We extract DNA from your sample collection cards and use qPCR analysis to identify the Y chromosome. All hemp plants have an XX or XY combination, indicating a female or male plant at a genetic level.

There are a number of reasons. 1) Taking a sample from a cotyledon leaf is the fastest way to identify the gender of your seedlings. 2) There is no THC in cotyledon leaves making samples legal to send in the mail. Our tests were designed to be in compliance with the Controlled Substances Act.

Each country has different laws and regulations about buying products from other countries. Before you place your order, please be sure of your local customs laws concerning the shipment. It is your responsibility to know what is legal in your country and what is not.



***If your cotyledon leaves are wilting or have already fallen off, please call us.
