Critical Mass: A Mass of Resinous Buds for All Climates

Critical Mass is a feminized, Indica-dominant cannabis strain developed by Advanced Seeds as a cross between an Afghani breed and Skunk 1 to yield a hybrid with big, densely packed buds and equally impressive sweet but earthy and woody flavors. Reaching yields as high as 550 – 650 g/m2 with the right cultivation, Critical Mass is a dream for any grower.

With a standard flowering time of 9 – 10 weeks, she isn’t the fastest of growers however, she is worth the wait as the end of flower sees her bearing rock-hard buds packed with resin. Reaching heights of only 100 cm indoors, she’s terrific for growers with limited space and her natural adversity to more challenging climates means she can be grown with heavy yields even in colder regions. In the earlier stages of the grow, a little training goes a long way – techniques such as supercropping can be used in tandem to deliver up to 650 g/m2 of dense, sticky cannabis. Here is some further information to help you grow this strain:

  • Medium height – 90 – 100 cm
  • Max EC of water – 1.4 in veg, up to 1.8 in flower
  • Recommended grow medium: Aeroponics – excellent yields from Critical Mass when grown hydroponically.
  • Recommended nutrients: Nectar for The Gods range

Sweet Yet Woody Flavors

Known for her earthen, woody flavors, Critical manages to combine this with a surprising sweetness. The combination of these flavors along with the balance of mind and body effects, she will leave you with a memorable experience that you will thank your stars for the stupendous yields.
