CBD Hemp Plant

What is CBD?

Cannabidiol or CBD is one of hundreds of components of the cannabis plant and the second most prevalent of the active ingredients.

Hemp and marijuana are both members of the Cannabis sativa family and share certain similarities. CBD is the same cannabinoid, regardless of whether it’s found in a high-THC cannabis plant such as marijuana or a low-THC cannabis plant such as hemp.

Cannabidiol (CBD) is extracted from the flowers and buds of hemp cannabis plants. CBD and related cannabinoids like CBG do not produce intoxication. The “high” felt from consuming marijuana flower and other THC-enhanced products is caused by the chemical tetrahydrocannabinol (THC).

One of the primary differences is that industrial cannabis plants farmed for CBD instead of THC generally have 0.3% or less of Δ9 THC, while marijuana plants can have concentrations up to 40% Δ9 THC.

What are the benefits of growing CBD hemp plants?

Industrial hemp is known as The Billion Dollar Crop, because it has hundreds of commercial uses including clothing, biofuel, building materials and paper.

That being said, today CBD hemp oil and smokable flower products are the primary market for hemp growers.

Benefits of growing hemp plants include:

  • The dense growth of industrial hemp plants leaves little room for weeds to grow and compete for nutrients, water, and sunlight.
  • They are generally highly pest-resistant.
  • The hemp plant’s deep tap roots help to protect soil from erosion.
  • Hemp plants are easier to grow using organic methods than most other fibrous crops.
  • Hemp is typically ready to harvest in four months.

What do I need to know to grow my own high cannabinoid strains?


First check the industrial hemp laws in your state. Although CBD is legal in many states, there might legal limits in your state regarding hemp cultivation, transportation, sales and consumer usage.

Choose the Right Variety

If you’re growing industrial hemp with the goal of producing high CBD yields, to get the most out of your investment you’ll want to start with a high CBD producing strain (whether it’s derived from hemp seeds or hemp clones).

Some of the most popular, high-yield CBD flower strains include:

NOTE: These percentages are based on the individual COAs of each strain.

Testing, Testing, Testing!

If you’re growing high-CBD cannabis plants from seed, be sure to lab-test your seeds to ensure the strains are aligned with your goals. Cannabis industry experts suggest performing these tests 3-4 weeks after the seeds sprout. With this step, it’s possible to separate high-CBD plants from those with more THC.

Perform the test by taking a few top nodes from the plant. Be sure they’re dry before they are taken to the lab. The lab will then identify CBD-dominant plants and you can take cuttings from them.

However–you can skip the testing, and ensure that you are growing fully-feminized, lab-tested plants with high CBD and CBG flower yields by purchasing fully vetted, lab certified hemp seeds or clones from a trusted source, such as Clone Connect.

Grow Dense for Big Yields

Because the end products are different than that of marijuana plants, you should be ready to change the way you go about growing your industrial hemp plants.

You’ll want to grow a dense crop by planting the seeds close to each other. A healthy industrial cannabis plant field should consist of hundreds to thousands of CBD hemp plants that are each comprised of one single stalk, with a hemp field that has a planting plan similar to wheat and corn crops.

Other tips for growing a high CBD strain:

  • Ideally, temperatures should be between 72-85͑º F
  • Soil should be warm about 2-inches down into the soil
  • Water less, as opposed to more
  • If you want to test CBD levels, do it 3-4 weeks after seedlings emerge
  • Harvest early (CBD levels breakdown faster than THC levels)

Should I grow from seeds or clones?

When it comes to hemp flower, you cannot tell whether it comes directly from cannabis seeds or clones.

Yet, the process of growing plants into flower is different for both methods, each with their own pros and cons. Before you decide to grow hemp plants from seed or clone, explore each method to determine which is best for you.

To sum up:

  • There are a number of varieties of high CBD strains of hemp available for growers
  • Pick the plant with the CBD and total cannabinoid percentages that best suit your needs
  • Industrial hemp clones are vastly more reliable in delivering the expected CBD ratio than seeds
  • Check your local, state and country laws before planting marijuana or hemp
