The highest THC seeds - feminized
While we have to iterate that potent weed seeds do not consist of high THC alone, it certainly doesn't hurt either. The following high THC strains seeds all produce THC levels of 30%! It can't get much higher than that. But these high THC strains offer much more than just high THC levels; you will find out sooner rather than later.
As one of our constant best selling seeds, Godfather OG feminized seeds are an absolute powerhouse. Growing a sturdy cannabis plant, this high THC strain can not only be grown in many different environments. She is also very forgiving of mistakes by first-time growers.
As you can expect, Godfather OG weed is not for the novice smoker. While the sour notes of grapefruit, mixed with a slight sweetness, can be enjoyed by anyone, her high THC levels can truly knock you off your socks. Especially if you are sensitive to THC, so take it slow if you are not a veteran in the field of cannabis consumption.
This descendant of Girl Scout Cookies, another high-THC cannabis strain, has clearly exceeded her mother, at least when it comes to THC levels. She is also less sweet, and more floral and fruity, mixed with a pungent earthy flavor, reminisced of typical Kush strains.
Growing Do-si-Dos feminized seeds, you don't have to worry too much about mold, yet she can still be quite challenging to first time growers.

Low-level THC strains are no longer the norm with these ruderalis infused weed plants. High THC autoflowering seeds are the new standard. Don't believe us yet? Just look at the THC levels of the following high-THC cannabis strains.
Just like her photoperiod counterpart is one of the four most potent strains among our feminized seeds, Hellfire OG autoflower seeds are the autoflower strain with the highest THC levels. So if you are looking to buy cannabis seeds that provide an easy-to-grow cannabis plant that grows potent buds, Hellfire OG auto is a great choice.

Super sticky weed fans will love this one. Because with Gorilla Glue autoflower seeds, growing resinous cannabis has become easier, and faster, than ever. While Gorilla Glue feminized seeds are also very doable for beginners, it's nice to know there are options for growers that are just starting out.
Her diverse flavor palette is quite interesting and complex. The aroma is a blend of petrol and woody scents that culminate in a flavor reminiscent of earthy pines. Additionally, you may detect subtle undertones of coffee and chocolate, which perfectly complement the deep and spicy notes, providing a touch of sweetness. However, due to the high THC level, some users have encountered a faint chemical taste.

High THC seeds FAQs
What are high THC seeds?
Tetrahydrocannabinol (THC) is the active component of weed that provides psychoactive effects and also works on the body, after binding to your cannabinoid receptors. A high concentration of THC can undermine physical movement and affect your senses, resulting in impaired coordination. The higher the THC percentage of a strain, the more powerful the effect can be. We say ‘can’ because THC is not the sole component of a wonderful high. There is a full spectrum of cannabinoids, and even terpenes could play a part in creating that high feeling.
That said, it's difficult to measure most (besides CBD) cannabinoids and terpenes in cold hard numbers, so looking at THC levels when buying cannabis seeds is a simple way of finding out how strong your high can be. Just know that everyone’s body is different, and your experience might not always be exactly the same as the next person's.
What are considered high THC cannabis seeds?
If a strain can reach a maximum of more than 21% THC, we consider the cannabis seeds in question 'high THC seeds'. Just beware that getting to this maximum THC level does require you to create optimal growing conditions to your cannabis plants, they usually can't reach those upper levels all by themselves.
Another thing to note is that in most if not all grows, the upper bud, the top cola if you will, will be the flower with the highest THC percentage. So if you want to experience the full power of your new high THC strain, try that bud out first.
