Relish in the potent fusion of two legendary strains with Auto Critical Mass Auto-flower seeds. Renowned for its easy cultivation, high yield, sweet flavors, and impressive THC content, this strain is an automatic version of the famed Critical Mass. Bred meticulously by Advanced Seeds, this variant maintains the coveted potency and fruity terpenes that made the original strain popular while reducing the flowering period.

Auto Critical Mass Auto-flower seeds are derived from a harmonious blend of Critical Mass and Ruderalis Skunk genetics. With a growth cycle of approximately 70 days, this strain can reach heights of 90cm indoors and up to 2-3 feet outdoors. Providing a minimum of 5-6 hours of direct sunlight outdoors is recommended for optimal development.

This incredibly productive auto-flowering variety boasts delightfully sweet and fruity aromas, complemented by a powerful effect due to a THC level of up to 16%. The notable potency and tantalizing flavor profile make Auto Critical Mass a standout auto-flowering version of the acclaimed Critical Mass strain.

This 2nd Generation of auto-flowering strain exhibits a higher uniformity among individuals, a faster flowering period, and increased production of resinous buds. The elevated CBD levels also make it a viable option for medicinal use.

Exhibiting superior adaptability, Auto Critical Mass is resistant to pests, fungi, drought, and adverse environmental conditions, making it an excellent choice for commercial and experienced growers.

Auto Critical Mass embodies the best of its heritage, featuring a fruity and earthy flavor profile accentuated by sweet hints of berries and wood. The psychoactive impact of this strain is an unforgettable sensory experience, promising a perfect balance of relaxation and euphoria.

Growing Auto Critical Mass:

Auto Critical Mass is an easy-to-grow strain that performs well both indoors and outdoors. Here are some best practices for cultivation:

  1. Light: This strain needs plenty of light to thrive. Indoors, it’s recommended to have a powerful lighting system with an 18/6 light-dark cycle for optimal growth.
  2. Soil and Nutrients: Use high-quality, nutrient-rich soil for optimal plant health. It’s also beneficial to add organic fertilizers or compost to enhance the nutrient content of the soil.
  3. Temperature and Humidity: Auto Critical Mass prefers a warm and dry climate. Indoors, aim for temperatures between 70-85Β°F (20-30Β°C), with humidity levels dropping as the plant matures.
  4. Watering: Water thoroughly but infrequently to encourage root growth and prevent overwatering. Wait until the top inch of soil is dry before watering again.
  5. Pruning: Auto-flowering strains like Auto Critical Mass don’t typically require much pruning due to their short vegetation period, but removing dead leaves and low growth can improve airflow and light penetration.
  6. Harvest: Auto Critical Mass is usually ready for harvest in 70 days from seed, depending on the growing conditions. You can confirm if it’s harvest time by checking the color of the trichomes with a magnifier.

Remember, the specifics can vary depending on your grow setup and the specific phenotype of your plant, so adjust these general guidelines as needed to suit your circumstances.
