As a Cannabis medicine maker and educator, I get asked all the time about the various machines on the market designed to make your DIY Cannabis remedies even easier and more potent.

So rather than answer each person individually, I thought it made more sense to compile all my thoughts here so that everyone could benefit.

I want to preface this post by saying what I tell all my students — that you don’t NEED any of these machines to make your own Cannabis remedies. People have been extracting cannabinoids for millenia without the aid of fancy technology, and we got along just fine. In fact, in my Cannabis Alchemy course, I describe some other tried and true ways you can extract your flower into oil, alcohol, edibles, and topicals using equipment you more than likely already have at home.

But for those who plan on making a lot of their own infusions, investing in one of these machines makes a LOT of sense. They take a lot of the guesswork out, produce a more consistent finished product, and will actually SAVE you a ton of money in the long run.

So without further ado, let’s talk gadgets.


The Magical Butter Machine


This was one of the first extraction machines to come on the market during the cannabis legalization wave, and it remains one of my favorites.

The Magical Butter Machine is basically the groovy love child of a super precise crock pot and an immersion blender. It has a number of temperature and time settings to help you fine tune your creations, ranging from no heat up to 220° F, and from 1 hour up to 8 hours.

Once you’ve fully decarboxylated your flower (more on that below) you simply add it to the machine alongside whatever liquid you’re choosing to infuse (my personal favorite is coconut oil, but you can also use any other oil, butter, alcohol, vegetable glycerin, etc.), pick a time and temp and the machine automatically starts up.

To add to the fun, it will start to flash a bunch of disco lights, and periodically make a loud whirring sound as the immersion blender breaks up your flower and agitates it alongside your oil.

One its finished, you simply strain out your oil and run the machine on its “autoclean” function, and you’re done!

What I love about it:

  • It both heats and agitates your product: We know that both processes assist in more complete extraction, so being able to do both is a BIG plus.
  • It’s durable: I’ve had mine for many years, and even with frequent use it keeps on ticking.
  • It breaks up your product for you: smaller particle size means more surface area, and more surface area means better extraction. Breaking it up while it’s in the oil means that no trichomes are lost to your grinder.
  • It’s one of the more affordable options: It’s still not as cheap as a crock pot, but it’s definitely less expensive than the other options below.

What I don’t love about it:

  • The self-cleaning feature is okay, but I always have to go back and clean it more deeply afterwards. Some particles can get trapped in the little screws underneath the blender piece, so occasionally unscrewing and cleaning those out is needed.
  • It doesn’t decarb: You get a little bit of a decarb while infusing, but it’s not complete, so you need to decarb your flower beforehand.
  • It’s loud: Admittedly, it only makes sound every 20 minutes or so, but when it does it’s pretty noisy.
  • The straining bag is not ideal: It comes with a nylon mesh straining bag, which is great for not absorbing any of your precious infusion. BUT the little folds in the bottom are hard to clean out fully, and the side material starts to crack after repeated usage. I get around this by just using a muslin straining bag.
  • The Minimum line is a bit of limitation: you can’t do less than 2 cups at a time, which makes small batches impossible. However, you can fit up to 5 cups in it, which makes it one of the larger capacity machines out there.

THIS MACHINE IS FOR YOU IF: You’re planning to make lots of large batches (up to 5 cups at a time), are okay with decarbing separately, want lots of control over the time and temp of your infusions, appreciate the benefit of grinding/agitation, and don’t have a ton of money to invest in your technology.

The Original Nova Decarboxylator by Ardent 


This little machine was a gamechanger when it stormed onto the market a few years back. For those who dont know, decarboxylation is the process of heating up your Cannabis flowers to convert THCA and CBDA into THC and CBD, the “active” constituents (Side note: we know there are benefits to the raw cannabinoids, but most research and experience is with the decarbed versions).

Until the Nova was born, most of my decarb happened in the oven, which still gets the job done BUT it makes your house smell like weed. Not only can this be a problem if you have nosy neighbors, but if your house smells it means you’re losing valuable terpenes (the aromatic compounds that are actually a big part of the remedy).

To use this gadget, all you need to do is drop your flowers into the stainless steel chamber, push a button, and wait a few hours. Voila — your flowers are now completely and perfectly decarbed, without so much as a whiff emerging from the inconspicuous little gadget.

AND with the addition of the infusion sleeve, this machine also doubles as an infuser for small amounts of oil!

What I love about it:

  • It decarbs AND infuses: This dual functionality makes the Nova a powerhouse when it comes to small batch infusions.
  • It retains valuable terpenes: By trapping the odor it also increases the potency of your finished product.
  • No need to grind: When I decarb in the oven I grind first to make sure particle size is even. No need with the Nova!
  • AWESOME company with great customer service: Ardent is a fantastic company founded and run by a black woman (so needed in the cannabis industry), and they have a great warranty on their machines. Mine got a crack on its side recently, and even though it was technically past warranty they sent me a brand new machine at no cost.

