I’m excited about this discussion today - I bought one of your devices. Does it work on other liquids - specifically honey?

Hello Cheryl,

Thanks for joining us today!

We are currently working on other liquid infusions and have received a number of requests for honey. One of the specific challenges we’ve run into is that certain liquids, such as EVOO and honey, is that they have a fairly broad spectrum of base absorbancies. One of the features that we will be rolling out in the near future is the ability to tare or zero out your baseline oil. Honey will require the feature in order for the readings to be accurate.

Thanks for being here today!

What applications are your products presently geared toward?

Our roots are in the edibles arena so there are quite a few edible makers out there using this device. Our recently introduced flower & concentrate add-on kit has been quite popular. That allows growers & extractors to measure their products as well.

So this is an attachment that works with a users existing device that allows for measuring of what exactly in flowers and concentrates? Terpenes and cannabinoids? Myco?

Yes it is a kit to test for THCa potency in flower and concentrate.
Sorry, it doesn’t test terps or pesticides at this time.

As an example of how your tCheck device works, can you give us a short description of how one of the most common tests is performed?

That’s awesome!

Are there any plans to integrate these tests in the future?

I am a industrial hemp farmer, specifically growing for CBD, does this product work with testing for CBD as well, and making sure that my thc levels are below the legal requirement?

Great questions, @stevo47 and @sedowicz! Thanks for jumping in on the AMA!

  1. Connect your tCheck to your phone via Bluetooth LE
  2. Place 3-4 drops of your infusion into the tray
  3. Insert the tray into the device and follow the instructions on the app
  4. Results will be displayed in the app in about a minute

For oil infusions and alcohol tinctures, results are displayed in terms of mg of cannabinoids per ml of liquid. For example, 7.5 mg/ml

That sounds super easy! I want to try one of these things in my grow!

It does test for CBD but 0.3% THC below the device’s ability to measure. :frowning:

Does it measure delta 9 thc as we do not decarbulate?

4 Likes

Yes, it does measure both THCa and THC.

How does it work with edibles?

Great device! Do you think it’s accurate enough (in testing potency) for laboratory testing centers or, perhaps, a dispensary to test the final products they sell? Thx.

Is this able to be calibrated? If so, do you provide the solution for calibration?

Yes. Our team is currently working on a pesticide tester. Some of the labs we’ve spoken with have mentioned a few of the more common pesticides, including:

  • Myclobutanil - triazole
  • Imidicloprid - neonictinoid
  • Abamectin - avermectin
  • Organophosphates (chlorpyrifos, dimethoate)

Which pesticides are you most concerned about?
