Critical 47 Seeds

Genetics & effects

Critical 47 is a feminised photoperiod hybrid combining Critical Mass and AK-47 genetics. Its listed 50% sativa and 50% indica profile may appeal to growers seeking balanced structure and character. Catalogue figures place THC at 18% and CBD at 0.2%, though final expression can vary with phenotype, environment and cultivation technique.

The aroma and flavour profile brings together ripe fruit, tangy lemon and a distinctive cheesy note. Limonene, myrcene and caryophyllene are the listed dominant terpenes, creating a layered impression that may shift from bright citrus to earthy spice. Experiences are subjective, but some people describe the effects as initially euphoric before becoming relaxed and sleepy. Individual impressions can differ considerably.

Growing in Australia

Critical 47 is listed as an intermediate-level variety suited to temperate and hot, dry climates. Its vigorous growth and potentially heavy flowers call for attentive canopy management, airflow and branch support. For outdoor photoperiod cultivation in the southern hemisphere, spring planting generally falls between September and November, with local conditions guiding the exact timing.

Monitor humidity closely as flowers gain density. Good spacing, selective pruning and steady air movement can reduce the risk of mould. Avoid abrupt changes in watering or nutrition, and allow the growing medium to dry appropriately between irrigations. Its balanced heritage can produce multiple phenotypes, so height, aroma, flowering pace and colour may vary.

Indoor

Indoors, plants are listed to reach up to 120 cm and may produce up to 550 g/m² under suitable conditions. These figures are potential outcomes rather than promises. A flowering period of approximately 10–12 weeks is listed.

• Use training and pruning to maintain an even, open canopy.
• Provide support before flowers become heavy.
• Keep air moving above and below the canopy.
• Check temperature and humidity regularly through late flowering.

The moderate indoor height can suit a range of spaces, but the long flowering window rewards planning. Growers may notice stronger cheese, fruit and lemon aromas as flowers mature, making ventilation and odour management useful considerations.

Outdoor

Outdoors, Critical 47 is listed to grow up to 180 cm and yield up to 700 g per plant in favourable settings. Choose a sunny position with free-draining soil and room for lateral growth. In hot, dry areas, mulch can help moderate root-zone moisture, while morning irrigation may limit prolonged surface dampness overnight.

Temperate growers should consider autumn rain and humidity when selecting a position. Shelter from severe wind, sturdy branch support and an uncluttered centre can help plants carry substantial flowers. Regular observation is especially valuable as seasonal conditions change.

Harvest

Australian outdoor harvest commonly falls between March and May, depending on latitude, spring planting date, phenotype and weather. Assess flower maturity directly rather than relying on a calendar alone. Indoor harvest generally follows the listed 10–12-week flowering period. Careful handling, gradual drying and clean storage help preserve the variety’s fruit, lemon and cheese character.
