Hemp Cross Pollination | A Frustrating Factor In Growing Cannabis Outdoors
Last month we talked about one of the frustrations with growing cannabis outdoors, bud rot. This month, we dive into hemp crop cross contamination. One of the biggest frustrations with outdoor cannabis cultivation is in the potential for cross contamination with nearby hemp crops. While hemp cross pollination can also occur indoors, it’s most prevalent outdoors. Cross pollination can ruin cannabis crops and convert them into hemp in a matter of three plant generations.
The Difference Between Cannabis and Hemp
First, it’s important to know the difference between cannabis and hemp. Cannabis and hemp both come from the same plant, however the growth and use of each is the determining factor:
- ‘Cannabis’ describes a Cannabis sativa plant that has been bred for its potent glands, known as trichomes. Trichomes contain high amounts of tetrahydrocannabinol (THC), most known for its psychoactive effects.
- ‘Hemp’ describes a Cannabis sativa plant that contains trace amounts of THC. Hemp is used for more industrial uses, such as fiber for clothing and construction as well as for oils and topical ointments.
While cannabis and hemp are derived from the same plant, the properties of each dictate their usage. For cannabis cultivators, hemp cross pollination means less potent THC percentages, altering the end product and its value.
