Origin of Critical Mass CBD Strain
Critical Mass CBD Strain (CMCBD) was birthed by crossing the Afghani strain and Skunk #1 strain. The resulting plant is indica-heavy, containing only around 9% CBD and 6% THC. Critical Mass CBD, therefore, produces an intense calming effect rather than a potent, energetic high.
Growing Critical Mass CBD Seeds
The CMCBD plant is known for its dense foliage that can even break its branches if not well-tended. However, it is easy to grow in confined spaces and can thrive both indoors and outdoors.
Our Critical Mass seeds should be soaked in water in the dark for 3 days until they germinate before being placed in fertilized soil. Autoflower seeds can give multiple yields every 2 months, and feminized seeds will give a yield in under 5 months.
What Climate Does this Strain Grow Best In?
Critical Mass CBD is pretty resilient but does not like extreme climates. We suggest a Mediterranean climate with 35% RH humidity temperatures between 65F to 80F. If you grow it outdoors, keep the plant dry and protected from frost. If indoors, keep a close eye on the thermostat to prevent mold from growing.

Feeding Critical Mass CBD
As with other strains, proper feeding is key to getting good yields with CMCBD. Adding the right fertilizer in the correct amounts at each stage will prevent nutrient burn. Critical Mass CBD is resistant to pests and diseases so you should not worry too much about these.
Flowering & Yield
Critical Mass CBD grows well both indoors and outdoors. The plant takes around 2 months to start flowering, growing numerous resinous buds. You should expect to harvest less than 60 days after flowering. When grown indoors, you can expect around 600g of harvest per square meter, and around 700g or more per plant if grown outdoors.

Experiencing Critical Mass CBD Strain
Critical Mass CBD is known for its CBD calming effects, reducing muscle tension and nausea that comes with migraines, tension headaches, and chemotherapy. CMCBD is not psychoactive and is great to use when you want to rest after a long day or get some sleep if you suffer from insomnia.
Critical Mass CBD Taste & Smell
This strain is known for its sweet scents reminiscent of just rained-on trees in the forest. When you smoke it, expect an explosion of flavors like honey, lemon, and fruits.
