L.A. Confidential x X18
It was not intended to be a CBD strain but the old school genetics of L.A. Confidential (pure Afghan) and X18 (pure Pakistani) has led at least one high CBD phenotype to be isolated and grown medicinally.
Tora Bora grows very vigorously with Pakistani dominant structure and hand grenade size flowers that resemble Afghan buds but bigger and looser. The leaves turn purple very early, usually only half way through flowering.
