Useful Seeds was granted permission by Mean Gene from Mendicino, formally of Afficianado Seeds and now under his own label, Freeborn Selections, to release these special F5 beans as a preservation project to the public.

From Useful: “I decided, out of respect, to contact Mean Gene and ask for his blessing to possibly release the f4 to the public. Well, I spoke with him and he gave me his blessings, actually gave me the strain, and said that since I have put so much work/time I could rename it. I will not be doing that, the name will stay the same. Gotta give a big shout out to @meangenefrommendocino for giving me his blessings on keeping this line alive, and allowing me to offer them to the folks that missed out, and also to those that appreciate things that are long gone.”

From Black Lime, also known as “Black Lime Reserve,” is an Indica dominant hybrid strain created through crossing the classic Northern Lights X Purple Kush X Chemdawg Special Reserve strains. This potent bud took 2nd Place overall at the 2014 High Times Cup, and for a good reason – Black Lime is one bud for the ages. The Black Lime high starts with a euphoric and uplifted onset that boosts your mood and leaves you feeling relaxed and happy with a pleasant tingly effect. This tingly body buzz will slowly creep its way through your entire body, leaving you feeling aroused and hopelessly lazy with body-numbing effects. Black Lime buds have small minty green nugs with light amber hairs and a coating of tiny clear crystal trichomes. Like the name suggest, Black Lime has a sweet lime flavor with hints of black pepper and earthy citrus. The aroma is of sweet pine with twinges of pungent peppery earth and a lemony overtone.
