Top 3 most potent marijuana seeds

GB The Green Brand has the most potent marijuana seeds on the market, ready to boost your cannabis experience and make you fall in for these powerful-vigorous super seeds that we’ve selected for you. Check them all!

Green Poison

Green Poison by Sweet Seeds is a potent plant that yields plenty of resin and gives an intense mental effect that’ll have you out of it for quite a while. Make sure not to smoke this before doing anything important or else it probably won't go as planned. The most important thing is to enjoy the high!

Magnum

Magnum by Buddha Seeds is a feminized autoflowering strain with clear sativa dominance. It features a fast and vigorous vegetative growth, medium-long internodes and light green thin leaves. Regarding its genetics, although its seed bank does not want to reveal its originating cross, it is widely reckoned that its predecessors must have some Jack Herer or Haze due to its characteristic incense flavors.

Princess Haze XX

Princess Haze XX offers a psychedelic high thanks to its high THC levels, which range between 22-27%, and also due to its perfect indica-sativa balance. Its potent effects come up very sudden after the first drag, creating a pleasant sensation that invites reflection and meditation. Due to its indica aspect, such effects transform into a sense of mental and physical relaxation.

Green Poison F1 Fast Version

Green Poison F1 Fast Version by Sweet Seeds is a hybrid plant that’s 70% indica, although its effect is incredibly sativa with a mental high that will leave you speechless and thoughtless for a while.

This strain is not suitable for growers seeking large yields, but if you are interested in its intense incense aromas, then no other autoflowering cultivar can compare to Auto Jack Herer bulk seeds.

Buy cannabis seeds for medical use

Recent research has shown the different benefits that cannabis has regarding its medical use. Many experts recommend using cannabis for certain medical conditions such as chronic pain, epilepsy, or loss of appetite. However, the most known use that cannabis has is to help treat cancer symptoms. GB The Green Brand has lots of medical cannabis strains for sale.

Girl Scout Cookies

This genetics is almost identical to the original Girl Scout Cookies strain thanks to the fact that it comes from an elite clone that was chosen for its incredible resinous buds and spectacular aroma. The original strain comes from a cross between a Durban Poison and an OG Kush.

Auto White Widow

Auto New York City by Pyramid Seeds is quite an old school strain; it’s a sativa-dominant plant with a short flowering period. If you’re looking to get the most out of this plant, we recommend planting it during the longest, warmest summer days outdoors.
