Y Griega feminized seeds


Strong and Powerful Strain

Y Griega is a 7-time cup winning strain that is known for its powerful Sativa effects. It has the highest THC level of any Medical Seeds strain – giving you an incredible jolt of energy and an overall feeling of relaxation at the same time. Ideal for diseases that require high levels of THC for treatment.

Hazy Y Griega in Your Growroom

This strain is ideally grown in both indoor and outdoor situations. When grown indoors, we highly recommend putting the plant in a SCRoG (Screen of Green) method of growing, in order to make the plants more manageable. By doing this and putting a net over the plants during flowering, the buds and branches will become more organized which is ideal for smaller growing spaces. The buds are very large and extremely resinous. You can expect a total flowering period of around 12-13.5 weeks, with an average yield of around 500 grams per square meter when grown indoors. Outdoors, you should be getting around 500-600 grams per plant of densely resinous buds.

  • Suitable for HST technique
  • Great for 600W HID growing bulbs
  • Suitable for medium nutrient-rich soil
  • Try for 6.5 pH feeding levels

THC Everywhere

This strain provides intense amounts of energy when consumed, whilst somehow remaining calm throughout the whole process, with a mellow and relaxing feel to follow the sudden energy rush. The strain is excellent for users looking for seriously high THC-rich buds.

    • Advantages
      Great smell and taste, beautiful flowers, solids as rocks.
    • Disadvantages
    • General impressions

      Great strain, definitely two different phenotypes. We had more of indica-dominant, grow very fast and strong.
      Takes for sure 60 to 70 days of flowering to get ready, can be push to 80 but you’ll get more like a physical high, perfect for medicine.
