Harvest the Power of Crystals with ICE from Royal Queen Seeds

Indica Crystal Extreme, better known as ICE, is a masterful hybrid that brings together the legendary genetics of Afghan, Northern Light, and Skunk. This strain was specifically developed for growers looking for unparalleled resin production and iconic indica characteristics. With its rich heritage, ICE offers a stable and powerful growing experience that has been valued in the cannabis world for decades.

Aroma & Effect

As soon as you break open the buds of ICE, you are welcomed by a complex flavor profile of earthy notes, fresh mint, and a subtle hint of pepper and pine. The effect is exactly what you would expect from a high-quality indica: deep physical relaxation that transitions into a classic stoned experience. This cultivar is perfectly suited for quiet evenings when you want to fully switch off and enjoy a happy, calming vibe that puts your body in a state of total rest.

Growth Characteristics & Yield

ICE is known for its compact growth and impressive visual appearance, with the plant becoming completely covered in a shimmering layer of trichomes towards the end of flowering. Indoors, it remains very manageable with a height of around 80-120 cm, while outdoors it can grow into a robust bush reaching up to 2 meters. With a flowering time of 8 to 10 weeks, it produces a very solid harvest of up to 450g/m² indoors and 550g per plant outdoors, making it a favorite among extract and hash enthusiasts.

Growing Tips

To get the most out of your ICE, I recommend applying techniques such as topping and pinching; this forces the plant to spread sideways, creating a wider canopy with more main buds. Because it develops very thick and broad indica leaves, light defoliation can be essential to ensure that light reaches the lower-lying flower sites. If you are aiming for the highest possible resin production for making concentrates, feel free to let the plant stand for up to 10 weeks to allow the trichomes to fully ripen.
