Xtreme Auto is an auto-flowering version of Outlaw, the Amnesia x Super Haze cross. The addition of Ruderalis genes was achieved with the co-operation of Spanish seed bank Dinafem which has much experience developing automatic cannabis plants. Auto Xtreme is a high-yielding, sativa-dominant auto which can be grown in almost all environments reaching a maximum height of 150 cm. It has a slightly longer grow-cycle than many auto strains taking up to 85 days from seed to harvest. This extra time is rewarded with the provision of tasty, highly potent and large yields. 150 gr/plant is quite within reach. The high is very energetic and sociable| the earlier the plants are harvested the more cerebral the effect. If a heavier stone is desired then leave the plants to go the full time.
