Cotyledon

« Back to Glossary Index

Cotyledon also known as Seed leaves are the first leaves that appear on a Cannabis Plant. When a marijuana seed breaks the coat open, cotyledon sprout which plays an important role in providing the seedling with the nutrients and energy it needs to begin the growing process. Cotyledon leaves do not look like regular cannabis leaves and later in the Vegetative State, most Cotyledon leaves serve their purpose and naturally fall off.
