Oni Seeds (GMO x Sour Dubb) Black Garlic is a gas lover’s best friend. Small, long, pointy lime-green buds are covered in sandy trichomes and reek of onions, fresh skunk spray, potent garlic, and rubber tires. GMO fans will recognize it immediately, but the Sour Dubb adds a GG4 aspect to it that makes it even more comprehensive. Very potent and heavy hitting, she delivers what would be expected from the lineage. Diamonds are a form of concentrate that have a crystalline structure and tend to be high in THC-a. Diamonds focus on the separation of cannabinoids and terpenes so consumers are left with nearly pure THC. Diamonds can be sold as an isolated product or can be mixed in with terpene "sauce".
