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

    My first adventure with LeafWork

    Took samples and was notified as soon as they received it. In just a few days had my results. Ordered a few more test and are now waiting for the results on them. Will do another review when I’m finished with the next run of test. Thanks Travis A

    One week turn-around

    Samples were sent on a Monday, notified on Thursday the package was received at LeafWorks, and results emailed the following Monday. All 10 results confirmed correct on adult plants. Definitely helpful.
