Why DNA Sex/Gender Testing Is A Game-Changer In Cannabis Cultivation

Delta Leaf does many things well, including offering cannabis growers an innovative method of DNA testing that lets them know whether their plants are male or female months before sex could be determined by traditional methods.

Traditionally, phenotype identification, e.g. sex/gender, has taken place when the plant has grown large enough that you can visually distinguish the different physical characteristics. For sex identification, this would include pollen sacs on male plants or pollen-collecting stigma on the females.


While visual detection of gender has been the general best practice for the industry for years, it typically is impossible until later in a plant’s growth cycle. Most growers know how useful it is to learn a plant’s gender as early as possible, so they won’t have to invest a lot of time and resources into plants that may need to be culled if and when the wrong gender turns up.

If you’re a grower, DNA testing is a smarter and faster method to get you the data you need to better plan and organize your operation.

Some of the benefits of testing include:

  • Saving time. Delta Leaf offers the opportunity to discover if a plant is male months before it could be traditionally detected.
  • Saving resources. Having an accurate count early on of which plants are going to be viable can mean you use less water, less electricity, and fewer nutrients and similar supplies.
  • Saving on labor/payroll. With fewer plants and less need to monitor the gender of every plant all the time, you can hire fewer people or have more of your staff focus on other projects.
  • Maximizing canopy space. By knowing exactly what you’re growing, you can have more control over how many plants are in each room and more efficient use of your square footage. You may even see that plants grow better when they are at the optimal density.
  • Better plant management. If you remove the males right away, you’ll be able to use that additional space to start new plants and keep the grow cycle going. You can transplant once and be done instead of transplanting males, then waiting to sex them before you transplant again.
  • Security and peace of mind. Failing to properly identify male plants can potentially impact your entire operation. This ultimately is one of the hardest advantages to quantify. By removing the risk of male plants early on in the grow cycle, you’ll feel better and have one less worry on your plate later on.
  • The bottom line: it saves money. Sure there is an up-front cost for genetic testing, but it’s less than the equivalent cost of the time, resources and supplies needed to grow a batch of plants that might have to be culled. Testing provides better value, but don’t just take our word for it. You can determine the exact dollar amount you’ll be saving by using our free online calculators to compare the cost of visual detection to the investment in early detection of sex/gender by DNA testing. a better use of your funds and will allow you to cultivate females.

Planning ahead
Using the early detection methods offered by Delta Leaf, you can receive great peace of mind for what you’re growing. By following an easy sample collection process, you can learn the gender of your plants well before you invest a lot of time and energy into growing them.
