Growing Cannabis in Texas

The cultivation of cannabis in Texas, like in many states across the U.S., is subject to various laws and regulations. Over the years, the stance on cannabis growing in Texas has evolved significantly. This article delves into the legal framework, climate considerations, and best practices for growing cannabis in the state.

Legal Overview: Cannabis Cultivation in Texas

As of the last update in September 2021, the cultivation of cannabis for recreational purposes remains illegal in Texas. However, medical cannabis is allowed under specific circumstances and with strict guidelines.

Medical Cannabis

The Texas Compassionate Use Act, first signed into law in 2015, permitted the cultivation and use of cannabis with low tetrahydrocannabinol (THC) content (0.5% or less) for specific medical conditions. These conditions initially included intractable epilepsy. Over time, the list of qualifying conditions expanded, but it is essential for growers and users to stay updated on the most current requirements.

Licensed dispensaries can grow and sell medical cannabis in the form of CBD oil. For those seeking to become licensed growers, the Texas Department of Public Safety oversees the licensing process, ensuring that growers meet the stringent security and operational standards.

Hemp Production

It’s important to distinguish between marijuana and hemp. The latter contains 0.3% THC or less and is primarily used for industrial purposes. The 2018 U.S. Farm Bill federally legalized the production of hemp, and Texas followed suit in 2019 by legalizing its cultivation. Growers must obtain a license from the Texas Department of Agriculture and adhere to the state’s testing and inspection protocols.

Climate and Geography: Growing Conditions in Texas

Texas boasts diverse climatic zones, from arid deserts in the west to humid subtropics in the east. Understanding these zones is crucial for the successful cultivation of cannabis.

Suitable Regions

The eastern parts of Texas, particularly the Gulf Coast and East Texas regions, tend to have humid subtropical climates with long, hot summers and mild winters. This region is suitable for growing cannabis, provided that growers take measures to protect plants from excessive humidity, which can lead to mold.

Central Texas, with its more moderate climate, can also be conducive to cannabis cultivation, especially during the spring and fall months.

Western Texas, being arid, poses more significant challenges. However, growers can consider indoor cultivation or greenhouse setups to control the environmental conditions.

Watering Needs

Given Texas’ vast size and climatic variations, watering needs will differ significantly across regions. While East Texas gets adequate rainfall, the western and central parts may require irrigation. It’s essential to ensure that cannabis plants receive consistent water, but avoid overwatering, which can cause root rot.

Best Practices for Cannabis Cultivation in Texas

Soil and Nutrients

Texas soil varies from sandy loam to clayey. For cannabis, well-draining soil is ideal. If native soil isn’t optimal, consider using raised beds or pots with a quality cannabis-specific soil mix. Regularly test the soil to ensure it has the right pH level (between 6.0 to 7.0 for cannabis) and adequate nutrients. Nitrogen, phosphorus, and potassium are vital for healthy cannabis growth.

Pest and Disease Management

Like all plants, cannabis is susceptible to pests and diseases. Common pests in Texas include aphids, spider mites, and caterpillars. Regularly inspect plants and consider organic pest control measures if necessary. To combat diseases like mold and mildew, ensure adequate spacing between plants for airflow and monitor humidity levels.


Timing the harvest is crucial for optimizing the potency and yield of cannabis. Monitor trichomes on the buds: when they turn from clear to milky white, it’s time to harvest. Ensure that harvested cannabis is adequately dried and cured to prevent mold growth and optimize flavor.

Future of Cannabis Cultivation in Texas

Given the rapidly evolving landscape of cannabis laws in the U.S., Texas might see changes in the future regarding recreational cannabis cultivation. Prospective growers should stay informed about legislative updates and be prepared to adapt to the state’s dynamic regulatory environment.


While there are challenges to growing cannabis in Texas, with the right knowledge and practices, it is possible to cultivate this plant successfully. As with any agricultural endeavor, understanding the local climate, soil conditions, and legal restrictions is key to ensuring a productive and compliant operation.
