What is THC?

Tetrahydrocannabinol (THC) is the main psychoactive compound in cannabis, put simply; it’s the part that gets people high. The human body contains endocannabinoid receptors in the brain known as CB1 and CB2 which interact with THC once it enters your bloodstream. From there you  will feel your mood, appetite and general perception change as neurotransmitters such as serotonin and dopamine are released to induce feelings of euphoria.

High THC Autoflowering Seeds for Sale

Autoflowering Seeds are favoured by some growers due to the speed at which they reach the flowering stage and also the size of the cannabis plants being much smaller than that of your regular photoperiod marijuana plants. This means they are much better for growers with limited space available to them. Generally, it can be expected that autoflowering seeds produce smaller yields, however, you can find a great selection of high THC strains with great potency that more than makes up for this. Here are some examples of highest THC percentage autoflowering seeds for sale at Homegrown Cannabis Co:

 High THC autoflower seeds are great for first time growers and novices as they are quicker and easier to grow. They also don’t tend to grow to the size of regular or feminized plants, making them ideal for growers with limited space available.

Highest THC Percentage Seeds

High THC levels generally indicates that the cannabis strain will have strong psychoactive effects. There are varying levels of THC even among the highest THC strains, these can produce a variety of effects. Commonly Sativa strains have higher THC levels and make the consumer more energetic whilst Indica strains are more likely to relax you they can still have high levels of THC.


Sativa strains are generally better for recreational use, with sativa dominant high THC strains like Green Crack x Super Silver Haze inducing a strong yet creative and cerebral high which can benefit consumers who are artists, musicians or work creative jobs greatly while also being good for smokers who want to remain active whilst also being high.


While Indica dominant strains like Yumbolt Feminized have the highest THC content (24%) which is well suited to medicinal purposes or general relaxation. Both Sativa and Indica can be used for medicinal purposes with Indica generally having more benefit for physical problems than Sativa.


Many of the strains with the highest THC percentages are hybrids, meaning they exhibit traits of both Sativa and Indica marijuana.

How Long Does the 'High' Last?

Marijuana with the highest THC content is naturally very potent but the effects can vary. The duration of the high largely depends on which of the high THC seeds you choose to cultivate and also how you consume it. 


Take a classic like Gorilla Glue #4 Feminized Marijuana Seeds which is among the highest THC strains of marijuana for sale at Homegrown Cannabis Co.  When smoked or vaped, the high may last for around 4 hours, naturally this can change depending on the quantity you consume. As Kyle Kushman says in his Gorilla Glue Feminized Marijuana Strain Profile, the high is fast acting and can have an extremely positive effect on your mental state. Furthermore, Kyle also picks Gorilla Glue #4 as one of the top high THC cannabis seeds for novice growers.


Here are a few examples of how to consume the highest THC percentage marijuana:

  • Inhalation. Vaporizing or smoking the buds are generally the most popular ways of dosing cannabis with high THC levels. The effects are fast acting - usually within 15 minutes - because the THC goes straight into the bloodstream. However, the high lasts only 2 to 4 hours. It is preferred for casual use, brightening up the day with a puff or two. Also, it is suitable for medical patients who are unable to ingest food or liquids.


  • Ingestion. Making THC edibles is becoming an increasingly popular way of consuming THC. Adding THC to sweets, baked goods or smoothies are just some of the enjoyable ways of dosing. Ingesting THC prolongs the high, meaning it could last for up to 8 hours. This makes it perfect for medical use as it can provide long-lasting relief.


  • Sublingual application. Another widely used method of consumption is dropping small amounts of tinctures under the tongue. The psychoactive effects become apparent after 5 to 10 minutes and can last 2 to 4 hours. It is by far the simplest way of dosing but entails enduring the tincture's bitter taste.

THC Health Benefits

When it comes to THC benefits, often they tend to be overlooked in favour of CBD benefits but THC’s medical benefits are widely recognised. While THC is most known for its psychotropic effects, it also has immense benefits when used as a form of alternative medicine. The highest THC strains in particular are useful when it comes to alleviating physical and mental stress because they can have a relaxing or sedating effect. Take Bruce Banner Autoflower Marijuana Seeds, one of the highest THC strains available, which Kyle Kushman touts as a great alternative to prescription medication when treating mental health issues such as depression, anxiety and PTSD in his Bruce Banner Fast Version Marijuana Seeds profile.

THC impacts the mind and the body which means it is uniquely suited to medicinal use, from THC oil benefits to benefits of the bud itself, THC’s medical benefits are powerful and diverse.


Everyone’s heard of ‘the munchies’ but for people with certain illnesses, lack of appetite can be a real problem. A major THC medical benefit is that it boosts and stimulates appetite which can be crucial in the healing process of illnesses like HIV and even those receiving treatment or therapy for cancer.


THC is naturally occurring which means there is no chemical element to it which means the medical benefits of THC can extend to things like skincare with THC and many other cannabinoids acting as powerful antioxidants. Furthermore, THC can be very helpful when treating a number of different inflammatory problems like arthritis as well as chronic aches and pains.


Look at any of the highest THC cannabis strains available in this section and you will find marijuana strains with the highest THC percentages which can help with a whole host of problems. From minor ailments to chronic illnesses, THC’s medical benefits are both effective and diverse.


Using high THC seeds when growing cannabis at home means that yields will contain significant levels of THC which can then be used medicinally. This means that the bud from strains with the highest THC percentage will last for a longer period when used medicinally as, if there is a higher THC content in each bud, you will not have to consume as much as you would with other strains of cannabis to reap the great medical benefits of THC.


Medical marijuana strains are becoming increasingly popular as alternative medicine or treatment and with good reason.

THC Tolerance

Tolerance refers to how much THC an individual can consume before they become overwhelmed by its effects, this varies from person to person depending on how frequently they consume high THC strains of cannabis, how they consume it, their body mass index (BMI) and also the potency of the cannabis.


Homegrown Cannabis Co. offers a great selection of high THC Seeds for sale which makes it far easier to select which high THC strain is best for you.

Often, the highest THC strains can have great and positive effects, however, it is best to take precautions when starting out so you do not get overwhelmed.


Even veteran cannabis consumers should moderate their THC intake somewhat, while it is impossible to overdose on THC, it’s a good idea to be careful not to consume too much THC so that you can have the most pleasant experience with your marijuana.
