Growing Cannabis in Kansas

Cannabis cultivation, once a topic of underground discussion and illicit activity, has gained significant attention due to the gradual legalization and decriminalization in various parts of the U.S. As with many states, Kansas has its unique set of regulations, climate conditions, and challenges for aspiring cannabis cultivators. This article sheds light on the essential aspects of growing cannabis in the Sunflower State.

Legal Framework

Before diving into the agricultural specifics, it’s crucial to understand the legal landscape surrounding cannabis in Kansas.

Current Legislation

As of the last update in 2021, Kansas has not fully legalized recreational marijuana. Medical cannabis is in its infancy in terms of legislative acceptance, with CBD oil containing 0% THC being the primary legal option for patients with specific qualifying conditions. However, laws can evolve, and it’s crucial for potential growers to be familiar with state regulations, regularly checking for updates to ensure compliance.

Licensing and Regulation

Should cannabis cultivation become more widely permitted in Kansas, the state is likely to require growers to obtain appropriate licenses. This process could be akin to that in other states, involving background checks, detailed farming plans, and often hefty fees. Moreover, the state may also regulate factors such as plant count, size of the growing area, and security measures.

Climatic Considerations

Kansas, located in the heart of the Great Plains, is subject to a continental climate. This means potential cannabis cultivators will face challenges related to extreme temperature variations, precipitation inconsistencies, and the occasional severe weather event.


Kansas experiences hot summers and cold winters. While cannabis plants thrive in temperatures between 70°F and 85°F during the day, summer peaks can exceed this range, potentially causing heat stress. Conversely, the cold winters would make it challenging to grow cannabis outdoors year-round without protective measures.


The state’s average annual rainfall varies, with eastern Kansas receiving more moisture than the west. Depending on the strain, cannabis generally requires consistent watering, so growers in drier regions should be prepared to irrigate more frequently.

Severe Weather

Kansas is part of Tornado Alley. High winds, hail, and tornadoes pose significant threats to outdoor cannabis crops. As such, growers might consider protective structures or choosing to cultivate indoors.

Soil and Land Preparation

Like any other crop, cannabis thrives when given a strong foundation. The soil quality in Kansas is generally fertile, thanks to its prairie heritage.

Soil Type

Loam—a balanced mix of sand, silt, and clay—is ideal for cannabis. Fortunately, large parts of Kansas have loamy soil, which provides good drainage and retains moisture. However, regular soil tests are recommended to assess pH levels and nutrient content.

Nutrient Management

Cannabis plants are heavy feeders. Regularly amending the soil with compost can enhance its fertility. Additionally, a well-balanced N-P-K (Nitrogen, Phosphorus, Potassium) fertilizer can aid growth. Growers should be cautious of over-fertilization, which can harm the plants and decrease yield.

Strain Selection and Planting

Choosing the right strain can significantly impact a grower’s success. Given Kansas’ climate, growers may consider strains that are resilient to temperature fluctuations and potential moisture inconsistencies.

Indica vs. Sativa

Indica strains typically have shorter flowering times and are more bush-like, potentially making them better suited for Kansas’ shorter growing season. Sativa strains are taller and require a longer flowering period. However, each strain has unique characteristics, and hybrid strains might offer a balance between the two.

Planting Techniques

Direct seeding is a common method, but many growers prefer starting seeds indoors and transplanting them outside after the last frost. This method can protect young plants from late spring frosts and give them a head start on the growing season.

Harvesting and Curing

The culmination of a grower’s hard work is the harvest. Proper harvesting and curing techniques are crucial to ensure the final product’s potency and flavor.

When to Harvest

Trichomes, tiny glandular hairs on the buds, give indications of the best harvest time. When a majority of these trichomes shift from clear to a milky white, and some begin to amber, it’s generally the optimal time to harvest.


After harvesting, the buds should be dried in a dark, humidity-controlled environment for about a week. Then, they are typically placed in airtight containers, which are opened periodically to allow moisture to escape, for several weeks. Proper curing enhances the flavor and potency of the cannabis.


While the legal framework in Kansas presents hurdles for potential large-scale cannabis cultivation, the state’s agrarian heritage and fertile soils offer an encouraging foundation. As the legal landscape evolves and if more comprehensive legalization occurs, Kansas could emerge as a vital player in the U.S. cannabis industry.
