MigVapor Sub Herb Intro

I know what you are thinking. How come with all these vapor products on the market, nobody has created a good attachment that I can screw on to my mod for dry herb? Truth is, there have been many attempts to create such a product, but at the end of the day they are not actually “vaping” anything but rather combusting, or in other words, roasting your herb.

Introducing the Sub Herb by the folks at Mig Vapor. They have developed a tank that you can attach to your standard regulated vape mod, and vape herb without any exposed coils. The result, is a smooth and flavorful drag that actually hits hard like a bowl, minus the lighter fluid. For $40, that is not a bad deal considering most herbal vaporizers start at around $100 and up. I put this badboy to the test and was pleasantly surprised by it’s performance. Let’s take a look at this brand new product by Mig Vapor.

Notable Remarks

There are a few things to know before using your Sub Herb device. I would start by applying a little bit of e-liquid to your o-rings so that you can get the glass on and off rather easily. Then pack a good amount of herb, but not too much. Next, start off at around 19W and pulse your fire button for a few seconds on and off until it heats up, or else you won’t get a good hit. Make sure to not hold the fire button for too long or you can damage the device. Take a break between bowls. Once you feel the vapor production dropping off, remove the glass and pack the excess material down with a small tool or just your pinky finger. DO NOT exceed 27W!

It literally just looks like a regular sub ohm tank with green o-rings. The white herbal cup in the middle will start to discolor with use, which is completely normal considering that it is pure ceramic. The entire tank comes apart making cleaning it an easy task. Overall, it looks good.

Vapor Quality

If you have ever tried an herbal vaporizer, especially the portable kind, you probably have experienced that weak hit that you typically get from those. This device is different. Is it 100% free of any combustion? I’m not totally sure. It is almost hard to believe that you are getting purely vapor, but I am not a scientist when it comes to that kind of stuff. According to Mig Vapor, it is in fact pure convection. All I know is that it hits hard as hell and produces some decent cloudage. Essentially, the ceramic oven will bake your herb as opposed to roasting it.

The Sub Herb has a nice weight to it, so it does not feel cheap. Mig Vapor takes pride in the fact that they use Pyrex glass and stainless-steel, which in turn makes the product durable. The only thing that I am going to say is be careful not to overheat this tank. You will run the risk of cracking the ceramic heating cup. If you feel it getting too hot, just take a little break.

The fact that you can use your existing mod with this device bumps up the convenience factor by a lot. Also, the actual tank is tiny, so it can fit in your pocket. Once it is packed, you will get a few hits before having to open it up and push down your material to get that last bit of vapor, so that is pretty sweet. The fact that there are no exposed coils is another plus, making this device relatively easy to clean. With a cotton swab, you can get it looking brand new again.

This little device is quite efficient. You can vape herbs until there is virtually nothing left. The ceramic cup creates an oven for your material until it is completely vaporized. You will get the most out of your dry herbs because this tank wastes virtually nothing. Apparently there is no combustion going on as long as you stay within the recommended wattage range (19-27W).


For the price, it is actually a good value. Considering most vaporizers and herbal pens go for more than double, sometimes triple the price. This is great for somebody who just wants to stop smoking and just vape their herb, without having to buy a whole new setup.


  • Holds a bowl’s worth of material
  • Satisfying and effective hit
  • Non-exposed heating coil
  • Fits on any regulated mod that can fire up to 27W
  • High-quality construction
  • O-rings hold very well (I recommend lubing them up with some e-liquid if possible)


  • Rather tight, non-adjustable draw
  • Mouthpiece comes out easily
  • Ceramic cup non-removable (replacement base goes for $15)


In conclusion, I like this device. It is great for people who want an attachment that can do dry herbs and concentrates on their existing regulated vape mod. Yes, there are a few minor things that could be improved but to be honest with you, there is really nothing on the market quite like this. I hope that the Sub Herb inspires a whole new trend of tanks that you can attach to your mod for vaping herb. For the price, you really can’t go wrong considering that Mig Vapor stands behind all of their products with their warranty. Has anybody tried this device out yet? We would love to know what you thought of it in the comments section below!

