What can I test with the HiGrade app?
HiGrade provides instant plant analytics. Our app helps cultivators and consumers know more about their plants, using artificial intelligence algorithms.
The app has three main features:
1. (Free) Grade - instant general grade assessment for cannabis flowers.
2. (Pro) Potency (%THC) - instant potency analysis for dry flowers from THC-only strains.
3. (Pro) Grower - cultivation assistance, regarding any questions or issues you may encounter during your grow cycle.
To unlock the Pro features, order your HiGrade Kit today. Inside the kit, you'll find the activation code for the app and a Scope required for the %THC and Grower features.
Is the HiGrade app free?
Yes, there is a free version containing the Grade feature. To access the Pro features (%THC and Grower), you’ll need to order the HiGrade Kit.
Where can I order the HiGrade kit?
You can order the HiGrade kit from our website, through the HiGrade app, and from Amazon (USA only). You can also purchase it from selected retailers around the world.
What is included with the HiGrade kit?
The kit includes one HiGrade Pro app activation code (QR) and one HiGrade Scope. The activation code activates the Pro app for one year, allowing you to perform up to 400 analyses per month.
Why should I buy the HiGrade Scope to activate HiGrade Pro?
When you purchase the HiGrade Kit, you are buying both the Scope and the HiGrade Pro activation code. The code unlocks the Pro features (%THC and Grower). The HiGrade Scope is necessary for the Pro features to work; this is because it turns your phone into a microscope, allowing you to capture images of the trichomes and other microscopic structures on cannabis flower. Our algorithms analyze these structures to evaluate the cannabinoids content in your flower (for the Potency feature), and to accurately predict harvest timing, detect pests and more (for the Grower feature).
What if I already own a magnification device, can it work with the app?
Unfortunately, the answer is no. The HiGrade app & algorithms were trained to work specifically with the HiGrade Scope. Although similar models exist on the market, we manufacture the HiGrade Scopes which we ship to our users, and oversee strict specifications and QA, assuring it will fit our service. In any case, to unlock the Pro features you would need the app activation code that’s included with the HiGrade Kit alongside the Scope.
What does HiGrade mean?
High-grade is an old school slang term for high-quality cannabis, still used today in cool places like Jamaica. Since we developed a Hi-Tech system to grade cannabis, we fused them together and got HiGrade 😊
Why should I care about potency testing?
Cannabis flowers vary in potency tremendously, even if they are taken from the same plant. In order to properly dose its consumption or to know how much it’s worth, cannabinoid content is usually the number to look at. Since cannabis testing today (through HPLC) is destructive, only 0.5% of flowers are being tested. This means that labels on cannabis flowers are usually misleading, and there’s a need to test flowers individually to know what’s their potency.
How can you evaluate %THC from a picture?
Over the last few years, we have developed a patent-pending method, by which image analysis algorithms analyze magnified cannabis images to evaluate THC percentages. The magnified cannabis images contain trichomes and other microscopic elements we use to evaluate the potency with. Our patent-pending method is tested with HPLC, regulatory approved labs. Three photos from different areas of the flower are required (to account for in-flower variability), which we then analyze on our secured servers and send the results back to your phone in just a few seconds.
What is the accuracy of the Potency test?
The current deviation average (RMSE) for the THC testing is 15% (statistical), which translate to about +/-3% THC on average. We calibrated our algorithms with many HPLC tests from regulatorily approved labs in the USA and EU. We are currently working on a white paper to be published on our website to elaborate further. This accuracy value is true only when testing dry flowers originating in THC-only strains (normally having less than 1% CBD).
How does HiGrade compare with HPLC tests?
Per one sample, an HPLC test has the potential of being much more accurate than a HiGrade test. However, since an HPLC test is destructive, and cannabis flowers have natural variability, labeling an entire batch on a single HPLC sample can be misleading (see “Why should I care about potency testing” section above). Moreover, there have been reports on a deviation in results between different HPLC labs, due to different calibration methods and testing protocols, among other reasons. Finally, in many countries the regulatory standard the labs need to withstand is 85% (statistical), which is comparable with the HiGrade potency test’s accuracy.
Is the HiGrade test intended as a replacement for HPLC tests?
The HiGrade test is not supposed to be used as a replacement for HPLC tests demanded by regulatory bodies. Regulators require potency test in the form of HPLC tests as part of a larger set of tests – mostly ones for ensuring safe consumption (tests for chemical and biological hazards). It is not intended for self-dosage or pricing - anyone familiar with the HPLC method must know it is destructive, so you cannot consume the same flower that was tested by HPLC. HPLC testing is all about batch testing, which may be good for potency testing with concentrates (since they are homogenous), but not for the botanical product (cannabis flowers) which are inherently variable. Labeling an entire batch based on one test - not accounting for that variability - is misleading the public. This is what HiGrade tries to correct - we provide an evaluation for each and every flower in a non-destructive manner, empowering consumers to really know what they are putting in their body.
Does the test damage the plant in any way?
Not at all, you’ll just be taking photos of it using your phone's camera.
How long does the test take?
Depending on your internet connection, it can take as little as 5 seconds, and usually takes less than 30 seconds.
What happens if I test a CBD plant?
Since our algorithms trained on plants from THC-only strains (normally having less than 1% CBD), testing hemp or high CBD plants may result in less accurate results. We are working on a test that will enable to test CBD flowers as well, but in the meantime, know that the HiGrade test is intended for use with dry flowers, from THC-only strains.
What are trichomes?
Trichomes are tiny, hair-like organs on the surface of leaves. They are sometimes referred to as "crystals" or "frost" on cannabis flowers. In fact, many plants have trichomes which they use for chemical or physical defense, among other uses. Most people don't even know they're surrounded by trichomes all the time - a little-known fact is that the cotton we use for fabrics, clothes, etc. is actually a bundle of trichomes the cotton plant produces. In cannabis, trichomes are the major "factories" for production of THC, CBD and the rest of the cannabinoids.
