About Germinating Marijuana

The first step in growing your own cannabis is often one of the most intimidating. Is it possible that a 4 foot tall, thick trunked and heavily budded marijuana plant can burst out of that insignificant little seed? Waiting for the first leaves to sprout can be an agonizing experience. If you understand how seeds germinate and what you can do to increase their odds of producing healthy plants, the whole process becomes easier.Just Sprouted Marijuana Seed

The Process…

  • 1. Choose the right seeds

If you purchased your seeds from a seedbank, you’re going to plant them all. But if you are using seeds from a bag of bud or from your own breeding program, you have some degree of choice.

White or green seeds are immature and will probably not sprout. Mature seeds have a waxy, shiny shell and come in varying shades of brown. You may even have mottled seeds that resemble a turtle shell.

  • 2. Soak your seeds.

Getting your seeds thoroughly wet before planting will help speed up germination. You can either soak them in a small amount of water (mineral water is best) overnight, or wrap them in a damp paper towel.

  • 3. Two ways to Germinate
    • a. If you soaked your seeds in water overnight, you can now place them in your growing medium, carefully covered with 3/16” of medium. Keep the medium evenly damp but not soaking wet.
    • b. You can also germinate the seeds right in the damp paper towel. Keep it in a dark, warm place and keep it wet until the seeds crack. When the root is ¼”- ½” long, CAREFULLY transplant it into your growing medium.
  • 4. Be patient.

It will take about a month for your strongest seedlings to become fully rooted and ready for transplant into a larger container. Don’t rush them. If the root system is not well developed the stress of transplanting can damage your young seedlings.

Choosing a Growing Medium

Germination Station Labeled RockwoolSeeds can be germinated in a wide variety of mediums. Remember, the seed has all the stored nutrients it needs to get started. You do not need to give it any nutrients, just plain old water, for the first week or so. Whichever growing medium you choose, make sure it holds water well. Here are our favorite options:
  • 1. Soil
  • A high quality potting soil that holds moisture well is great for germinating cannabis.
  • 2. Soilless potting mix
  • These mixes usually include coco coir, perlite, vermiculite, peat or a combination of these four.
  • 3. Rockwool Cubes
  • Made from spun out melted rock or metal these cubes hold water well and work great for germination. Once your seedlings are started you can move the entire cube into a hydroponic system.
We don’t recommend Hydroton or other expanded clay pellets or any form of gravel as these mediums do not retain enough moisture for good germination.

Keeping the Right Conditions for Germination

First True Leaves Cannabis SeedlingTemperature and moisture are the two essentials for successful marijuana germination. You want to keep the soil temperature between 75° and 80°. Temperatures below this will result in slower germination or poor germination rates, while temps above 90° can damage seedlings.Your growing medium must always be damp, but never soaking wet, throughout the entire first month of your plant’s growth. Many growers water with a spray bottle during this stage to avoid flooding the delicate seedlings.
