Remove or partition male plants based on your needs with this quick and reliable technology, saving up to 20% in operational costs.

There are leaf tests that can be performed on plants as soon as the plant has three sets of leaves that can definitively determine the gender of a cannabis plant! These tests are relatively cheap at $10-20 per test, but the information is invaluable to breeders. Some pre-flowers are difficult to find on the plant, or may be hard to determine, which makes a chemical test more definitive than a visual inspection for some plants.

There are also tests that take leaf samples and estimate the overall THC and CBD ratios to expect at harvest! These are a little more expensive at $30-80 per test, depending on exactly what you want to test. Knowing what cannabinoid ratios to expect while plants are still seedlings is very helpful for anyone looking for a very high-CBD or high-THC cultivar!

For those of us who will be determining gender with our eyes, you need to know where to look!

A chemical leaf test can determine the gender and future potency of cannabis seedlings as young as these!

You can learn the gender and estimate the potency of a young cannabis seedling simply by doing a test on a small piece of a leaf

If you still have questions, contact us prior to collecting your samples. We’re here to help you to properly collect samples for analysis.

We just finished a seed crop of 500 phenotypes of 10 different strains. Not having to spend time and effort searching for males was a big saver of production space, labor, and bottom line: money.

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.
