What is THC?

THC is the active ingredient responsible for creating the famed psychoactive effects of pot. Simply put, it’s the stuff that gets you buzzed. Tetrahydrocannabinol (THC) is a naturally occurring chemical compound found in marijuana plants.

If you grow high THC seeds, your plants secrete a sticky resin containing THC and other cannabinoids like CBD.

Historical evidence places THC as one of the oldest hallucinogens that have been around since the first century AD. Ancient civilizations used the psychoactive effects for spiritual enlightenment and believed THC had therapeutic properties. Modern marijuana grown from high THC weed seeds—like Amnesia Lemon fem seeds from SeedSupreme —have much higher levels, are stronger, and come packed with cannabinoids. The THC content is very high, usually over 20%, compared to average strains, which are normally lower.

Most marijuana cultivars contain around 60 chemicals, including terpenes, which are compounds responsible for the unique aromas of different strains. THC and CBD are two of the strongest active cannabinoids. 

Seeds with high CBD ranges have dulled or non-existent psychoactive effects. If you want to get more baked than a biscuit, opt for the high THC seeds with low CBD levels.

The benefits of THC

Choosing the highest THC weed strains comes with many benefits—aside from getting you higher than a hippie on a hot air balloon. Many people believe THC to possess a variety of health benefits in the medical marijuana world, such as: 


  • Anti-inflammatory 
  • Pain-relief 
  • Regulates circadian rhythm 
  • Uplifts mood 
  • Neuroprotective properties 
  • Relieves nausea and increases appetite 
  • Makes you laugh—laughter is the best medicine


THC may act as a strong pain reliever, and consumers use it to treat pain without the side effects of opiates. It may also reduce inflammation, which could help with arthritis and other inflammatory-related diseases.

Medical research has shown that buds from high THC seeds may significantly reduce pain intensity without causing any loss of consciousness or awareness.

Contrary to popular belief that marijuana kills brain cells and makes you stupid, it may actually make you smarter. The buds from high THC cannabis seeds have been shown to stimulate neuron activity and may help with conditions like Alzheimer’s. 

Studies show that THC might help reduce brain inflammation and improve cognitive functions such as memory and learning. THC binds with receptors in our brain that control our feelings like pleasure, pain, moods, and appetite.

One of the infamous effects of potent buds from some THC seeds is known as the munchies. By increasing pleasure hormones, THC makes us crave and enjoy food. When you smoke a marijuana joint, it won’t be long before you’re reaching for your favorite snacks.

This effect of munchies may help relieve nausea and vomiting caused by chemotherapy. Users say it can help increase appetite in people with ailments that suppress the sensation, such as AIDS, hepatitis, eating disorders, and dementia.

It’s easy to underestimate the power of relaxation, but giving your mind a break with a few puffs may help relieve stress. Extreme stress over time can lead to anxiety, depression, and other mental illnesses. 

The highest THC strains may aid in washing away your tension, helping you stay calm. They may prevent panic attacks and anxiety from triggering. Many people report that using marijuana helps them unwind, and a favorite pastime is watching comedy movies while high.

Keep in mind that marijuana affects individuals differently. You may not experience all the benefits listed here, or you could feel them differently. Extensive research on cannabis is ongoing, so take this information with a pinch of salt.


How hard is it to grow extreme THC seeds?

The cultivation experience can be easy or challenging, depending on the strain of THC seeds you choose. 

Protecting the precious resin requires a little extra TLC. When the sticky buds send you soaring through the next dimension, there won’t be any complaints. All it requires is patience and a caring hand

Bear in mind that most extreme THC seeds are hybrids, so always research the growing requirements of the parents and the strain itself. Some cultivars fare better indoors than outdoors or the other way around, and some have additional requirements.

Generally, beginners often steer clear of autoflowers and fast flowering strains, as they don’t leave much time to fix mistakes before flowering. Each strain is unique, so take your time on your cultivation journey and discover many wonderful things.

