Rockstar Tuna is a mix of Tuna Kush and Rockstar. Tuna Kush is a very potent strain from British Columbia. The Rockstar, a cross between Rockbud and Sensi Star, is a powerful indica-dominant hybrid that delivers strong effects without debilitating sedation. With aromatic notes of spices and grapes, the Rockstar tuna is ideal for relieving physical pain, sleeping disorders and migraines.
