Healthy cannabis seeds have aesthetic qualities that can easily be determined when compared to poor quality seeds. A healthy cannabis seed holds a seed that has a dark color with elements of black, brown or grey. Some strains have a tiger-looking seed strain. If the cannabis strain has a greenish or whitish appearance most likely, these seeds are still immature so there is no way for them to sprout. The healthy seed is often hard and it can’t break easily because of a coating wax on their shells.

  • Size and shape

A healthy seed can be identified easily when compared to an immature seed. A healthy seed would have an asymmetrical shape or tear-drop shape. While an immature or poor seed will show small, flat or mishappen seeds.

  • Hardness and durability

A quality cannabis seed has a hard outer shell that has a smooth surface without any cracks or crinkles. a seed that is squishy, pliable or tender should no longer be planted because it would only result poorly.

  • Weight

A heavy seed would lead to higher quality because it contains moisture and nutrients. An unhealthy seed tends to be lighter because it has no capabilities to contain needed moisture and nutrients.

  •  Float Test

The float test is another way to check if the seed is viable or not. You’ll just need to drop the seed into the water. If the seeds will sink within 1 hour, it is an indication that it is a viable seed that has a higher chance of successful germination. 

Signs that the Seeds Is Unhealthy


  • If the seeds fail to germinate

There is a possibility that the reason why your seed failed to germinate is because of too much or too low temperature, the soil dried out or the seeds are improperly stored before use.

  • The seeds decayed when planted

When the seedlings died after planting it there is a possibility that the seed had a disease and there is little chance of reviving it. There is also a possibility that the soil is not sterilized, the container used is not hygienic, the seedlings were improperly spaced and that there is excessive moisture.

  • The leaves of the newly sprouted seeds curl

  • In the germination process, make sure that the paper towel that you will be using will not lose its wetness. You may need to sprinkle it with water from time to time so that the seeds will not lose its moisture.
  • It is best to use a cannabis seed that is already mature, an indication of mature cannabis seed is the tiger stripes indicated on the sides of the seed. Usually, a large-looking seed tends to yield more hardy and vigorous cannabis plant.
  • The cannabis seeds should be kept in a temperature between 75 to 85 degrees Fahrenheit to induce sprouting. You may place it on top of the fridge, near the window sill or in a heating pad. If the right temperature is sustained, you can be sure that you will have the results within 48 hours.
