Mephisto Originals Line

Our Originals Line were the first autos bred from scratch over a period of years beginning in 2011 to launch our company in 2013. We deem these as the first foray by us into the Auto-flower market to shake it up with high quality, specially selected genetics, that are bred with love, care and attention.
They have now formed our own family of genetics, or auto tool box from which we are breeding them to fresh photo-period genetics to keep furthering the development of top shelf automatics for us and the auto-flower movement alike. These strains have become highly regarded by many customers but to us we see them as our classics as we know them through and through. These strains are a minimum of F4 in the process from Non-Automatic to Automatic up to F8.
Customers submitting these varieties for analysis over time has routinely seen numbers over 20% up to 25% (the minimum THC Value we have seen is 15%).
