seeds from scratch for the first time can be a daunting task. It requires a lot of research, patience, and the ability to follow instructions thoroughly. To harvest the perfect marijuana plant, you will first need to successfully germinate the seeds. If you have decided to germinate your marijuana seeds, this article is the perfect guide for you. The process of sprouting your first seed can be exhilarating, rewarding, and definitely worth the wait. This article will explain how to germinate marijuana seeds in the best way possible, what is required for the process, and other related details.

Criteria for Germination

Many factors contribute to successful germination. Some essential aspects include cannabis seeds, temperature, warmth, moisture, and darkness.

Cannabis Seeds

Thoroughly inspecting the seeds you can get here with a discount and are about to implant is a wise man’s decision and the first step to ensuring a healthy plant. Good quality seeds will become healthier plants, and poor quality seeds will deteriorate later in their life.

One of the ways to find which cannabis seeds stand a better chance at survival, inspect the color of the seeds. Cannabis seeds that appear darker are more likely to germinate than seeds that are whitish or pale green in color.

Germination Temperature

One of the most crucial factors to consider in a cannabis seed’s environment is the temperature. Germination occurs at specific temperatures, and any fluctuations in these set temperatures can fail to germinate properly.

The ideal germination temperature for marijuana seeds is 22° and 25 °C (71–77 °F). As long as the temperature remains in the set values, seeds will be able to seek out the smallest amounts of moisture. Temperature acts as an indication to take up moisture.

Environmental Factors

Among other environmental factors, you need to consider moisture, humidity, lighting, and pH. Let’s discuss the specifics of all the factors involved in the germination of cannabis seeds and why they are crucial.

The growing environment around the marijuana seeds should be damp or moist but never wet. Too much water can cause the seeds to swell unnecessarily and may cause more good than harm. However, a certain amount of moisture is vital for the survival of the seeds.

The relative humidity range should be between 70% and 90%. 

Another essential requirement for proper germination is that the seeds are placed in a dark place or with fluorescent lighting. The ideal pH of the soil around the seeds should be 5.8 to 6.2.

One last thing that you should remember about marijuana seeds is that try not to meddle with them once you have built the perfect environment and let them grow in peace.

How to Germinate Cannabis Seeds?

Now, before discussing the steps of germinating marijuana seeds, you need to gather all the supplies you would need for the process. The list includes:

  • cannabis seeds;
  • plastic container with a lid or two plates;
  • paper towels;
  • water sprayer with clean water;
  • small cup or glass of water.

Paper Towel Germination Method

Step # 01

Put seed on a paper towel inside a container and spray with room temperature water.

Make sure that you maintain an ideal environment inside the container with perfect humidity, darkness, and warmth at all times. After moisturizing the paper towel with warm water, keep it in a warm place and leave it there.

Step # 02

Open the container at a few hours intervals and keep spraying with water until the seed opens.

If the paper towel dries up, your seed will not be able to germinate and sprout, so make sure there is adequate moisture available inside the container. However, at the same time, ensure that the paper towel is not soaking wet.

Step # 03

Once the seed opens up and the tap root appears, plant the seed in a small cup or plug.

As soon as the seed opens, it is time to transfer the seed to another growing medium such as soil, peat, or cocoa in a small cup or plug for the purpose of sprouting the seeds. 

Autoflowering Cannabis Seeds

For beginners, the most popular method of growing marijuana from scratch is autoflowering cannabis seeds. This method is easier because it doesn’t require keeping track of how much light the seeds receive to germinate.

Usually, cannabis seeds flower when they receive a reduced amount of light daily, typically in the autumn season. However, that bounds growers to wait for the light cycles and can be a hassle.

To solve this, one kind of Cannabis plant called Cannabis ruderalis is planted, which does not require sunlight and autoflowers regardless of the amount of light it receives. 


Germinating marijuana seeds is relatively simple if you follow through with instructions in the guide, but doing it for the first time can be stressful. The most common mistake beginners make in the process is to disbalance the factors required for the seed to sprout. 

As long as you maintain the humidity, temperature, moisture, and light around the seed, your marijuana seeds will sprout in around 4 to 48 hours.
