PLANT SEX TEST
Identify male and female plants 7-10 days after germination.
Save time, money, and grow space
Get rid of the guesswork
Save time, money and grow space.
Old school sexing methods vary, from force-flowering cuttings in a separate room to waiting up to 3 months to visually identify male attributes. But thanks to science, a DNA sample is all we need to identify the Y chromosome in your plants. Our sex test identifies males and females only 7-10 days after germination—meaning no more wasted time, money and grow space on plants you’re going to throw away.
Results sent to your inbox in 48 hours.
Get results online 48 hours after our lab receives your samples. When you create a Phylos account, you can add shipment notifications, track the status of your orders, and access all of your results in one place. You’ll automatically receive an email notification with a link to your results as soon as your order’s complete.
Just correct results.
We have completed over 10,000 sex tests without a single false call. This is because our scientists have implemented multi-step cross checks to ensure every stage of the testing process meets our rigorous protocol.
We extract DNA from your samples and use a technique called real-time polymerase chain reaction (qPCR) to identify the Y chromosome—because just like in humans, only male plants have a Y chromosome.
Super convenient — and completely legal
Order sample collection kits online and send samples directly to our lab–without ever leaving your grow. The Phylos Plant Sex Test was carefully designed to ensure your submission follows federal law when mailed from legal states via USPS, UPS and FedEX.
“If time is money, Phylos Bioscience’s Sex Test is priceless. The ability to cull males in a matter of days not months is a game changer to say the least!”
– Jerry Whiting, Owner
“We’ve used the Phylos Sex Test on a number of our seedlings with impressive results. Phylos is prompt, professional and 100% accurate. Our grow is fairly small, so we can’t afford to flower a plant if we’re not certain that it’s female. Thanks to Phylos, we’ve been able to crack many more seeds than we would have otherwise, giving us access to significantly broader genetic diversity.”
– Matt Walstatter, Owner/CEO
“These tests were big savers of space, time, and, bottom line: money. They made starting from regular seed much easier than I previously thought. You can have your seeds sexed before transplanting out of your seed starter tray, eliminating the need to transplant all of your germinated seeds. This also saves on production space, media and human resources by not having to spend time and effort searching for your males. We just finished a seed crop of 500 phenotypes of 10 different strains and it appears we have a 100% seedless harvest.”
