Purple Punch: Hard-hitting Indica-dominant Genetics

Purple Punch Autoflower is an autoflowering cannabis strain available from Seedstockers. Coming about as a cross between two legendary cannabis strains which have given so much to cannabis culture – Granddaddy Purple and Larry OG – to yield a sweet-tasting, hard-hitting Indica-dominant hybrid which leaves very little to be desired.

Excellent All-round Strain

Purple Punch Autoflower grows with apical dominance and has some side-branching which can be controlled using low-stress training and light defoliation. While she grows well with a little training, her autoflowering genetics make her susceptible to stress-induced issues so training techniques should be limited to the low-stress options described previously. Indoor yields for this strain are 400 – 450 g/m2 after just 11 weeks from germination to harvest while outdoors takes a couple of weeks longer but can bring in as much as 500 g/ plant of dense, sticky flowers. Here is some further information to help you grow this strain:

  • Small to Medium height – Purple Punch Autoflower reaches a final height of 0.6 – 0.9 m indoors and up to 1.2 m outdoors.
  • Max EC of water – 1.0 in veg, up to 1.3 in flower.
  • Water pH: 5.8 – 6.0.
  • Recommended lighting: Veg: 300 W CFL, Flower: 600 W HID.
  • Recommended Nutrients: Advanced Nutrients pH Perfect® GROW, MICRO, BLOOM.

Beautiful Purple Hues

Purple Punch Auto is a fast-flowering hybrid autoflower which brings in copious amounts of dense, resin-covered flowers with purple and pale-green hues. Her high THC content gives her a powerful effect and makes her a fantastic strain for recreational and medical users alike with the latter reporting excellent pain relief properties.
