Permafrost also known as "Blue Permafrost," is a sativa-dominant hybrid marijuana strain bred by Rogue Buds. Permafrost is named for its frosty coat of crystal trichomes and fresh pine aroma. While some believe Permafrost to be the love child of Trainwreck and White Widow, others claim it comes from Kali Mist and Trinity Snow. Permafrost’s relaxing effects are balanced between mind and body. Larger doses demonstrate the strain’s potency: as sensory detail peaks, attention becomes transfixed, and a full-body calm takes over.
