Choosing Seeds

Feminized seeds flower and grow weed when they receive less than 12 hours of light per day. Harvest outdoors in fall, or indoors after 15-20 weeks. Professional growers use these.

Autoflower seeds grow small, easy-growing plants that you can harvest in 10 weeks. Great for new growers, small spaces, or multiple harvests per season!

How To Germinate

Germination is guaranteed when you soak the seeds in water up to 72 hours in darkness. When it shows a tail, put it in loose soil with fertilizer. Keep it light and damp and a seedling will appear!

Critical Mass cannabis seeds are easy to grow. These feminized autoflowering seeds produce an automatically -flowering cannabis hybrid and are the result of a combination of Critical Mass with a hearty ruderalis cultivar. Auto Critical Mass has moderate CBD content and high THC content that can exceed 20%. Large buds and a fast harvest make this a favorite for many growers.

Critical Mass Autoflower Origins

Auto Critical Mass is a second-generation auto-flowering strain that combines popular indica varieties. The regular version is a fast-flower blend of Afghani and Skunk #1 strains. Afghani strain belongs to the Indica family, and Skunk #1 is particularly known for its potency and strength.  

Critical Mass plants tend to grow lots of resinous buds, depending on how long it remains in a vegetative state. However, because it is auto flowering, Critical Mass veg time is not a variable. It will automatically flower after a set amount of time.

What Is Critical Mass Autoflower?

In the 80s, weed breeders discovered Cannabis ruderalis, a variety of cannabis closely related to Cannabis indica and Cannabis sativa. Ruderalis stands out for its speed of growth, as it can flower in weeks and be harvested multiple times in a season. This reliable grow time prompted cultivators to start mixing ruderalis genes with Sativa and Indica strains, creating a new type of autoflowering strain.

Autoflowering Critical Mass is a balanced hybrid of Critical Mass, also known as Big Bud. Autoflowering hybrids like Critical Mass auto grow rapidly. They also can be harvested much quicker than non-autoflowering options. Since they are smaller than conventional marijuana plants, they are ideal for both indoor and outdoor growers. New growers appreciate these feminized seeds because they are guaranteed to flower and they always know when to harvest Critical Mass, even if they haven’t practiced growing marijuana.

Growing Critical Mass Autoflower Seeds

In general, these marijuana plants are easy to grow (especially when grown from feminized seeds) and produce a high-quality, high THC buds regardless of how they are cared for. The popular automatic version stays small, with most plants staying under 3 feet (80-90cm) when mature. As it grows, it develops a long central bud covered with orange hairs. During the flowering stage, this cannabis plant produces sticky resin-coated buds within 8 weeks when grown indoors.  

Critical Mass tends to be a high-yielding strain with big resin-filled and snowy-white buds that give a strong aroma. In its growing phase, this plant reaches a 'critical mass', which sometimes causing its branches to break away from its thick bud. However, most Critical Mass auto grow journal entries reveal that the autoflowering version is a lot easier to maintain.   

The best way to grow Critical Mass Auto cannabis seeds indoors is with the SoG (sea of green) method. This growing technique helps improve airflow, which is important because its compact nature can lead to bud rot. For the strongest effects and highest yield, outdoor growers can cultivate it outside from May to August. For better root and overall plant growth, consider improving the soil aeration by adding 30% coco.

Preferred Climate

While Indica dominant hybrids flourish in dry regions, Sativa dominant hybrids thrive in warm subtropical climates. This Indica-dominant hybrid prefers temperatures between 68 to 80 degrees Fahrenheit to thrive. When grown outdoors, this plant produces a lesser yield, so growers will need to plant across multiple growing seasons to achieve a large Critical Mass harvest.

Experiencing the Critical Mass Strain

With Critical Mass, you experience a relaxing and long-lasting sensation that is more physical than cerebral.

This cannabis strain is an excellent choice for chilling out in the evening without getting couch lock.

Since this strain can cause you to feel dehydrated, stay hydrated by drinking a lot of fluids.

When you take a hit, you’ll notice citrus and skunky qualities accompanied by the sweet flavor. When you exhale, you will taste the unique sweetness mixed in with earthiness.
