About this strain
After the runaway success of Runtz there was absolutely no other option but to create an autoflowering version of our previous work. This auto manages to deliver the same outstanding package of plant, but in a smaller time frame – just 70 days from seed! Final growing heights of around 120cm can be expected. Yields still pack a punch – with experience and the correct lighting conditions it is possible to push her as far as 600g/m2.  Just like the original, she can bathe away your worries and strife in a sumptuous sea of fruity flavors, with killer buds that are smeared in an intoxicating layer of diverse cannabinoids. We have even managed to preserve some of the outrageous tastes that the original had in this version, so you’ll be able to have the same amount of fun and enjoyment in a much smaller grow window! This balanced yet saucy hybrid will deliver you to another flabbergasting level of relaxation, shattering mental tensions and ensuring you can carry on through your day, protected from any worries or negativity by a halo of positivity.
