MagicalButter DecarBox Product Overview

The MagicalButter silicone decarboxylator comes with great packaging. The instructions are also clear and of the same high quality, we had come to expect from the MagicalButter machine. The products itself feels solid. However, it does not come with batteries. (You will need two AAA batteries.) The sensor cable also feels solid, but ours did have some bends in it that were already fraying, so we kept those out of the oven. The temperature readout device has a magnetic back, which allows it to stick to your oven door easily.

Product Operation – Standard Oven Decarboxylation

Step 1: Oven Calibration

Unfortunately, our oven was being extremely difficult throughout this procedure. When we set the oven to 245F the thermometer read 260F, and at 240F it read 240F. We could only choose those 5-degree increments, so there was no way to set it to our desired 252F.  

From Stem’s engineering background, he felt that the sensor refresh rate on the thermometer was a bit too slow – meaning that the sensor is not the highest quality sensor. At this price range, the sensor could be a bit more responsive. But it still reads the temperature, so it seems like the quality of your oven is more of the controlling factor than the DecarBox, but the thermometer certainly is helping and giving some confidence in the process. It just doesn’t help you tame a stubborn oven.

Step 2: Decarboxylation

We let the oven heat up at the 245F setting and then dropped it to 240F. The temperature began to drop from 260F and once we saw the thermometer reading 252F we took the empty DecarBox out and filled it with the cannabis. Even though the DecarBox is a bit floppy due to being made of silicone, it did go in the oven easily. We do recommend you use oven mitts because it gets hot!

The readout temperature continued to drop, and in essence, we had no added control of the temperature. Obviously, the product is not intended to help with controlling the temperature of your oven, so for us it just frustratingly let us know there was no way we could set the temperature to what we needed for an ideal decarboxylation.

The device caused a bit of anxiety and made me work a lot to keep changing the temperature to try to get to a steady 252F. While we did not manage to decarb at a specific temperature for the whole time, we at least have the confidence that the process took place in the correct temperature range. Next time we think the better thing is to choose a temperature and pick the decarb time from a decarboxylation curve to optimize the process at that temperature.

Step 3: Cannabis Cooldown

As the manual suggests, we took the DecarBox out of the oven and put it straight into our freezer without opening the container itself. We left it in there for 15 minutes. The decarboxylated cannabis looked amazing and smelt incredible. By far this was the best cannabis we ever decarbed. This is likely due to the container being airtight – unlike our pyrex with tinfoil in our first try. A bit of the flower and trichomes were stuck to the silicone sides, and I could not get them off of it but not a significant amount lost.

Overall User Experience

This product attempts to solve two key issues with decarboxylation at home: keeping the cannabis in an airtight container and ensuring that the decarboxylation takes places in the proper temperature range. The silicone DecarBox is absolutely a great container for decarboxylation. Not only is it easy to pack and seal, but it also keeps the scent locked in even more than what we used in the past. The temperature sensor is very helpful in allowing you to see what your oven’s temperature is, but it does not help you control your oven. It is definitely a benefit to see the temperature readout, but your oven is truly the controlling factor. We were not able to have our oven stable at 252 F no matter what we tried. For optimal results, we suggest referring to a temperature-time chart to check how long you need to decarboxylate at the temperature your oven is steady at.

Does it improve the MagicalButter experience?

If you are curious about how to use the MagicalButter machine in general, please refer to our review :

Click to Read Nug and Stem’s Review of the Magical Butter

The biggest ambiguity we had when using the MagicalButter machine was that we were not confident in our decarboxylation procedure. We had no way to be confident about our butter potency. While the DecarBox does not necessarily allow you to calculate your potency any more accurately – that is a very difficult thing to do without a laboratory – it allows you to be confident that you are decarboxylating at a proper temperature for the proper amount of time. This definitely helps you protect your investment and ensures a quality end product. So the DecarBox definitely improves the MagicalButter experience!

Nug and Stem Cannabis ReviewsNug & Stem Review
We are a couple that enjoys regular cannabis consumption and has a passion for sharing that enjoyment. I, Nug, am a petite woman who consumes cannabis more sparingly than Stem – who is a man and a more experienced user. Medically, I use cannabis most often to help treat anxiety, so I tend to reach for strains and products with higher levels of CBD. Stem uses cannabis to relieve chronic back pain caused by sports injuries, so he relies on a wide array of products depending on whether he needs help being active, falling asleep or needs instant topical relief. Medical uses aside, we do also enjoy using cannabis recreationally with friends and would like to contribute to normalizing this amazing plant. Visit us on Instagram @NugAndStem
