Strain Description:
KC 33 is a well-balanced hybrid that exhibits sativa-style growth with its tall structure and narrow, light green leaves, while offering the dense bud formation and short flowering time more common in indicas. Outdoor plants can grow as tall as 3.75 metres and deliver huge yields of up to 900 grams per plant. Indoors, plants remain much shorter, capping at around 100 cm, and yield approximately 130 grams per plant. With a flowering time of 6–9 weeks indoors and 8–10 weeks outdoors, KC 33 is relatively quick for a sativa-leaning strain. The buds are thick, sugary, and produce a sharp, lemon-fresh aroma. Its high THC and low CBD levels contribute to a euphoric, energetic effect without a heavy body load.

Growing Information:
KC 33 is an excellent strain for both beginners and experienced growers. Bred to withstand the challenges of outdoor cultivation, it’s highly resistant to mould, pests, and irregular irrigation. Its landrace roots give it the adaptability and hardiness needed for variable climates. While the plant prefers plenty of light, it matures quickly for a sativa and is easy to manage indoors. Outdoors, it flourishes with generous yields and a rich terpene profile. Harvest typically begins in late September and can continue into October.