Getting the most THC from your grow

The most important tip for growing marijuana with more THC is to find excellent quality high THC seeds. You want seeds that produce buds with a thick resin coating and booming THC levels. We stock a wide variety of stabilized cannabis seeds that grow into THC powerhouses.

You need to provide adequate care when growing THC seeds by giving them enough water and nutrients. Make sure the plants enjoy ample light, especially during their flowering stage.

The correct lighting schedule jumpstarts trichome production. Aim for 18 hours daily and 12 hours when blooming. Remember to check the strain information for specific requirements.

When growing high THC cannabis seeds, it’s essential to protect the sticky resin. Harsh climate conditions and a lack of nutrients deteriorate the crystals’ cannabinoid quality. More trichome count gives you higher potency weed.

Ensure you have a shelter or a way to move your plants in cases of extreme weather. If you live in an area prone to harsh weather conditions, grow your crop indoors. Invest in a greenhouse set-up with weather protection and all the lighting and equipment your plants need.

Harvesting at the right time is key for great trichome production and ensuring you get the highest THC count possible. Here’s what to look out for: 

  • Swelling ovaries 
  • Flowers merge into monster colas 
  • A few of the older leaves get a yellow hue v 
  • The buds are incredibly sticky
  • The dank aroma gets stronger even with airflow and filters 
  • At least 70% of the pistils are curled inwards 
  • Trichomes have a milky white appearance


Growing indoors vs. outdoors

The highest THC seeds generally thrive in a Mediterranean climate with temperatures around 65–79℉ and relative humidity between 35% and 45%. Avoid extreme cold temperatures, which can affect the resin quality, and too much heavy rain could wash away crystals. 

If you don’t live somewhere with mostly warm weather, it’s best to grow indoors. There, you’re able to control environmental factors to ensure healthy growth. The biggest challenge with growing high THC seeds indoors is keeping the plants well-ventilated. 

As sticky resin generally coats potent strains, mold and mildew grow easily. Use filters and keep air circulating at all times. Most plants require 20–24 hours of light when vegging for the highest possible THC count.  

Plants need to be well-fed to grow big and strong. Whether growing indoors or outdoors, provide them with all the vital nutrients and water.

Nutrition and water are essential, but light helps form sticky, potent buds. Outdoor growth gives your plants the best chance of being healthy with the highest THC possible. 

Sunlight is the protein shake of lighting options because it gets cannabis plants bursting with plump, juicy nugs. Growing high THC level seeds outside in the sunshine is the best way to get potent buds. 


What is the high like?

THC binds to your body’s cannabinoid receptors to naturally stimulate pleasure hormones and increase sensation. The buds from THC seeds trigger the brain’s reward system to release above-average amounts of dopamine.

This process is what creates THC’s pleasurable and uplifting effects, but cannabis plants don’t naturally make THC. You won’t feel high if you took a bite out of one, but you’d still get a healthy snack.

When you grow high-quality marijuana seeds, your plants produce THCA, which is the inactive variant of THC. To create a ‘buzz,’ it needs to be combusted or decarbed at 230–250°F. This is usually in the form of smoking, vaping, or cooking edibles.

The consumption method when using one of these highest THC strains also affects what the buzz is like. If you smoke or vape, the effects take between 5 and 20 minutes to kick in and last for an average of two hours.

The smoking buzz isn’t as intense as with dabbing or edibles. Consumables take 30–60 minutes to kick in and last for 4–8 hours. The buzz is strong, and the effects linger, making this a popular method for medicinal users.

Different high THC weed seeds produce buds with varying effects, so the type of high is unique to the strain. Typically, THC makes you feel happy, light, and calm. Here are some common effects you can expect from high THC strains:


  • Euphoria 
  • Laughter 
  • Hunger (munchies) 
  • Being amused or enjoying things more than usual 
  • Increased creativity 
  • Extra sensitive to smell, taste, light, sound, and touch
