NF1 is a hybrid, high-THC strain with parents that are readily recognized by any cannabis enthusiast: Northern Lights and Chemdawg. The THC content in this strain makes it one of the most preferred modern crosses, as the levels can come in at anywhere from 23 to over 29 percent. As an offspring of two of the most well-known hybrids, NF1 delivers attributes of both famed parent strains as far as experience, taste, and aroma are concerned.
