RuntzBF Auto #1
Auto-flowering version with very good yields and a fast life-cycle.

Runtz Auto manages to deliver the same outstanding plant results as the Runtz photoperiod strain, but in just 70 days from seed! Final growing heights of around 120 cm. can be expected. Yields are still very good - with experience and the good lighting conditions it is possible to obtain as much as 600 gr/m2.

Just like the original, she will wash away your worries and stresses in an ocean of fruity flavours, with killer buds that are smeared in an intoxicating layer of various cannabinoids.

Even the fabulous flavours of the original Runtz are preserved, so you'll be able to have the same amount of fun and enjoyment in a much faster time frame! This balanced hybrid will deliver you to another amazing 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.

Runtz Auto is 70% indica and was created using Barney's Farm's own Super Auto #1 breeding plant.