What I don’t love about it:

  • It’s tiny: While this is great for small batches, it maxes out at 1 ounce of flower for decarb, and around 6-8 ounces of liquid for infusion. Those wanting to do bigger batches will find this machine pretty useless.
  • It doesn’t agitate your flowers: Although the testing data released by Ardent shows great extraction even without this.
  • It has a little design flaw: It has a tendency to crack along the side of the unit where the cap latches on, but as I mentioned above, Ardent has been generous with warranties when this happens.
  • Only one time/temp setting: They’ve got it dialed in for decarb, but it runs a little hotter than I would like for oil infusion.

THIS MACHINE IS FOR YOU IF: You like to make small batches, want precision in both your decarb and infusion processes, and don’t want your house to smell like a college dorm room.

Nova FX


Another device by Ardent, this machine was released in March 2020, and overcomes most of the limitations of the original Nova!

The FX is also both a decarboxylator AND an infuser but with a MUCH larger capacity. It’s able to hold up to 4 ounces of flower, and up to 28 ounces of liquid. Similar to the original Nova, it’s as simple as putting your flower in the machine (again, no need to grind), and pushing a button.

But HERE’s where it gets even more interesting. Research has shown that CBD decarbs at a different rate than THC, and the FX has TWO different decarboxylation settings to account for this, making it’s decarb even MORE precise.

Once your decarb is done, you can seamlessly infuse without the need for an additional infusion sleeve, simply adding your oil and pushing the Infusion button, which is a separate (lower) temp than either decarb setting.

AND since Ardent has been experimenting with being able to bake right inside their machines (yes, seriously) they’ve added a fourth setting, a high temp Bake setting where you can make little cakes without ever turning on your oven.

What I love about it:

  • Bigger capacity, and no minimum: This was a major limitation of the first Nova, and this machine more than makes up for it. It’s still not as large as the Magical Butter, but it gets close. And a big bonus? You can still decarb and infuse smaller amounts in it — there’s no minimum capacity to run the machine.
  • No need for a separate infusion sleeve: You can decarb and infuse right in the same place.
  • It’s dishwasher safe! None of the other machines can boast this, and it makes clean up a breeze.
  • Multiple temp settings: Not only does it make the operations more precise, but leaves some room for creativity and experimentation.
  • Comes with a cute carrying case! This is functional, too — the case protects it during travel which is something none of other machines have. Pretty important for an investment like this, I’d say.

What I don’t love about it:

  • No agitation of material: But again, this just might be my inner herbal curmudgeon that wants all extractions to be agitated, because their testing data shows great results.
  • Slight smell: This might be my super sensitive nose, but I feel like you can smell odor slightly more with this device than with the original Nova. But it’s really only when you’re standing right over it, so most of the terpenes are staying put.
  • It’s spendy: It’s the most expensive of the infusion machines

THIS MACHINE IS FOR YOU IF: You’re serious about making amazing Cannabis medicine in your own home, have some money to invest in this,  like easy clean up, and want the best all-in-one solution for both decarb and infusion (and baking!)

WHERE TO GET IT: Head here to buy direct from Ardent! And be sure to use coupon code CANNABOTANICALS to get $30 off your purchase! (Price = $350, $320 with coupon code)


So there you have it, folks. There are a few other machines out there that aren’t included here, but these are the ones I have the most experience with and find to be the most helpful. Each gadget has its pros and cons, and so it really comes down to your preferences around medicine making and what’s going to be the best machine for YOUR lifestyle.

  1. I’m still learning from you, but I’m trying to reach my goals. I certainly enjoy reading everything that is posted on your website.Keep the information coming. I liked it!

    1. Hey Mohamed! So I haven’t personally done it since I prefer to do cold infusion on my alcohol tinctures. The infuse cycle peaks at 176 F, which is higher than the temp that alcohol evaporates, so i wouldn’t risk it.

      1. Alessandra Boza

        Hi Stephanie,
        I’m all new to this. Want to star playing around and experimenting with making some oils with.
        Can you use a pressure cooker? If so, what kind of liquid would you use. And can I use the leaves of the plants I have instead of flowers?

        1. Hey Alessandra! I haven’t used a pressure cooker personally, but I know someone who tried it and ran the test results — it performed pretty poorly.

          You can absolutely infuse the leaves of the plant, but they are much lower in cannabinoids than the flowers. The sugar leaves closest to the flower will be the most potent.

  2. Are there any alternatives to the Nova unit? I purchased a few many years ago, and customer service was TERRIBLE. Design flaws & breakdowns necessitated returns, which were not honored. Also, I had to wait many months to get replacement unit. Has their customer service improved since 2015? Are there any competitors (please!). If not, why not? Thanks.

    1. Hi Diane! Magical Butter has a decarb box that you use in your oven, but I haven’t personally tried it. The Levo II supposedly has a decarb function as well, but I’ve been underwhelmed with that machine’s infusion ability.

      I’m sorry to hear your customer service experience with Ardent was bad. For what its worth, the Nova FX seems to have improved on the design flaws of the original design. I haven’t had a difficult time contacting them until recently — I think they’ve been overwhelmed with demand, plus the challenges of COVID.
