LeafWorks Gender ID Test Kits identify the gender of each seedling in the first seven days after germination.

This DNA-based service identifies male Cannabis/Hemp plants as early as seven days post germination. With more markers than other comparable tests, the LeafWorks Gender ID Test is 99% accurate. Remove or partition male plants based on your needs with this quick and reliable technology, saving up to 20% in operational costs. You can save yourself 6-8 weeks of time, energy, and resources waiting to sex plants by eye.  

Each Gender ID Test allows you to identify the sex of four separate plants.

Bulk pricing is available*


Submission is easy and legal for mailing.

You will need to send in all four kits at one time.  The cost of the tests covers a once time submission.  If you only have 1, 2 or 3 plants you want to check then simply send in those samples and you will get your corresponding results returned.  You can also send in multiple samples of the same plants if you like.  If any of the tests are not sent in they are not usable in the future and a separate set will need to be ordered.

Test results will be emailed to you within 3 - 7 business days of the lab receiving your samples depending on the volume of cards to be processed.

The Future of Cannabis

I absolutely loved every aspect of the Leafworks Gender ID Test. It was easy to use and we got the results way sooner than expected. Whether you're a breeder or just want to grow from regular seed stock, this test kit is essential. Gender ID testing is the future of cannabis cultivation, and I absolutely plan on purchasing the Leafworks ID Test again for future grows.

Not 100% guaranteed!!

Using the kit was easy enough, but 2 plants ended up being males that they said were females!!! Check your plants if you use this method!!! It could cost someone a harvest!!!
