Maybe it's just the pheno type? Shiva has a sativa pheno that takes longer to bloom then the indica pheno (they always seem to list the best indica flowering time but never list flower times for each specific pheno). I've had the sativa pheno with a number of sensi seed strains but i haven't grown Shiva skunk. All the sativa phenos i got from SS took 12 weeks+ to finish ..i never grew these phenos more then once due to the bloom times
prefer hunting quicker phenos.
