How to Grow Critical Mass Feminized Seeds
Critical Mass Feminized Cannabis Seeds are exceptionally easy to cultivate, making them perfect for beginners and commercial operations alike. These plants develop thick, dense flowers that may require support during late flowering due to their weight. With proper care, growers can expect huge yields and resin-packed buds.
Indoor Cultivation
- Flowering Time: 8–9 weeks
- Height: 80–140 cm
- Yield: 600–750 g/m²

- Best Techniques: SOG, SCROG for maximum output
Indoors, Critical Mass thrives in controlled temperatures (22–26°C) and moderate humidity (45–50% during flowering). The strain grows vigorously with a dominant central cola and multiple side branches. Due to the heavy bud formation, branch support is recommended in the final weeks.
