A visual examination is the first step in determining the potential viability of a cannabis seed. Look for seeds that have a dark, healthy coloration, as pale or light-colored seeds may indicate immaturity or poor health. Viable seeds often exhibit a mottled appearance, with a sturdy outer shell that is smooth, shiny and intact.
Size and Shape:
Another important characteristic to assess is the size and shape of the seed. Larger seeds generally have a higher chance of viability compared to smaller ones. Additionally, viable cannabis seeds are usually teardrop-shaped or slightly oval, indicating healthy development.
Hardness Test:
The next step involves performing a hardness test to evaluate the seed’s integrity. Gently squeeze the seed between your fingers. If it feels firm and does not crack or crumble under pressure, it is likely viable. Conversely, a soft or brittle seed may indicate poor viability or age.
Float Test:
The float test is a simple yet effective method to determine if a cannabis seed can germinate. Fill a glass with water and carefully drop the seed into it. Viable seeds will sink to the bottom, while non-viable ones will float or remain suspended in the water. Floating seeds are typically empty or have not developed enough to be viable.
