The Black is an incredible indica not for the light-of-heart, thats dates back to the late 1980's in California and on Vancouver Island. This medication is guaranteed to sooth and produce, with crystal coated fan leaves that turn from dark purple to black during flowering. With an instantaneous high and a soothing narcotic nature, The Black makes for a very beneficial night time herb.
I grew some F-13 that was as black as anything I've seen in pics, It was in fact Very, VERY dark purple but you had to look really close to realize it was a shade of purple. I got two like this out of 1/2 pack o beans.
