Cannabis seeds have a firm outer shell to survive adverse conditions for decades in the wild. To encourage proper germination of cannabis seeds, you should scarify first. There are plenty of ways to scarify the cannabis seeds. For thinner-than-usual pods, nicking or rubbing may be enough. For thicker pods, soak them in boiling water for a few hours. You can also use rubbing alcohol or any other strong acid solution.
Scarifying cannabis seeds helps to reduce the hard impermeable outer layer, which doesn’t allow water and nutrients to get through. This is done by mechanical or chemical means, and in both cases, you should do it before sowing the cannabis seeds into a growing medium.
When you’re looking for tips on improving your germination rate, it’s essential to understand how seeds typically sprout. It all begins when the outer shell, or integuments of the cannabis seed, break down as it interacts with moisture. The embryo cells then become turgid and begin to grow, causing the radicle and plumule to emerge into the world!
Many growers get frustrated when their seeds don’t grow. Other problems they may face include seeds that are hard to germinate, slow growth, or death after a few weeks of growth. These problems are almost always due to weak plants that are not prepared for germination and early plant growth rigors. Scarifying cannabis seeds has proven to increase germination rates and help even the most stubborn seeds sprout. Here we’ll show you how to scarify cannabis seeds.
Mechanical scarification, more commonly known as nicking, involves cutting or breaking the outer layers of the seed coat with a sharp tool. Use a thin-bladed knife or other sharp objects. Stay away from anything that would damage the embryo, such as a saw. By removing only a few outer layers of the endocarp (seed coat), you allow water and nutrients to penetrate the embryo to help it sprout.
There are many reasons why cannabis seeds won’t sprout, but a big, most common culprit is the lack of hydration. Once you’ve cleaned and disinfected your weed seeds, they should be ready to soak in some water for roughly 24 hours. But some varieties can benefit from a slightly different approach. For large seeds (i.e. Blue Dream) or ones that tend not to break dormancy quickly, scarifying can help you get a jump-start on germination rates.
Scarifying means to nick, scratch, or mar the surface of the seed to be more permeable. This helps water and oxygen enter the seed and reach the embryo. Without proper scarification, seeds can take weeks, if not months, to sprout.
Cannabis seeds have what some describe as a ‘harsh’ outer shell that makes them hard to crack open. The cover does this for a reason, helping protect it from birds and other animals who may want to eat it. When you’re trying to grow, this hard shell is almost like a blockade between you and your plant baby. Your goal is to scarify your seeds to make them grow faster.
Before their popularity in the last 50 years, many cannabis species were endemic to specific regions throughout the globe.
Many are adapted for water submersion, while others are capable of being digested and remaining intact or to latch onto the fur of a passing animal.
The ways that seeds are dispersed are many, but cannabis has recently found an interesting partner to help in its dispersal. Humans are the leading cause for transporting cannabis seeds throughout the world.

Some seeds are equipped with “wings,” which are adaptations that allow the seed to ride the current of the wind for an extended period of time so that it’s dispersed away from its mother.
Plants have come up with ingenious ways to disperse their seeds, using wind, water, animals, and even though their own physical force to throw them out.
A seed is an embryonic plant. Just as humans are embryos at the earliest stage of life, so are seeds.
