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 10-14 weeks. Great for new growers, small spaces, and 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!

Growing Critical Mass CBD Autoflower Seeds

If you're looking for a resilient plant, this is it. Its resiliency is one of the reasons this is such a popular strain among growers. Critical Mass plants are known for being consistent and taking very little effort to flourish. They produce critically massive buds in just about any growing conditions.

In addition to already being easy to grow, these seeds are autoflowering! That means they flower automatically without the grower having to recreate the natural light cycle. For those looking to grow the easiest possible version of a very popular strain, this is a great place to start.

Critical Mass CBD Autoflower Plants

Even as autoflowers (which tend to be smaller than other plants) Critical Mass autoflowers buds still retain their famously large size. Sometimes known as Big Bud, these plants produce buds that are 'critically' heavy and huge. So, you may have to put in a little work to support those buds and keep them dry. If your plant starts to sag under the pressure of all that weight, create a little support system until it's time to harvest.

Preferred Climate

Critical Mass prefer a Mediterranean environment but can thrive in any environment.

Critical Mass plants can be quite large and are best suited for outdoors. However, you can easily grow Critical Mass CBD Autoflower seeds indoors because autoflowering plants do not grow as large as traditional varieties. The plants are quite resilient but can die from frost or suffer from mold if not kept dry.
