Serious 6 regular seeds



Serious 6 Regular: Fast-finishing, Made for Outdoors and Harsh Climates

The almost pure Sativa the Serious 6 regular cannabis strain is a mixture of 6 different Sativas from Africa and Canada, made to finish in time and in the harsh Dutch climate - outdoors. An excellent daily strain: colorful, delicious and smelly, a perfect choice for all outdoor growers that aren’t getting long, sunny and warm summers.

Resilient, vigorous and fast finishing, it will finish by the end of September outdoors or after 55-60 days indoors, while there it may prove a bit more challenging to grow and is recommended only for experts as it is difficult getting her to flower inside. Fresh, sweet and flowery aromas will start to spread as soon as the first flowers appear. Half of the phenotypes will have beautiful pink and purple calyxes which makes it a pleasure for all senses. Longer internodes will get filled with dense, large, smelly and sticky buds, providing for a nice yield, usually around 400-550 gr/m2.

  • Suggested nutrients: Advanced Nutrients
  • Recommended techniques: Low Stress Training (LST), Defoliation and Topping
  • Recommended vegetation time for seedlings: 3-4 weeks
  • Usually testing at 15-19% THC with ~1% CBD

Delicious and Relaxing - Great Daytime Strain

Effects of Serious 6 are a strong but super crystal clear cerebral high which will give you energy and creativity to stay active throughout the day. The aroma is complex and built up from layers, with a few obvious notes standing out such as anise, citrus, and spicy flavours.
