The Sunshine 4 phenotype that we used for this was very heavy on the Chem 4 traits. She puts on some heavy weight, has great sweet/bleach and chlorine terpene profile, with Blueberry Bubba terpenes on the back-end, and has an amazing structure and efficacy. Sunshine 4 took on a lot of the Chem #4 structure, so expect to get large, spear-shaped colas that will need little to no support to hold up these massive flowers.
Chem Jong-Un should produce some huge, candy-coated fuel towers that test reasonably high, in about the 24-29% THC that should take about 9-10 weeks of flowering time for full maturity. I would train her through a triple-tier trellis so you can manage her vigorous growth, and maximize on your overall yield.
