they're really worth it, im gonna get heri running again as soon as i have money i wanna spend on genetics, the potency is mind blowing. pre98 bubba is also really good, and actual C99. urkle is a higher yielding and denser version of granddaddy purp, im sure some seed banks have crossed it with one of their strains or they may even have the real strain, its kind of old though so the genetics dont always stick around. tahoe is another im probably gonna try again, if i have a spare room for it maybe, i like something high yielding like white rhino or white russian, fast, really potent and good yielders.
