Coastal Seeds Co’s BSHW Columbian is a cross of the Sativa-dominant hybrid Big Sur Holy Weed rumored to be a descendant of Zacatecas Purple, an original Mexican Sativa, and Mazar i Sharif, itself a combination of Afghani and Skunk strains, and Kagyu’s legendary Columbian male.

“Colombian buds have arrowhead-shaped dense minty green nugs with a spattering of fine fiery orange hairs and a thick layer of frosty chunky trichomes and sticky sweet resin. Colombian nugs have an infamous classic aroma of sweet lemon skunk and an equally delicious taste of sweet lemony skunk with a hint of tangy lime upon exhale.”
