After assembling a complete genome from a new breed of cannabis, University of Minnesota and Sunrise Genetics researchers found that high-CBD “hemp” plants have a mostly marijuana genome.

“Over the past decade, we’ve seen a surge in demand for CBD and we wanted to better understand how plant breeders created high-CBD plants to meet rising demand,” said study co-author George Weiblen, who is a professor in the College of Biological Sciences (CBS) and the science director at the Bell Museum.

Published in the journal New Phytologist, the researchers found that high-CBD plants inherit about 90% of their genes from drug-type cannabis and the rest from hemp. Traditionally, cannabis plants are split into two varieties: a drug-type grown for psychoactive or intoxicating properties (i.e., marijuana) and a hemp-type used to make industrial products like fiber.

This indica-dominant hybrid comes from Dieseltonic and Great White Shark. It has a fruity aroma and produces a mellow high, perfect for moments of deep reflection.

Cannatonic went on to receive multiple first-place awards at different Cannabis Cups around the US and has become a mainstay in the breeding world. It is a 50-50 indica-sativa hybrid with a 1:1 THC to CBD ratio. Depending on where you get your seeds, CBD levels can range from 10-19 per cent, while THC levels remain as low as three per cent. It has a piney, peppery flavor and produces a mellow, relaxing high.

It is a short plant that can be grown indoors, outdoors, and in greenhouses, and is ready to harvest in 60-70 days. When grown indoors under ideal conditions, it can produce up to 500 grams per square meter. Outdoors, it can produce 250-400 grams per plant.

This strain grows well both indoors and outdoors and reaches maturity in 60-67 days. These short plants produce a medium yield and have a strong resistance to mold. Pennywise seeds produce four main phenotypes that vary in bud structure and color, but they all produce the same effects. Some phenotypes produce a beautiful purple color. Indoors, you can expect your plants to yield 300-500 grams per 10 square feet. Outdoors, Pennywise will produce 400-500 grams per plant and will be ready to harvest around mid-October.


Harlequin has a reputation for growing into relatively large plants and producing high yields. Outdoors, it can grow to be eight feet tall and produce up to 600 grams per plant. Indoors, these plants yield up to 700 grams per 10 square feet.

Growing high-CBD cannabis is just about the same as growing any other kind of cannabis plant, but there are a few tips that can help you get your CBD levels as high as possible. It’s important to note you cannot raise the CBD levels of any plant higher than is genetically possible. In fact, seeds from the same strain will produce varying CBD percentages. This is why it’s important to keep a mother plant and take cuttings once you find a plant you love. With clones, you’ll get the same CBD levels every time.

Although growing supplies and electricity can be costly when growing indoors, you can grow your plants almost entirely for free outdoors, which will save you plenty of money and give you an abundance of medicine.

Growing Tips for High-CBD Plants

Harlequin and Jack the Ripper have come together to create Pennywise. More than 70 per cent of plants tested have 12-15 per cent CBD with equal parts THC. This indica-dominant strain treats you to a pleasant and calming body high with mild psychoactive effects.

There are plenty of CBD products for sale in stores, but cultivators can easily grow their own high-CBD cannabis plants for medicinal purposes. Monica Mansfield details five of the best strains to grow at home.
