How Long to Soak Cannabis Seeds

So how long to soak cannabis seeds, and what solution should you soak them in? This is a common question, and one that even when researched online, only adds to the confusion. Let me clear up the confusion as simply as possible.

Before attempting the germination process you may want to soak your cannabis seeds in water, and/or Hydrogen Peroxide. This can be especially important if the marijuana seeds you want to germinate are old, or less viable for any reason. I will delve into both these methods below.

Cannabis seeds can be the most expensive part of growing marijuana. You can buy them online, but they can be more expensive than buying the actual plants themselves…..well except here at JustCannabisSeed.com :). So if you want to start your own grow, it’s best to do so with your own seedlings—which means that you’ll need to germinate your own cannabis/marijuana seeds.

Lets look more closely at the two methods I would recommend….Soaking your cannabis seeds in water, or soaking your cannabis seeds in a hydrogen Peroxide solution….

Soaking Your Cannabis Seeds in Water

Sink or Swim?

Soaking your cannabis seeds in water is one of the best ways to start a new grow.

Generally good, viable cannabis seeds will sink, and immature, or bad seeds float.

This is not etched in stone however.

If the floaters are very pale, and look immature, they probably are. If the floaters are dark, and look mature, I generally plant them, and give them their chance at life.

You can soak your seeds in a variety of solutions, but we recommend using distilled water. This is because it contains no minerals or chemicals that could harm your plants. You should also avoid using tap water or any other type of water that has been treated with chlorine or fluoride.

Soaking cannabis seeds in water is a great way to make sure that your plants get a good start, and it’s also a good way to help prevent the spread of pathogens, that may be on the outside of your seeds. Think of the critters, and molds and mildews the mother plants could have been exposed to.

Soaking your marijuana seeds prior to germination is a good way to prevent low germination rates as well. Might as well give your seeds their best opportunity to experience life…..

Soaking cannabis seeds in water makes it easier for the embryo to split the seed shell as well.

Soaking your cannabis seeds in water is not rocket science. Here are the steps:

  1. Gently wash your seeds with water. This will help remove those possible pathogens we talked about.
  2. Soak the seeds in a container of water for 10-12 hours (or overnight). This is all it should take to give them a good start.
  3. Remove the soaked cannabis seeds from their soak solution and gently rinse them in clean water.
  4. Now you are ready to simply plant them in your chosen growing medium, make sure to water them in a bit so they will retain the moisture you have given them.

Soaking Cannabis Seeds in Hydrogen Peroxide

Soaking your cannabis seeds in Hydrogen Peroxide can be an excellent way to destroy pathogens like the one that can cause damping off.

You may have heard the name “hydrogen peroxide” before, but if you’re not quite sure what it is or how it works, you might be wondering why you should soak your cannabis seeds in Hydrogen Peroxide??

Hydrogen peroxide is an antimicrobial agent that can be used as a disinfectant, and it’s also an excellent way to help germinate cannabis seeds. Hydrogen peroxide is a great alternative to bleach, and it’s cheaper, too. You can buy it at any grocery store or drugstore.

Have you ever wanted to know how to soak your cannabis seeds in hydrogen peroxide? It’s super easy! Here’s how it works:

  1. Fill a bowl or jar with water and add two tablespoons of hydrogen peroxide.
  2. Soak the cannabis seeds for 10 minutes or so (you can do this overnight if you’d like). You’ll notice that the seeds will start to bubble up as they soak up the hydrogen peroxide, which is normal and fine!
  3. When they’re done soaking, rinse them off under cold water and then dry them off with paper towels or a clean cloth towel.
  4. I then like to go ahead an soak them in water as outlined above.
