Growing Critical Mass Seeds
Critical Mass is considered an easy cultivar that performs exceptionally well in both indoor and outdoor environments. Its vigorous growth and forgiving nature make it suitable for growers of all experience levels.
Plants generally reach 3–4 feet indoors while producing sturdy branches capable of supporting heavy flowers. Because mature buds can become exceptionally dense, maintaining good airflow and branch support during late flowering is highly recommended.
Indoor growers typically achieve excellent results by maintaining temperatures between 21°C and 26°C (70–79°F) with moderate humidity and consistent ventilation throughout flowering.
Outdoors, Critical Mass thrives in warm climates with fertile soil, balanced nutrition, and regular irrigation. Supporting larger colas during bloom can help prevent branch stress and maximize final harvest quality.
Flowering Time, Height, and Yield Potential
Critical Mass typically completes flowering in approximately 7–8 weeks indoors, while outdoor harvests are generally ready during early autumn depending on regional climate.
Plants usually reach around 3–4 feet in height while producing approximately 400 g/m² indoors and up to 400 grams per plant outdoors under favorable cultivation conditions.
Final harvest size depends on lighting intensity, nutrition, environmental conditions, training methods, phenotype selection, and overall cultivation practices.
