Description

Autoflowering Version Introduction

The eagerly anticipated autoflowering form of the flagship strain, Monster Mass, by Critical Mass Collective, is well-adapted for both indoor and outdoor environments. It features three main phenotypes: neon green, slight purple, and the preferred “eerie blue,” which produces ghostly blue flowers with a sweeter, fuller floral scent and taste. All phenotypes offer the same THC levels as their photoperiod mother and grow to heights of 60-140cm. Despite their variation, each phenotype is equally productive, with branches bending under the weight of dense buds by harvest. Employing a SCROG technique can enhance yield and bud site production. Harvest is generally around 70-80 days, when buds are dense and dripping with trichomes.

Key Genetics

Genetic makeup combines Monster Mass with CMC Big Bud Auto, ensuring robust growth and significant resin production.

  • Sex: Feminized.
  • Outdoor yield: Approx 200-300g/per plant
  • Indoor yield: Approx 800g/m2
  • Seed to flower: Approx 70-80 days
  • Height: Approx 60-140cm
