CBD Critical Mass Auto Seeds

Genetics & effects

CBD Critical Mass Auto combines CBD Critical Mass lineage with an autoflowering, Cannabis ruderalis-derived line. The result is a feminised autoflower with an approximate 80% indica and 20% sativa profile. Kiwi Seed Bank presents it as an approachable option for growers who favour compact timelines and plants that flower according to age rather than changing daylight hours.

Reported cannabinoid ranges are approximately 3–5% CBD and 3–5% THC. Individual experiences remain subjective, but the effects may feel relaxed and happy while retaining an uplifting or lightly energetic edge. Aroma and flavour can combine citrus and lemon with sweet, earthy, woody and spicy notes, followed by pungent skunk accents. Myrcene, limonene and beta-caryophyllene are among the associated terpenes, although expression can vary between plants and growing environments.

Growing in the named country

For New Zealand’s southern-hemisphere calendar, spring planting falls between September and November. This autoflower can suit hot, dry regions, temperate areas and cooler locations with shorter summers. Select a bright position, shelter plants from severe wind and avoid consistently saturated soil. In humid districts, generous spacing and steady airflow may reduce the risk of mould around dense flowers.

Autoflowers move through growth quickly, so early stress can have a lasting influence on size. A light, free-draining medium, stable conditions and restrained feeding are generally preferable to frequent major changes. Before possessing or growing cannabis seeds or plants, check the current rules that apply in New Zealand and your local area.

Indoor

Indoors, plants may reach up to 140 cm, depending on container size, lighting, environment and plant variation. A consistent light schedule simplifies the setup because flowering does not rely on a seasonal switch. Gentle plant shaping early in vegetative growth may help keep the canopy even, but heavy pruning is less suited to the limited recovery time of an autoflower.

Keep air moving above and below the canopy, and monitor moisture near developing flowers. The listed indoor yield is up to 600 g/m² under favourable conditions. This figure is an indication rather than an assured outcome, with experience, equipment and phenotype all influencing performance.

Outdoor

Outdoors, the listed height is up to 120 cm, making this a comparatively manageable choice for sunny patios, greenhouses or garden spaces where permitted. Use a container or bed with reliable drainage and allow the upper layer of the medium to dry moderately between watering. In exposed areas, discreet support can help branches remain steady as flowers gain weight.

Potential outdoor production is listed at up to 120 g per plant. Strong sunlight and stable warmth may support fuller development, while cool nights, persistent rain and limited direct light can lower output. Aromas may become pungent late in flowering, with citrus, wood and skunk among the more noticeable notes.

Harvest

The stated flowering period is approximately 7–8 weeks, though the complete seed-to-harvest cycle may be longer and should be judged plant by plant. For New Zealand planning, spring sowing takes place from September–November, while the main outdoor harvest window is March–May. Autoflower timing can finish outside that window depending on sowing date and local conditions.

Assess maturity through overall flower development and trichome appearance rather than relying only on a calendar. Harvest during a dry spell where possible, handle flowers carefully and maintain clean tools and good airflow during post-harvest drying to preserve their colour, aroma and structure.
