Karel's Haze
What is the Karel's Haze strain?
Karel's Haze is a hybrid cannabis strain with up to 30.0% THC, known for its cerebral effects and citrus and diesel flavor profile.
Karel's Haze is a sativa-dominant hybrid (70% sativa / 30% indica) developed by Super Sativa Seed Club (SSSC), one of the pioneering cannabis seed companies founded in the mid-1980s in The Hague, Netherlands. This strain represents a cross between Old School Haze and Chem Dog OG Fire (ChemDawg x Fire OG BX3), combining classic Haze genetics with modern OG Kush characteristics. The strain was created by Karel Schelfhout, who maintained the original Old School Haze genetics as a cutting for over thirty years, preserving legendary genetics that trace back to Sam the Skunkman's original Haze and Skunk #1 lines. Karel's Haze produces medium to large plants with vigorous growth and develops characteristic OG-style buds that are round, heavy, and covered in resinous trichomes. The strain exhibits phenotypic variation, with some plants displaying dark green and purple shades while others show bright green coloration. The complex terpene profile creates a layered aroma combining tropical sativa lime, citrus notes, and a distinctive dark, gassy aftertaste reminiscent of diesel fuel. This strain has become particularly popular in Amsterdam coffee shops and Barcelona cannabis social clubs, earning recognition as one of Super Sativa Seed Club's flagship varieties.
