Hydrology 9 Review

8.6 Total Score
Bottom Line

The Hydrology 9 is a cool, futuristic looking dry herb vape with a litany of impressive features, the most notable of which is the water-cooling feature that gives it a bong-like experience. It also has an integrated stirring tool and cool LED lights. What it doesn’t have is strong vapor quality. The water does a great job of cooling down the vapor, that vapor is good but it is not as strong as other vapes in this class. If it wasn’t for the price, this would be a great vaporizer for beginners, as it is, tech-loving vapers are the main audience for this one.

Hydrology 9 Review

Hydrology 9 Background

Just one look at the Hydrology 9 and you can see that it is one of the more original dry herb vaporizers on the market. It has water filtration, an LED light show, an integrated stirring tool, and other advanced features. They aren’t just for show—well the light show is, of course—because they’re meant to provide a next-level vaping experience to go along with the Hydrology’s next-level looks.

It doesn’t quite reach the next level, but it is certainly on a different level compared to other weed vapes. Is that a level you want to be on? If you like flash and lots of interesting gimmicks, then sure, but if you want a really strong vaping experience that can match the best weed vaporizers, then probably not. You’ll get more details in the rest of my Hydrology 9 review.

How it is Designed

Hydrology 9 Design

The LED lights create a very nice light show when reflected off the water in the chamber.

The Hydrology 9 is one seriously unique looking vape, it’s a big cylinder-shaped device that consists of four parts, the base where the battery, herb chamber and heating element are located, the glass chamber that holds the water, the glass mouthpiece, and the metal mouth cap. Magnetic connections mean that it is very easy to assemble, which is good because assembly and disassembly can be a time-consuming process, especially when you include the filling and emptying of the water in the glass chamber.

The Hydrology has some cool built-in features, like the stirring tool built into the base that you can use to swirl around the herb while you vape. You can adjust the air intake to alter the draw resistance, which is a nice feature. Also, there are multicolored LED lights in the chamber that correspond to the five different temperature settings. They create a nice show when they reflect off the water in the chamber.

This vape might be classified as a portable but it’s about as pocket-friendly as a refrigerator. When you consider the lengthy loading and water-filling process, you quickly realize that this isn’t really a vape that you can take with you, even in a backpack. The Hydrology 9 is pretty much the definition of an at-home-vaporizer.

How It Performs

Hydrology 9 Performance

The vapor density and flavor produced by the Hydrology are both rather mild.

With the long vapor path and the water chamber, you would expect that the Hydrology produces some extremely cool vapor, no matter which of the five temperature settings you choose. And you would be right, this vaporizer is very easy on the lungs. Perhaps a little too easy because the vapor and the flavor are both very light. That is great for beginners or for anyone using the Hydrology for medical purposes, but experienced—or even casual—vapers will enjoy the flavor, but seasoned vapers will be disappointed that the vapor is not as strong as other vapes in this price range. I felt the effects of the vapor, I just didn’t taste it much.

The Hydrology holds a surprisingly small amount of herb considering how large it is, just about half a gram, if you are a regular vaper, then you will be refilling it a lot. As I stated earlier, disassembly and reassembly is easy but time-consuming, and needing to refill it all the time can become a chore.

Battery: The Hydrology has a 2000 mAh rechargeable battery that can last for about ninety minutes, but it takes nearly three hours to get charged.

The Final Word

The Hydrology 9 is an impressive feat of engineering that has a cool look, some cool features and some good vapor, but, unfortunately, that vapor is not as strong as I was expecting. It’s not bad, it’s just really mild, which makes it unsuitable for seasoned vapers, but just right for beginners. However, the price is a little steep for beginners, plus the long assembly process doesn’t make it the most beginner-friendly vape on the market.

The Hydrology is a solid vaporizer, but it doesn’t really compete with other vapes in this price point, which is a shame because it has a lot of cool features. I really wanted to like this vape more than I did, the flavor is good, but the strength just isn’t there. Hopefully they can do better in a later iteration, but right now it can’t match the flavor of other hefty home vapes like the Arizer Solo 2 or Mighty.

