Hey we’re glad to see that this thread continues to gain traction and appreciate the discussions and feedback. We also wanted to thank our early adopters for supporting us during this exciting but chaotic startup phase and are really touched that you can see that we are dedicated to making a difference in this industry and pushing for more people to have access to this awesome plant. A few responses to some questions we saw pop up:
I wonder if you could decarb concentrate in a shot glass with the Nova? That would be cool.
You absolutely can ☺ you can also use multiple shot glasses to decarb different strains of kief, rosin, or hash at the same time.
I'm sure the comparison side-by-side between the Nova and an oven has a minor differentiation (unless the Nova website illustrations about THC yield are correct, then you are at an efficiency loss). Certain dependencies would accentuate those differences, such as: sustained, accurate, and consistent temperature, odor production, ease of use, and consistent, overall decarboxylation. The Nova website does have some cartoon graphics illustrating THC yield percentages, but I did not see any side-by-side experimental data.
For our initial
decarb guide (something that was intended for wide audiences) it was important to present the data in easy to understand and digestible form, hence the illustrated graphs. Of course we have raw data, and since there have been requests here, we are happy to share those testing results. We’ve developed a section of the site that we’ll continue to update as we continue our R&D on Nova and the new products in our pipeline.

A summary of what we’ve added so far:
Comparison of Oven, Toaster Oven, and Nova Decarb
Raw Cannabis Max Potential THC: 18.1%
Oven Decarb 240F for 40 minutes Max Potential THC: 15.3%
Toaster Oven Decarb 220 for 60 Min Max Potential THC: 12.2%
Nova Prototype Decarb Max Potential THC: 17.9%
Here we see a significant loss of THC in both the oven and toaster oven decarb. However, the results using the same temp settings in a different oven could just have easily shown a failure to convert all of the THCA. The point is that ovens aren’t constructed to maintain the precision in temp needed for a full and protective decarb but instead easily swing above and under the tight parameters required for complete decarb with no loss. While there may be some folks who are getting good results after trial and error, monitoring, using high-end ovens, temperature probes, who may not care that much if they are experiencing some loss - having an easy, foolproof (and smell proof) way to know the decarb is being done right is exactly what many patients need.
*Also note when reviewing that early Nova prototype achieved 95% decarboxylation. The process was further refined during development to currently deliver full (>97%) decarb each time.
Nova Shatter Decarb (for the concentrate lovers)
Raw Shatter Max Potential THC: 72.2%
Decarbed Shatter Max THC: 79.2%
Shatter can become slightly more concentrated during decarb due to the evaporation of residual solvents.
Nova Flower Decarb 2
Fresh Raw Plant Max Potential THC: 15%
Decarbed Flower Max Potential THC: 16.9%
When decarbed, fresh uncured flower also becomes slightly more concentrated due to the evaporation of moisture during the process.
Nova Flower Decarb 3
Dried and Cured Raw Plant Max Potential THC: 18.8%
Decarbed Flower 1 Max Potential THC: 19.2%
Decarbed Flower 2 Max Potential THC: 17.7%
This third testing set demonstrates the natural plant variation that will be observed in some results. As a natural product, slight variation in the plant material is to be expected, even slight differences within the same bud, depending on which parts of the bud were closer to the light, or whether a small piece of sugar leaf is attached to the bud, just as a few examples. In our observations, variations in the plant usually fall within +/-1.5% of each other. There are also variations that will sometimes display in comparing single testing results. In the lab setting, these standard deviations are accounted for by using multiple testing points.
The testing set above includes variations within the normal range. The raw sample testing at max potential THC of 18.8%, with the first of the two decarbed samples that are also from the same bud as the raw sample (decarbed together in the same device at the same time) testing at slightly higher max potential THC of 19.2% and the second decarbed sample at a slightly lower Max potential THC but with all falling within 1.5% of each other. Large differences, however, (especially reductions) in max THC percentage indicate loss during the process, as well as >1.5% differences that persist over multiple testing points.
Stay tuned for additional results added over the next few days.
