Get HiGrade test or kit

I’m kinda new to all this and to have a device that does what it’s meant to do is be official to the needs of the community and so far this device has impressed me and I’m looking forward to the next grow season as well to utilize the other features the grading of finished said strain and testing of thc to me are close and with in the +/-3% range.

The only reason I give the app a 4/5 is I would like to see the app eventually have an update for it to tap into a data base even if on our end have to type in indica,sativa, or hybrid with that knowledge it then is capable of giving the name
I feel if the company asks the user of the device to upload the data taken from our end would help the team create better algorithm and or names lists of the strain I know I wouldn’t mind as long as data only pertaining to said strains no data of the user what so ever

Great app!

I have the pro edition for a legal medical home grow, and it's a surprisingly good tool.
I tested some dispensary flower, and the results were consistent with lab test labeling through a few tests from each jar examined.
I believe an estimated percentage (plus or minus three) provides a more accurate range for my purposes, since the potency will vary throughout the plant.
The grading feature (free version) is also cool. Aside from just checking dispensary bud quality, it's nice to be able to get impartial input on the quality I'm producing myself and see that it's at least as good as what I could buy.
While $80 ain't cheap, it's really for a full year subscription to to THC tester and grower advice (you send a pic & question), a much more exhaustive strain catalog than online sources, and is considerably less than other testing options.
The more folks who use it, the more training data for their AI, and everybody wins. If you're growing at all, I'd strongly recommend it.

Works so far

My wife found this awesome device and so far I’m impressed. It provides a margin of error for the THC approximation. And given that margin of error it has been within acceptable tolerances it has matched what the dispensary test results say. Excited to know what level our home grown is coming in at. This is a must for people needing to find specific numbers for their different methods of enjoying their medicine.
