Very potent strain.
Double Alien 18 is derived from a cross of The OG #18 and Martian Kush strains to produce an indica dominant variety of cannabis with an award-winning pedigree. DNA's test grows of this strain - conducted in their legal climate - showed shorter than average plants with rock hard buds and larger than average yields.
Double Alien 18 has a very pronounced flavour which leans heavily toward the OG #18 with a hint of the cup-winning Martian Mean Green as an aftertaste. Double Alien 18 is a very potent and flavoursome strain - DNA Genetics have high hopes for competition silverware from this little lady.

Double Alien 18 Feminised Seeds - 6
If you are like me and miss the Martian Mean Green strain, then this is a good substitute. It isn't the soaring MMG high, but it is close, and the body/happy high of the OG#18 is always a welcome addition. It didn't get as big as I thought - maybe taking after the OG more in this case. Other than the size, which can always be addressed with a longer veg time, I had no complaints.
