Early Detection Saves Grows

The youPCR® Plant Screening Platform allows hemp and cannabis cultivators to screen plants for genetic traits and pathogens, while they are still in the seedling tray. Early screening can be used to prevent costly infestations and save valuable time and resources that would otherwise be spent on plants with undesirable traits, such as males.


Identify and Eliminate Male Plants

Virtually eliminate time and resources transplanting, watering, and monitoring male plants that will never produce flowers. With the youPCR® Gender Detection test, you can identify and eliminate male plants just one week after germination, giving you more time to care for your productive females and optimize your operation.

Identify Cannabinoid Ratios

Get early feedback on your efforts to breed strains with specific cannabinoid ratios. The youPCR® CBDA Marker and youPCR® THCA Marker tests can determine if a plant has the genes needed to produce CBDA and/or THCA, just one week after germination. This will help you better select plants with desirable traits that will be used in subsequent crosses.

Protect Your Grow from Pathogens and Pests

The youPCR® Platform can identify plants infected with powdery mildew, russet mites, or botrytis before they show visual symptoms. Use youPCR® to screen your incoming clones to make sure you are not introducing infected plants to your grow, and continue to screen plants throughout their life so you can keep pathogens in check.

Savings Across Your Entire Operation

The youPCR® Plant Screening Platform allows growers to run a more efficient operation by spending fewer resources on plants that don’t have desirable traits or could potentially unleash a costly infestation.

Cut Electricity Bill

Eliminate males before they use up valuable lighting and HVAC resources that could be better spent on productive females.

Lower Irrigation Cost

Stop wasting valuable water and nutrients on plants that do not have the gender or dominant cannabinoid you are looking for.

Maximize Square Footage

Early removal of plants that do not have the gender or dominant cannabinoid you are looking frees up more space that you can fill with the plants you want.

Curtail Labor

Spend less time inspecting plants for visual signs of contamination or gender, and spend more controlling the environment and taking good notes.

Hear From Our Customers

  • The youPCR platform helped segregate males and F1s in drug-type x industrial hemp crosses. Being able to segregate plants at the seedling stage saves tremendous time, money, and resources. In addition, it helps manage licenses with limited plant counts. Prior to youPCR, everything was done using the observation method. The youPCR protocol is very easy and runs like a charm on any PCR machine with very minimal molecular laboratory skills or training.

  • Working in the cannabis industry in Colorado is extremely competitive and rapidly changing. With new advancements and opportunities at every corner, we have to prioritize efficiency in our breeding program to keep up with a growing market. Conventional breeding methods take a lot of time, labor, and off-site lab testing that slows down our breeding process and costs a lot of money! Working with the Medicinal Genomics team and their youPCR system has given us the opportunity to collect imperative data about our plants in a short amount of time. With the ability to accurately detect plant gender and CBD presence from our seedlings, our selection process has become much easier. YouPCR is easy to use, and our results have been 100% accurate. We would highly recommend getting in touch with the Medicinal Genomics team and seeing what they can do for your garden.

  • From a cultivation standpoint, Early Gender Detection is an awesome tool for us to have in our arsenal. The ability to know which plants are females about 10 days after germinating a pack of seeds saves us time and money. No more wasting precious resources and even more precious space growing out "useless" males.

Same-Day Results You Can See with Your Own Eyes


1. Collect 4mm punches from each plant leaf and place each in one well of the pre-aliquoted Solution A strip tube.


2. Heat the tubes, with either a thermal cycler or miniPCR machine, for 50 minutes.

3. Remove liquid from each well and pipette into a new plate or strip tube, containing youPCR® Solution B and Solution C.


4. Heat the new plate or strip tube for another 40 minutes.


5. See the results! Positive results will change to yellow, while negatives will remain pink.

Flexible and Scalable

All current and future youPCR® tests can be run on either a 16-well miniPCR thermal cycler or a standard 96-well thermal cycler. Customers should consider volume when choosing which solution will work in their instance. The miniPCR platform is best for small grows or home grows, while larger commercial grows will typically be better suited for a 96-well thermocycler. Contact a Medicinal Genomics representative who can help determine the right solution for your situation.


MiniPCR Thermal Cycler

Best for Small Grows

Test 14 Samples Per Instrument Run

Contact Medicinal Genomics to acquire a discount coupon code that can be used when purchasing from the miniPCR website.


Standard Thermal Cycler

Best for Medium to Large Grows

Test 94 Samples Per Instrument Run

Any programmable 96-well thermocycler with a heated lid will work. qPCR detection is not required.

Getting Started with youPCR® is as easy as 1, 2, 3.

Frequently Asked Questions

Can I use youPCR® to test seeds?

No. Although we have done some initial research into using youPCR® to test seeds, we have not done enough to confidently say it works as well as testing leaf. We recommend sampling a seedling’s first set of true leaves when using youPCR®.

Can I use youPCR® to determine cannabinoid percentages?

youPCR® assays provide a positive/negative result. When using youPCR® to screen for CBDA or THCA synthase, a positive result means there is an active CBDA or THCA synthase allele. Unfortunately, that result can’t be used to predict what percentage the plant will ultimately produce. However, if you combine the CBDA and THCA tests you can determine the plant type.

  • Type I Plant (THCA-dominant) = THCA(+) CBDA(-)
  • Type II Plant (THCA:CBDA hybrid) = THCA(+) CBDA (+)
  • Type III Plant (CBDA-dominant) = THCA(-) CBDA(+)
  • Type IV Plant (CBGA-dominant) = THCA(-) CBDA(-)
Does a negative result on the youPCR® THCA Synthase Assay mean my plant will produce less than .3% THC?

No. Plants that test negative for THCA or CBDA may still produce low percentages (<2%) of either compound.

Can I use the youPCR® Gender Assay to detect hermaphrodites?

No. Cannabis plants typically hermie as a response to stress. Although there may be genetic markers that determine if a plant is more likely to hermie, we have not found them, and we do not target them with our gender test. The youPCR® Gender Assay specifically looks for a Y chromosome.

Are all the necessary consumables and equipment included in the youPCR® starter kits?

The youPCR® Starter Kits do not include PCR Thermal Cyclers. We recommend the following models:

  • miniPCR. Use Promo Code “MGC” to receive a discount off list price.

The youPCR® Starter Kits also do not include chemical reagents: Solution A, Solution B, Solution C, and Positive Control. Those must be purchased separately on the Medicinal Genomics web store.

What basic laboratory experience do I need to run youPCR® tests?

In order to successfully test with youPCR®, you should have experience with the following laboratory techniques/best practices:

  • Liquid handling with a pipette
  • Benchtop sterility techniques
  • Proper disposal of tips, punches, strip tubes
Are Medicinal Genomics products ISO certified?

All of the chemicals and reagents we sell in our webstore are manufactured in facilities that are certified to ISO 9001 and/or ISO 13485 standards.
