A Potent Sativa with Short Flowering Time

This easy-to-grow strain is one of the most popular among growers. Medium in height, it delivers good yields in a short amount of time. It produces a very strong smoke with an intense aroma. The name comes from its powerful effect—often referred to as a 'one hit wonder.' These plants have a shorter flowering period than most sativas, producing compact buds covered in resin crystals.

Genetic Background

Bred from a mix of Columbian, Mexican, Thai, and Afghani genetics, this strain combines the best traits of its parent lines. It is a feminized photoperiod strain best suited for humid and warm climates.

Outdoor Growing Timeline

Photoperiod strains rely on seasonal daylight changes, so harvest timing is closely tied to your local climate.

• Stage 1 - Germination / Early Start: March – April. Wait for frost risk easing and stronger spring light. Watch for cold snaps, slow starts, and excess moisture.
• Stage 2 - Seedling / Transplant: April – May. Wait for milder nights and settled weather. Watch for transplant shock, wind exposure, and pests.
• Stage 3 - Vegetative Growth: June – July. Wait for long days, regular feeding, and healthy expansion. Watch for overcrowding, nutrient issues, and insect damage.
• Stage 4 - Flowering: August – September. Wait for shortening days, dry airflow, and branch support. Watch for mould, botrytis, high humidity, and bad weather.
• Stage 5 - Harvest: Late September – October. Wait for ripe trichomes and dense finished flowers. Watch for autumn rain, rot, and early frosts.

Indoor Growing Timeline

Photoperiod strains give indoor growers more control over size, shape, and when flowering begins.

• Week 0 - Germination: Focus on strong early establishment. Watch for inconsistent starts and excess moisture.
• Weeks 1–2 - Seedling: Ensure stable structure and healthy growth. Watch for stretch and early stress.
• Weeks 3–6+ - Desired Plant Size and Canopy Shape: Wait for desired plant size and canopy shape. Watch for overcrowding, uneven growth, and training stress.
• Weeks 7–12+ - Flowering Phase: Focus on strong flower formation and steady development. Watch for humidity, airflow, and support issues.
• Harvest Window: Wait for finished flowers and mature trichomes. Watch for cutting too early or pushing too long.
