ICC S1

ICC S1 is a indica cannabis strain with up to 30.0% THC, known for its relaxed effects and bakery and creamy flavor profile.

ICC S1 is a selfed, mostly indica cannabis cultivar created by Green Lion Seeds that aims to bottle the classic Ice Cream Cake experience into seed form. As an S1, it is derived by reversing a selected Ice Cream Cake mother and pollinating it with its own pollen, stabilizing many of the hallmark traits that made the original clone famous. The original Ice Cream Cake genetics trace back to Gelato 33 crossed with Wedding Cake, where Gelato 33 contributes creamy, fruity potency that set trends in the United States, while Wedding Cake provides resinous density, pastry-like aromas, and a deep effect. Green Lion Seeds developed ICC S1 by reversing a prized Ice Cream Cake cut and self-pollinating it, a process typically carried out with silver thiosulfate to inhibit ethylene and induce viable pollen. This S1 strategy preserves key traits like the creamy-dough terpene profile and indica structure while allowing seed growers access to a phenotype previously held as a clone-only.

ICC S1 from Green Lion Seeds is mostly indica, with squat architecture, broad leaves, and strong apical dominance. Internodes are short, which promotes dense cola formation, and calyx-to-leaf ratio is favorable for trimming. ICC S1 plants typically grow squat and compact, reaching 60–100 cm indoors after training, with short internodal spacing that favors dense bud stacking. Its combination of thick calyxes, high trichome density, and sweet, doughy aromatics has made it a favorite in both connoisseur and commercial gardens. Potency commonly ranges from 20–28 percent THCa, terpenes from 1.5–3.5 percent, and density is high with minimal leafy protrusions. Visual uniformity, tight calyx stacking, and strong nose translation from bag to inhale define top-grade ICC S1.
