Test was great. Clear instructions, and liked getting to bang the leaves with a hammer. More expensive than I wished, as I would’ve tested more. But good quality and well thought out packaging and method.Matthew B.
Great service, great responsiveness. We have been working with LeafWorks for gender testing for several years and have great confidence in Eleanor and her team.Robinson

Save up to 8 weeks and reduce operational costs by up to 20% with the LeafWorks® Cannabis & Hemp DNA Sex Test. You can identify male cannabis & hemp plants as early as 7 days post germination.
The LeafWorks® Cannabis & Hemp DNA Sex Test is 99% accurate and because we use more biomarkers than the competition, we greatly reduce false positive test results allowing you to confidently remove male plants quickly.
Big news! We have transitioned out of DNA Collection Card submission into a simpler envelope submission format.
In our new submission system, order 1 test per plant.

Simple and Easy
This is my 10th DNA test, this takes all the worry and concern of having a male plant. So far they have been correct 100% . Very fast at results in 3 days maby 4 on a long wait. Also after you use once the next time you get faster serve.
Fantastic! Always getting a quick response to questions. Mainly the quick response with results. Being a medical marijuana patient and not being able to afford it, your service has been critical. Thank you
Really fast and easy! Results came in faster than expected!
Loved the box … wish I could have tracked it back to you.
