Double Alien 18 crosses the Martian Kush (itself a cross of The OG #18 and Martian Mean Green) back to The OG #18. The result is a shorter-statured plant with very good yields of rock hard buds.

Double Alien 18 is 60% indica taking 9 weeks of flowering to produce harvests of between 550 - 600 gr/m². The flavour is very strongly influenced by The OG #18 with that of the Martian Mean Green being barely detectable on the after-taste. This is a very potent cannabis strain that takes that of Martian Kush to a new level.