Hydrology 9

A stylish weed vaporizer that uses water to cool down the vapor


[templatera id=”10619″]

Oron has been vaping for over ten years, and been 100% combustion free since early 2016. He has tried and tested hundreds of vaporizers with every functionality imaginable. Some of Oron's favorite vapes are the Mighty, Solo 2, and Juul. After switching to vaping, Oron experienced first hand the benefits of being smoke-free and decided to help as many people as possible to make the switch. When Oron is not vaping, he is passionate about photography, technology, gadgets, health & nutrition, physical activities.

  1. One of the coolest looking vaporizers – how much when is it available?

  2. I am a triple prosthetic paishint and I’ve den gaping for about 8 years and it gives a string hit without burning the leaves I’m fully bisabled and this is the best and healthiest way to take tour medication

  3. The vape quality is SO smooth with this one. You can take the longest draws and no coughing. I did have to warranty already but they handled the return with a day! I prefer this over the Crafty, when I’m not in a hurry. Also, there is a lot to clean when you have to.

  4. Very cool concept and clearly something most people would love to have. However at this price point it will likely push most people away from purchasing. Get the price down to around $150-$175 with free shipping and it becomes a game changer.

  5. I bought this thinking it would be awesome.
    My first vape purchase.
    It is an REALLY, REALLY, expensive glass bottle.
    I just helped make someones boat payment. Ha ha.
    Works O.K.
    You can turn it upside down.
    I am always afraid of breaking the glass, when I tighten it up so, I can turn it upside down and it won’t leak.
    Tighten up everything and put the magnetic mouthpiece on.
    Then, turn it upside down.
    Then load it.
    Then turn it right side up.
    It goes against everything I have been doing for years.
    Even then, when it is upside down, while I am loading it, some gets through into the mouth piece.
    So when I turn it back over and take the cap off, some is in the mouthpiece area.
    Not much. Two drops maybe.
    Still annoying.
    I have a paper towel I use.
    Really hard to draw until I took the air screen off.
    It hit’s way better.
    Just have to make sure not to spill any when loading it.
    The air vent is right next to the fill hole.
    Battery is lithium and are notorious for short life.
    Mine only lasts for about three to five sessions and then a 2 hour recharge.
    They claim 15 sessions in a charge.
    They don’t even tell you to let it cool down before recharging for longer battery life.
    In 6 months when it won’t charge anymore, what do i do?
    Use it a a paper weight?
    Looked for replacement batteries and couldn’t find any.
    Wish i would have bought one with a A/C plug in.
    Had to keep tightening all the connectors so, it wouldn’t leak outside when I turned it upside down.
    It looks like there is a ball bearing in the mouthpiece.
    Thats the concept.
    To be able to turn it upside down with water in it.
    Not a great concept.
    Poorly designed unless you are rich and need a paper weight.
    I think the guy who designed it was high.
    They need to have the cooling chamber separate from the oven chamber, so you can pull the load chamber off, fill it, then reconnect it with a minimal amount of effort.
    So, there is no water or pipe being turned upside down, right side up etc..
    And an optional A/C plug for home use.
    They will probably design the next one better.

  6. The concept of leak proof is a bit of a stretch. I received a second unit due to a flaw in the bottom seal. Now it leaks less and if I get lucky and put only enough water to cover the holes, It may not leak. But next time I clean it, same problem leakage. Love the unit and the best smoke. But keep a towel handy and more water to refill the chamber.

