Description

Fruity and colourful auto with high THC production.

Purple Punch Auto is the auto-flowering version of Purple Punch, created by the addition of ruderalis genetics to the standard photo-period plant. A high-THC strain.

Indoor-grown plants reach a height of 70 - 90 cm. taking between 60 - 70 days to complete their life-cycle from seed through to harvest time. Yields are in the region of 350 - 400 gr/m². Outdoors, plants grow a little taller at 90 - 110 cm. with harvests possible between April and November in northern latitudes depending on local weather conditions. Buds show some nice purple colours.

A fruity flavour and THC production of 19% make this a potent strain.
