The Selection Process

Here at Green Unicorn Farms, we spend our days hunting down the most premium strains of hemp flower (in terms of potency, flavor, user experience and price), from experienced and passionate farmers, allowing you access to the best of the best all in one place.

We know that growing really great hemp flower takes a lot of experience and know-how. Everything needs to be perfect from choosing the right seed genetics, through to timely harvesting and proper curing, to ensure that when the flower reaches you, its trichomes are brimming with all of the beneficial cannabinoids and terpenes. A truly great CBD product must be great from soil to body in order to give the best benefits to you as the consumer.

Therefore, every hemp flower strain you will come across at Green Unicorn Farms has been handpicked for the following qualities.

  • Effects – When we talk about the “best CBD flower” we really talk about helping you find the best CBD flower for YOU. Most of us smoke to remedy something, whether physical or psychological, and our mission is to help you find the perfect strain with a terpene profile that helps you reach that goal.
  • Fully Developed Terpene Profileall of our strains offer pungent aromatics and unique, thoroughly enjoyable flavors due to their bold terpenes from the purest sources.
  • Rich Cannabinoid Content – next to each hemp flower strain you will see that we’ve provided you with the total cannabinoids vs CBD %, all of which can be confirmed with third party lab reports. Total cannabinoids contribute to the entourage effect, in which it has been proven that the whole plant effect is greater than the sum of its parts.
  • Moisture Content – we also check the moisture content of each strain to ensure that it’s cured properly, as all too often we’ll see flower that is either too wet or too dry. If the flower has too much moisture in it then it will be more prone to mold and will weigh heavier (meaning you lose out) and if it’s too dry then it will lose potency and flavor (also meaning you lose out).
  • Cleanliness – all of our handpicked CBD nigs are grown using organic farming methods, in clean arable soil right here in the USA, so you can be confident they’re free from pesticides, heavy metals, and any other harmful compounds.
  • Compliance – we also only source from licensed growers and make sure that our CBD flower is fully compliant with the Hemp Farming Act, never containing more than 0.3% delta-9 THC.

CBD Pre Rolls Vs. CBD Flower

You’ll notice that some hemp strains are sold as bags of flower, some as pre rolls, and some are available in both formats. If you’re not sure whether to buy your hemp flower by the bag or roll, let us help by explaining the differences.

Pre Rolls

Our pre rolls are available to buy in packs of two, five, or seven, perfectly rolled 0.75g joints. They offer the ultimate in convenience for both busy and more inexperienced hemp smokers. Whether you don’t have the time to roll yourself, or have yet to learn how, these consistently crafted pre rolls will burn evenly every time and are packaged in handy, reusable joint packs, allowing you to light up on the go.


Our flower is sold in increments of ⅛’s (3.5g), up to 1lb (56g) bags and is better suited to more experienced hemp or cannabis smokers that can already roll their own joints. If you buy bags of flower, then not only will you get more bang for your buck, but it also gives you more freedom on how to smoke it (joint, pipe, or bong, straight or mixed with cannabis).
