High THC seeds: Prepare for potency

High THC seeds are all the rage in the modern cannabis community. These powerhouses changed the landscape of at-home marijuana growing for good. With these beauties, a strong psychoactive experience is only several puffs away.

With so many hard-hitters on the market, though, growers often find themselves overwhelmed. It’s such a large field to explore, so where do you even start?

We’re here to help. Today, we’re sharing everything you need to know about high THC cannabis seeds. Join our informative journey, get ready to grow strong buds in your garden, and expand your usual repertoire with new must-smoke cultivars.

What is THC?

We’ll start with the basics. Why should you care about high THC seeds in particular?

Tetrahydrocannabinol (THC for short) is the main psychoactive compound in marijuana. This property made it the favorite cannabinoid among 420 communities worldwide. Tokers fell in love with the high, and researchers started unveiling the massive potential of this cannabinoid.

Despite the popularity of THC, research into it is still in its infancy. Here’s what we know about this compound so far.

Our bodies contain endocannabinoid receptors, an internal system that interacts with cannabinoids. We associate these with thinking, memory, sleep, pleasure, pain, coordination, and time perception. Marijuana grown from high THC cannabis seeds activates these receptors.

Upon consumption, chemical reactions in our brains trigger various sensations throughout the body and mind. Smoking marijuana from the highest THC strain seeds delivers a mixture of the following effects:

  • Euphoria and elation
  • Creativity
  • Relaxation (physical and mental)
  • Appetite increase
  • Sleepiness
  • Dizziness
  • Anxiety and paranoia
  • Heart rate increase

Note: This list is far from exhaustive. What you end up feeling depends on the strain, your body composition and tolerance, and many smaller factors.

In general, greater THC levels translate into an amplified high that hits hard and lasts long. You’re likely to feel some effects even with lower cannabinoid doses, but increased potency takes them to the next level.

If you’re not smoking recreationally, high THC seeds deserve a spot on your radar for their medical properties.

What are the health benefits of THC?

Cannabis grown from the highest THC strain seeds isn’t for recreational tokers only. Medical marijuana users have a lot to gain from this compound.

THC alleviates symptoms of various physical and mental conditions. Physicians in legal states prescribe it for:

  • Acute and chronic pain
  • Glaucoma and eye pressure
  • Insomnia
  • Anxiety
  • Nausea and low appetite

Pain-relief and appetite boosting are the most common physical health uses of high THC seed-grown cannabis of indica descent. Sativa mostly helps with fatigue and mental ailments, such as PTSD and anxiety.

What’s more, THC has anti-oxidant and anti-inflammatory properties, helping the body fight off cell damage. It might also inhibit cancer cell growth, assist depressed individuals, and prevent muscle spasms in people with MS.

Many additional health benefits await further research.

Tip: Get high THC seeds with plenty of CBD and terpenes for maximum therapeutic action. All three compounds are helpful in isolation, but they do wonders when combined.

How long does the THC high last?

Much like the effects of your high, its duration is an individual thing. It changes with the strain, your tolerance, and your consumption method of choice.

Most often, a THC high lasts between one and six hours. It persists for longer if you use marijuana from high THC seeds and consume edibles instead of smoking.

Effects of smoking and vaping tend to disappear after four hours. When you ingest cannabis, the figure is somewhere between three and six hours. Of course, some residual effects might linger after you’re generally clearheaded.

What are high THC seeds?

High THC seeds are bestsellers on the marijuana market and the top choice for veteran stoners. They produce cannabis strains rich in THC, guaranteeing a long and powerful high.

How did the highest THC seeds originate?

All cannabis we have on the market today originated from several landrace strains. These marijuana originals made their way into the US in the ‘70s, laying the foundation for the wonders of modern breeding.

Landrace strains were moderately potent, at least by today’s standards. They’d contain below 20% THC, with some staying in the 10–15% range.

Breeders took these cultivars and went to work, crossing and modifying the genomes to increase the THC contents. Endless specimens of high THC seeds were born across the country.

The category of the highest THC seeds incorporates those with levels above 20% of this compound. Some strains take this figure much higher, with over 30% THC.

Note: The expected potency of a high THC cannabis seed is what its genetics allows in ideal conditions. Your growing style and proficiency determine where in that range your buds fall.

In a nutshell, high THC seeds for sale are a very broad category. They encompass a broad scope of THC-rich strains optimized for at-home growing. Purchasing these marijuana seeds sets the genetic stage for the cultivation of potent cannabis.

How to grow high THC seeds?

The right growing techniques for any marijuana garden are strain-dependant. There are some general tips to follow, but research into each cultivar helps you build the ideal growing environment.

Gather information about the following aspects of caring for your highest THC seed-grown crops:

  • Ideal temperature and humidity levels
  • Water and nutrient requirements
  • Ideal light schedules
  • Useful training techniques
  • Potential pitfalls—susceptibility to pests, mold, disease

Tip: Unless your cultivar specifically prefers otherwise, plant in soil instead of hydro. Soil setups promote cannabinoid and terpene production.

If the outside environment doesn’t suit your strain of choice, sow your high THC seeds indoors. That way, you can provide the optimal conditions and prevent the cold, pests, mold, or rainfall from messing with yield quality.

Install powerful grow lights, too. Buds get the stickiest with high light exposure.

You’ll usually see better results with outdoor setups if your climate allows it. Pure sunlight exposure promotes THC content and helps each bud reach its full genetic potential.

Apart from providing proper care to your high THC cannabis seeds, finding the right harvest moment makes a world of difference. Picking the buds too early minimizes cannabinoid contents, while overripe colas lose potency with time.

Where to buy high THC seeds?

These highest THC strain seeds sound delightful, don’t they? If you agree, it’s time to talk about shopping.

Cultivators in the States have two marijuana seed sources at their disposal—physical dispensaries and online seed banks. The former is great, as long as the store nearby stocks strains that piqued your interest. For everybody else, Internet suppliers are the way to go.

You’ll have to practice caution if you decide to go down this route. High THC seeds for sale are hot right now, but it’s still a relatively unregulated market in the US.

Make sure that your shop of choice meets the following criteria:

  • Selection—that’s the main reason you’re not visiting a brick-and-mortar dispensary.
  • Reliability—look for compliances and testimonials and ask around in the global 420 community.
  • Security—we’re talking payment methods, tracking, and shipping. Reviews are a lifesaver for this research phase.
  • Quality—the store should sell high THC seeds that always germinate and grow into healthy marijuana plants. Again, read what your fellow growers had to say.

It doesn’t hurt to look for specific store recommendations, either, especially if you’re struggling with the selection. Seed banks such as Homegrown Cannabis Co. already have industry expert support, cutting your search in half.
