Chronic Thunder: A Powerful Strain with North American Genetics

Chronic Thunder is an Indica-dominant hybrid cannabis strain brought to you by Barney’s Farm as a cross between two elite cannabis strains; Dr Chronic – a very popular early-2000s cannabis strain with excellent genetics – and Alaskan Thunder Fuck, a North American hybrid with fantastic yields of dense, resinous flowers.

Synonymous with High-Quality Genetics

Chronic Thunder doesn’t take much to grow. Her excellent results are in part due to the well-refined genetics of her parents, particularly Alaskan Thunder Fuck whose name has become synonymous with high-quality cannabis genetics. Like many Indica-dominant cannabis strains, Chronic Thunder is a medium-sized plant with heavy yields of almost 600 g/m2 when grown indoors and a slightly larger 650 g/plant when grown outdoors. Her flowering period is 55 – 60 days and would be ready for outdoor harvest at the end of September. Here is some further information to help you grow this strain:

  • Medium height – CBD Critical Cure reaches a final height of 0.9 – 1.0 m.
  • Max EC of water – 1.6 in veg, up to 2.0 in flower.
  • Water pH; 5.8 – 6.0
  • Recommended lighting: Veg: 300 W CFL, Flower: 600 W HPS.
  • Recommended nutrients: Advanced Nutrients pH Perfect® GROW, MICRO, BLOOM

Crystal-Covered Buds

Chronic Thunder has a fantastic smell and taste. Her buds are large, resinous and very sticky due to her thick coating of trichomes giving her a snowed-on appearance. In addition to her beautiful appearance, Chronic Thunder has a potent effect which often leaves the user glued to their couch in deep relaxation.
