Do Si Dos can produce up to 30% THC. After 9-10 weeks of flowering, this relatively large indica can grow into a wide bush. Although not difficult to grow, Do Si Dos cannabis seeds are very popular among growers who have some experience. Especially since the potential with Do Si Dos is so high.

A cross between two giants from the United States: Gelato and Zkittlez. Gives you a wonderfully relaxed and euphoric feeling. Flowers within 8 to 9 weeks and can grow into a behemoth nearly 3 meters long. Growing the Runtz strain doesn't have to be expensive with our brand seeds.
Gorilla Glue
With a THC percentage between 20 and 25%, you can lounge on the sofa enjoying a mental buzz. These Gorilla Glue seeds yield large cannabis plants with a higher than average yield, suitable for both indoor and outdoor cultivation. Due to their short flowering time of 7 to 8 weeks, these are Fast Flowering seeds. But if you grow them outdoors under ideal conditions throughout the summer? You can still cultivate a plant almost two meters tall.
Bruce Banner
Named after the guy who turns into the incredible Hulk, Bruce Banner cannabis seeds have the potential to become a green monster with juicy buds as muscles. After 9-10 weeks of flowering, this compact tree can grow into a broad-leaved monster from which you can harvest 500 grams in October outdoors. It performs at least as well indoors. Especially in a Sea of Green setup where you can collect 800 grams per square meter of buds. Due to its high resistance to mold, it's easy to grow.
Girl Scout Cookies
Girl Scout Cookies or GSC is one of those cannabis strains that you just have to try. If only because it's one of the strongest strains available.