  7. I am a disabled (going on 15 yrs now) Vet that deals with severe Chronic Pain every hour/every day. Due to my limited, fixed income with a family of 4 to support my financial situation limits my ability to buy things I used to (much less meet expenses every month). When I saw an ad for the Hydrology9, I reached out to Cloudious9 for more info and the possibility of any discounts available. I got a response in 2 hours!
    After receiving info and possible ways Cloudious9 could help me afford purchasing this new, innovative hydro-filtered Vaporizer. I have continued to keep in touch with their customer Rep and they always get back to me the same day, a sign of unprecedented excellence in customer service!
    Since the state I reside in passed (over 65% of public voters said YES!) the Compassionate Care Act to made medicinal marijuana legal, for qualifying and doctor approved patients. I spoke to my doc of 20 years about becoming approved by him for use, because I have been taking OxyContin for 15 yrs, to help ease my pain (only thing that worked for me) and wanted to find an alternative due to long-term side effects and lessening efficacy. He immediately agreed that should try med. marijuana, due to less side effects and long known efficacy for patients with many degenerative diseases, which I have from many serious conditions. He told me doctors have known, for hundreds of years, that Cannabis is effective for many different medical conditions!
    Since knowing I could legally use medicinal cannabis I have been researching the best Vaporizer to use, due to it’s known ability to lesson over 90+% of carcinogens and enhance the efficiency, taste, and harshness of intake, compared to smoking it traditionally. After researching, it’s a known fact that vaporization is MUCH safer/healthier than combustion as a method of using cannabis! The public has been inundated with propaganda concerning the use of marijuana for decades! I’m sure many of you have seen the “ancient”, gov’t funded, propaganda movie “Reefer Madness”. This is just ONE of the many lies out gov’t used, and still use, so Big Gov’t can reap the financial revenue through it’s sale on the “Black Market”! Another Deep State tactic that is labeled a “Conspiracy Theory” to manipulate and deceive public opinion!
    Since contacting Cloudious9, I will be purchasing a Hydrology9 soon! But, I have been able to, discretely, “test-drive” a buddy’s H9 and am totally blown away (no pun intended) by its top-quality construction, innovative new features, and most importantly the function that leads to the BEST vape I’ve even let my lungs enjoy! Being 58 yrs “young”, I haven’t used marijuana since my late 20’s. But when I did, I usually used an Apogee bong filled with ice water. This Vape actually gives you a very similar experience, without the choking and coughing! Vaping Tech has rapidly been evolving in design/tech since Cannabis use has become more acceptable by the public and is legal, rec. & med., in many more states, as the taboos and lies have been lifted.
    I can honestly recommend this new Vape,above any other personally, after using my friends to see and use it in action! It may not be the smallest, most portable vape out there, but I have always been discreet when using “pot” long ago and it wouldn’t take much to transport it, if you don’t just stick it in your pocket. But, as more states legalize it for adults “recreationally”, what’s the difference? Cloudious9 also have a very nice/rugged case you can purchase separately. And it would be a good idea to get one to protect your investment, due to glass components.
    In conclusion, I would like to thank Cloudious9 for responding to me so rapidly and answering all my questions and concerns with honesty and compassion! When inquiring to a vendor about a product I’m interested in, I rarely receive a reply, much less a super fast, honest, and informative one! I can’t overstate how genuine and awesome Cloudious9’s Customer Service has been. They continue to be rapid and helpful, if I have concerns or questions! IMHO…..this is a quality I prioritize, when considering ANY high cost or long-term use product, much less a Cannabis accessory!
    If you consider great CS, as well as quality, innovation, and superior function, and are looking to purchase a Vape, this is THE Vape to carefully consider!
    Again…..THANK YOU, THANK YOU, THANK YOU Cloudious9 for nor only engineering the best Vape on the market, but for genuinely caring and helping me, when I reached-out with questions and concerns!….👏🏼🤝👍🏼👍🏼✌️😁

  8. EXPERIENCED STONERS: This device is cool, but you will not be completely satisfied. The tool kit is flawed, the flathead screwdriver broke the first time I tried to untwist the airduct for deep cleaning, and some of the parts are EXTREMELY HARD to get off. I had to go to the store where I bought it for them to help me get the parts off with everything-BUT the tool kit provided.. Also, you may get high but personally the hits just weren’t strong enough(even on the highest setting). Get something with stronger hits and without a flawed design.
