A cross of G13 and Hash Plant, HP13 is a cross-bred hybrid. You may also see it sold as Hash Plant 13, HP-13, Hashplant #13. The effects people mention most are feeling giggly, happy and uplifted.
Public lab results give a good picture of its strength: 3 flower samples tested between 2020 and 2021 came in at a median of 19.2% total THC (the middle half ranged from 18.2% to 19.5%). CBD is typically negligible (under 0.5%). That is in line with most flower on dispensary shelves. Potency varies by grower and batch, so always check the label.
In lab tests its dominant terpene is myrcene, followed by caryophyllene and linalool. Myrcene is known for earthy, musky notes with a ripe-fruit edge, while caryophyllene adds black pepper and warm spice. Total terpene content measured a median of 0.7%. Consumers most often describe the flavour as diesel, chemical and earthy.
Beyond feeling giggly, reviewers also mention feeling euphoric and talkative. The side effects mentioned most are headaches. These are personal reports, not medical advice.
Parents: G13 and Hash Plant. HP13 is also a parent of Pineapple Hash Plant.
