Marsh-mellow, a novel hybrid, was originally bred by Lovin’ in Her Eyes, and isn’t available as feminized seeds. Before we delve into the genetics, we need to bring you up to speed with certain breeding terminology. The designation “F1” refers to the “First Filial Generation”, which is the progeny resulting from a cross between two genetically distinct parental plants. Marsh-mellow is derived from Marshmellow OG, classified as a Bx1 strain. This indicates that the F1 progeny has been backcrossed, denoted as “Bx”, with one of the original parent plants, thereby reinforcing certain desired traits. This particular cultivation of Marsh-mellow features a THC content of 17.5%.
