About High Octane
Genetics & strain profile
High Octane is a feminized photoperiod strain. It comes from a gas-forward lineage linked to Chemdawg and OG-style genetics, the High Octane OG line. It is 70% indica and 30% sativa, with high THC, often around 20 to 28% depending on the plant and the grow, and low CBD. It carries our harvest from September badge. Its grow difficulty is moderate, so expect it to need some attention.
It has no reviews yet, so what you read here comes from the breeder’s description and not from customer grows, and we will not claim results beyond that. A photoperiod plant lets you decide when to start flowering, so you control how big it gets first. Our seeds are guaranteed, so if a seed does not come up, contact us.
How High Octane grows
It is a medium-height plant. Indoors it flowers in 56 to 63 days, with 450 to 600 g/m² given good lighting and training. Outdoors it is typically ready in late September to early October, with 500 to 900 g per plant depending on the season and plant size. That is a wide range, so plan around the lower number.
Because it is a photoperiod strain, it needs a change in light hours to flower: grow it under long days while it builds size, then switch to 12 hours of light and 12 of darkness indoors. Plants often stretch when the lights change, so plan your ceiling height before you switch. Start the seed at about 22 to 25 °C in a light, damp medium, water gently and feed lightly, and let the top layer dry between waterings. With moderate difficulty, good lighting and training make the difference. Yields are best cases under good conditions, not promises. Harvest by the trichomes rather than by the calendar. Check your local rules before you plant.
Taste, aroma and effect
Diesel and earth, with a slightly peppery Kush finish. The effect is strong: a euphoric lift followed by deep body relaxation. At 20 to 28% THC, newer consumers should start with a small amount, since effects vary from person to person. Any flowering cannabis gives off a smell, so plan for odour control indoors. For related strains, see Super Critical, Blood Diamond and Larry OG.
