Alchimia presents here Ultra-sour from TH Seeds, a cannabis strain as potent as tasteful. Very resinous, it is suitable for several medicinal treatments. Find it now among our range of feminized seeds!

This variety is a cross between two high-quality strains, Mk Ultra and Sour Diesel. Mk Ultra was awarded with the first prize for best indica at 2003 High Times Cannabis Cup and with the second one year later, in 2004. Its effect is devastating, and its taste is very intense and long lasting. This strain was used to pollinate a plant that doesn't need presentation, the famous Sour Diesel, a genetics with extraordinary organoleptic features.

This mostly Indica hybrid is harvested after 9-10 weeks of flowering, yielding around 450gr/m2. The effect is strong and intense, while the taste is acid and citric on a bittersweet background.

  • Genetics: Mk Ultra x Sour Diesel
  • Type: Feminized seeds
  • 70 Indica - 30% Sativa hybrid
  • Indoor yield: 450gr/m2
  • Flowering: 60-66 days