    Nope. Mind you, I am an extreme noob to herb vaping, so take my *take* on this gadget with… well, a grain of salt.

    #1: Quote from the article – ” I would start by applying a little bit of e-liquid to your o-rings so that you can get the glass on and off rather easily.”
    I actually found that the glass comes of very easily. Too easily. If I’m not very careful, I found that the *tank* has become unseated by just… whatever. Mind you, the ease of removing the tank is absolutely Fantastic when refilling! Just be SURE the tank is seated tight before vaping!

    #2: The amount of herb. Didn’t matter if I packed this thing with 1/2 full or full or packed, My draw was limited. The vapor was limited – which, imho, , is a good thing – since clouds are NOT what I want with vaping herbs. Anyhoo, if I put more than 1/2 full, I always end up with the top half un-vaped. Stir it, you ask? Try doing that. Even with a piece of folded paper underneath, I always resulted in more erb on the paper than in the wonderful ceramic bowl. And then try to get that detritus back into that very same bowl? Good luck.

    3#: Quote from the article – ” All I know is that it hits hard as hell and produces some decent
    cloudage. Essentially, the ceramic oven will bake your herb as opposed
    to roasting it.”
    “Hard as hell” is, to me, an understatement. I can take a hit off a spliff, a bong, even a hookah and still get the same hack-cough. It is rough. Cloudage? wtf are you even talking about such a thing with herbal vape?? geez… “bake your herb”? Well, when I look at what is left after “vaping”, I am slightly more inclined to say “combustion”. But, that is me.

    #4: Well, like I said, I am a noob. But. I tried this thing at various wattages. From 10 up to 20, in increments of 2.5. Higher watts meant a burn in flavor after 6 seconds. Then I got nada. No flavor (actually, never was), no nothing… ie. cloud. Crank the watts and I choke with a 2 second pull. But hey, I haven’t done herb for decades. (smoker for 40 years and a vapor for 2+)

    #5: Heat. My tank gets hot. My mod gets hot. It is suggested in the article to “take a little break” if the… hm, never mentioned about what gets hot. I just stop altogether when things get hot. Past experience. Comes from being 50+.

    #6: Hits? No. I could get two, maximum, hits before having to open the thing up and DUMP whatever is left and reload. I keep the leftovers to use the old-fashioned way, in a bong. Which kinda defeats the intent of the Black, hm?

    1#: It is very easy to use. Even with my tremors, I can load the ceramic bowl fairly easily since it is quite large. That is a bonus for this ol’ boy.

    #2: Even tho’ the hits are harsh (for me), my herbs end up doing exactly what I intended them to do when using this MigVape Black. And that is really truly the ultimate intent of the thing… or at least, why *I* bought it.

    #3″ The gadget comes with cotton string for… for… what? Oils? Wax? I dunno. Waste for me. But it’s there. And you also get this amazing little round rubber ring to…….. uh, well, even the book that came with doesn’t explain wtf that is. Ooooo, and extra screens in case you don’t know how to clean – replace – make your own. woo. hoo.

    OK. I’ll end here. It works. Vape vs Combust? Unsure on my part. The beauty of this is that I no longer need to rely on a separate dry herb “vaporizer” to do what I love. Ignoring the fact that I have discovered how to make my own herbal juice….. well. I guess I offer this tank a 5 outa 10. Am I happy with this? No. Not what I paid for it. Not for the (see below) BS I went thru to get it.
    UNDERSTAND!!! I have had an extremely BAD time with the supposed customer service at MigVape. I dislike the company. No, I HATE the company. I will never EVER deal with them again. If this thing ever fails in the next 30 days, I will garbage it. MigVape isn’t worth any effort from here on in. On my part. Me. Got that? ME!

    I used this on an iEleaf iStick 30W. That is my only mod and I do not wish to change.

    Final word. Not impressed. If CS gave me some satisfaction, I’d almost offer an 8 outa 10. Almost. So. My Score: 5 / 10
