each state. It is important that you fully understand the legality of growing cannabis in your area before starting any growing operation — small or large — and comply with those rules.
