What are Medical Seeds?

Medical seeds are cannabis seeds specifically bred to produce plants rich in specific cannabinoids and terpenes commonly sought after by medical marijuana patients.

Many medical patients use seeds to grow their own plants at home, which helps them get the desired effects when treating their specific health conditions.

Medical seeds are bred to produce medical-grade marijuana that is high in THC, CBD, or other cannabinoids and terpenes believed to have therapeutic and medical benefits.

How are Medical Seeds Different from Regular Cannabis Seeds?

Although some patients and legislation differentiate between “medical seeds” and “recreational seeds,” at their core, they are all simply marijuana seeds.

Growers typically choose to focus on a few key factors when cultivating medical cannabis seeds, allowing them to produce flower that gives patients the relief they need:

  • THC levels: Medical cannabis seeds may have varying THC levels. Depending on the needs of the patient, that could mean higher or lower concentrations of THC. 
  • CBD levels: Higher CBD levels are common among medical cannabis strains.
  • Varying Effects: The effects of a particular strain may vary depending, in part, on the cannabinoid and terpene ratios. Medical seeds may be bred and selected on this basis.
  • Cost: Cannabis seeds come in a wide range of prices. Because medical seeds are deliberately bred to produce potentially therapeutic plants, these seeds may be more costly than recreational seeds.

Pros and Cons of Choosing Medical Seed

If you’re thinking about using medical seeds for your home grow, consider the following pros and cons of cultivating your own medical marijuana.

Pros of Cultivating Medical Cannabis at Home

  • Long-term savings: While setting up a home grow may be expensive, it can ultimately save you money by growing the appropriate amount of cannabis based on your needs. This may be especially true for those who require high dosages.
  • Quality: Growing your own marijuana from medical seeds can allow you to grow your preferred quality and potency of cannabis.
  • Access to desired strains and effects: By growing your own cannabis you can always have access to the specific strains and effects you want and need.

Cons of Cultivating Medical Cannabis at Home

  • Legality: Depending on where you live there may be strict laws and requirements surrounding the home cultivation of cannabis.
  • Effort: Growing cannabis from seeds can require significant amounts of time and effort, especially if starting from scratch. A great deal of care and consistency is needed to ensure the medicinal plants are of the highest quality.
  • Initial cost: While the long-term cost of a home grow can save money, the initial cost of setting up a grow operation can be expensive.
  • Growth time: It can take several months for a cannabis plant to mature, so growing your own supply from medical seeds requires patience and planning to ensure a steady supply.

How to Choose Medical Seeds to Grow

Many new and passionate home growers wonder, “How do I choose which cannabis seeds to get?”

When choosing medical cannabis seeds there are several factors to consider.

  • Strain: One way to choose the right medical seeds for your needs is to select a strain that you know works well for your condition and delivers the desired effects.
  • Terpenes: The specific terpenes present in a strain can also influence its effects, so consider the terpene profile to determine the right seeds.
  • Recommendations: Reading reviews from other cannabis users can give you an idea of the effects of a particular strain, as well as how it has worked for others.
  • Category of strain: Indica strains are often associated with more body sensation effects, while sativa strains are typically more stimulating. Understanding your specific needs can help narrow down your options.
  • Cannabinoid content and ratio: The ratio of THC to CBD in a strain can influence its effects. Higher THC levels can lead to more psychoactive effects, while higher CBD levels may help offset some effects of THC.

Medical Seeds FAQ

Am I allowed to grow my own medical cannabis seeds? 

This will depend on the laws in your state. In some places, it is legal for medical marijuana patients to cultivate their own cannabis at home, while in others, it is still illegal or restricted. It is necessary to check the laws in your area before growing your own medical cannabis seeds.

Are there feminized medical marijuana seeds? 

Yes, feminized medical marijuana seeds are available. Feminized seeds are bred to produce only female plants, which are the plants that grow psychoactive-producing buds.

Do medical seeds have specific requirements compared to recreational weed seeds? 

Medical seeds, like recreational seeds, may each have different requirements for the conditions they need to thrive. For example, some strains may require a specific temperature range or humidity to grow properly. It is essential to research the particular requirements of the medical seeds you are planning to cultivate.

What is the growing time for medical seeds? 

The growing time for medical seeds can vary depending on the specific strain and growing conditions. On average, it can take 3-4 months for a cannabis plant to mature from seed to harvest.

When should medical seeds be harvested? 

The timing of the harvest will depend on the specific strain and the desired effects. If in doubt, many cultivators harvest the buds when the trichomes (the small, crystal-like structures on the surface of the buds) are mostly cloudy, as this shows that the THC levels are at their highest.

Conclusion

Medical cannabis seeds may not be the right choice for everyone, as home cultivation can be a costly, time-consuming, process with potential legal or bureaucratic obstacles.

However, growing your own plants with medical seeds can be a convenient way to maintain access to your desired strains, ensuring you always have a supply of flower that can deliver your desired effects, potency, and the right quality cannabinoid ratios.
