I want to start this topic to discuss different methods for sexing Cannabis Plants. There’s a company called Phylos Bioscience that does plant sexing, and requires a sample from the Cotyledon leaf. You take the leaf and mash it between a paper test card then mail it for testing. Results are quick and available within days on their website when you log into your account.
Does anyone else know of any other companies or methods to determine plant sex prior to maturation?
