This strain has its origins in Afghanistan and was naturalized in the mountains of Humboldt County, California, for over thirty years. Later it came to Holland where it achieved fame after winning the 2001 High Times Cannabis Cup.
This is a long held genetic that CBD offers to the old school lovers. Yumbolt despite belonging to the Indica family, it doesn't produce a single bud; it gives branched ones, with broad leaves and a medium flowering time, finishing in almost nine weeks.
We recommend set the 12 hours cycle with a good size, because in the blooming period its growth in height is minimal. It fills the whole plant with buds covered with a thick resin layer, so you can see lots of flowers in the side branches and the central bud too.
