Hearing the word ‘Chronic Thunder’ can instill fear in one’s heart. It brings out memories of the flashes of dancing lights in the sky as well as the plant’s trichome frosted buds, which allude to its immense potency of up to 20% THC. In moderation, however, it is quite a pleasant strain to smoke for an evening of relaxation.

Its moniker alludes to none other than the famous Chronic and Alaskan Thunder Fuck, the two legends that Barney’s Farm crossed. The latter is a potent Sativa with a creeping onset that delivers a buzz of energy throughout the body after it has settled. Meanwhile, the former is a balanced strain with a worldwide reputation for its amazing grow.

It is sturdy, with thick stalks and branches, and a high resistance against fluctuations in weather. Its high-yielding capacity, including dense buds and huge colas, are heavily influenced by its parent Chronic.
