Known for being one of the strongest of the OG strains, Fire OG has a strong scent similar to Lemon Pledge and an effect that can last up to 3 hours. With parents of OG Kush and San Fernando Valley OG Kush F3, the THC can be up to 20% with a CBD of 0.36%. The plant has frost covered nuggets with red hairs, giving the appearance that it is on fire–where the name Fire OG comes from. Flowering time is generally 9-10 weeks.
