Blackhawk is a cross of Penis Envy x TAT Black Cap. Crossed by Jik Fibs of T.A.T. Syndicate. The cross resulted in a mushroom which produces multi-pigmented caps. Most caps are tan with a black center, others are all tan, all black, or a mix of pigmentation on the cap. Penis Envy and TBC are both known for their high potency. The mix of the two genetics may have created an even stronger mushroom.
