Y Griega from Medical Seeds starts its growth with a spectacular vegetative vigour, making it especially suitable for SCROG setups to control its height.

It differs from other Sativas because Y Griega produces heavy, large and extremely resinous buds, even the flower stems are covered with resin glands.

In a gas chromatographic analysis made by Canna Resort laboratory, Y Griega reached an incredible 27.12% THC level, making it the strongest cannabis strain available in the Medical Seeds catalogue. You can see the exact result of this test under the main picture (click to expand).

The parental selection has been successfully targeted to reach the maximum psychoactivity: this record-breaking THC level has shaken the cannabis scene.

Its flavor is typical of Haze strains, combined with sweet undertones that make it more original. The effect begins with a strong energetic feeling that slowly changes into a state of alert relaxation. Especially recommended for medical users seeking relief from conditions that require high levels of THC, eg. glaucoma.

Flower time of Y greiga 80 to 90 days, this means 80 to 90 days under a flowering light, not counting the vegative state?

Hi Jason, 

Exactly, it means 80-90 days since you switch the photoperiod to bloom.
