I have recently realised I am starting to use my solo as more of a conduction vape than a convection vape. So I have started to think about conduction vapes, what are the contenders at the moment? I am open minded to style and price at this stage, so what do FC'ers use.

Well I don't have a Solo so I'm really not sure how it's possible to choose conduction verses convection.

Most every vape uses a combination of the two to achieve vaporization. Usually the convection aspect is on portable vapes is rather limited to the heat as it transfers through the load while hitting it.

And then there are vapes like my Enano which are purely convection vapes - yet they perform better if you allow a bit of conduction heating through letting the nano "heat soak" the GonG stem before you start hitting.

The real question is why do you want a new conduction vape? Is it for the taste, efficiency, portability? what?

My Indica is a great semi-stealth vape which is almost purely conduction - and it produces a very "roasted" flavor. Yet my Davinci Ascent with it's glass on glass vapor path and a conduction oven (with some mild convection) produces the best flavor of any vape I currently own.

OK the why first.
With my convection only vapes ( logs/ LSV/ solo) I find the continued inhalation of pre heated air was drying my throat out and causing irritation.
With the solo, the stem sits in the heater and allows the heat soak effect that you have noticed in your nano. With the heat soak every thing comes up to an even temperature requireing less air flow to complete the extraction. Also I have notice the ABV is roasted evenly without stirring which I think may allow for even higher roasting temperatures to be achieved without the risk of combustion.
Another benefit is with the load at full temp the first hit is the closest thing I have found to the combustion feeling that smokers crave when they first start vaping.

Fair enough, those are some valid opinions.

The indica is a nice vape, though I find I sacrifice taste in exchange for stealth. But it's a fair tradeoff for my portable vaping needs (the taste is better than a pax IMO).

I was thinking the Ascent might be a good option, but I get a very dry mouth when using it dry. I need water filtration especially with that vape to make it enjoyable (though in reality, I almost always use water unless it's in a mobile situation).

Have you considered the Lotus vaporizer? I know it's a pure convection vape (stainless steel WPA cuts down on conduction heating dramatically). But it's been the closest I've come to recreating my previous habit of combusting with a pipe. If it weren't for the practice required to get proper vaporization (without possibly combusting!), it would be the perfect vape to convert combusting friends. combustion is easily achieved when you're inexperienced, but once mastered, holy hell it's an amazingly efficient vape.

I have a home assembled vape that works very similar to the lotus but has the usual convection traits.
I was looking at the vapolution as it looks like the load sits in the oven. It just comes across a little janky so to speak even though it looks the goods.
On the portable side the pax does come close.

That would provide radiant heat, if left in the chamber long enough, but since the heat chamber is separated from the bowl by air, there is no conduction, and if you hit as soon as you insert the bowl, it's all convection. The Vapo 2.0 has a learning curve, and you always have to pay attention when the bowl is in, but once you get the hang of it, it's a really enjoyable vape and arguably the best buy in a home/semi portable on the market.

It's really hard to find a 100% conduction vape, and conduction all the way doesn't measure up to convection for efficiency.

I think mix of radiant/ conductive heat would allow for the load to reach the required temps (you could achieve very accurate and stable temp control) and then use convection as the delivery method.

Probably not very helpful, but have you had a chance to try the supreme vape?

Not exactly in production right now, and it's more convection than conduction, but I always find if ya heat it up relatively hot, then the heat would transfer down a bit and start to preheat the load, so you'd get nice, thick, vapor, with relatively little "pre heat air".

No stirring required.

Most peeps that have one are quite fond of em, but I have seen them pop up on the classifieds from time to time.

I thought there might have been a little more variety out there.
With the rapidly evolving technologies who knows how we will consume in the future.
I still think the vapo might be some thing close to what I am thinking about.
In the mean time I guess I will just continue as is.

Good thread @4tokin

This has been my finding as well.While I enjoy convection for its clean taste.I am enjoying conduction more so than convection hits lately.i can't see me returning too smoking because taste and flavour are so good with vapor, not to mention the considerable health benefits.

Are you interested in the differences between convection and conduction vaping also? Or just interested in finding a good conduction vaporizer?

You mention smoke like effects..can you summarise those effects You look for briefly if you don't mind?

I have tried numerous vapes and also have a workspace where I play when I have time.its become a bit of a study.it fascinates me being honest. 4 years or so since I began hearing about vapes on the chasing the hangman site just browsing....i almost bought one ..glad I didn't:)

I use the Vapman for the particular effects I get from it.the flame powered vape is my goto conduction vape It gives good sedatory conduction smoke like effects I look for.its practical and uses a steady power source,a jet torch.
If I use my little vapman enough continuously,I will pass out:zzz: :D Which sometimes, I need to switch off and get a good nights sleep.
It's a one hitter, tiny load size,is efficient and flavour doesn't deteriorate because you mostly finish what you load in a session.

Other vapes I know of with conduction properties are pax, iolite,wispr.
The Arizer extreme Q has a glass herb chamber that constantly sits over a heat element so will conduct heat into your herb if left for a while.I always elbow packed as I found the EQ tuff bowl too inefficient when vapingon my own.log vapes or similar will work if the stem s left to soak for a while.

The new storz and Bickel crafty is marketed as a partly conduction vape too.It looks like it could work well.i haven t seen the design of the heater so it's hard to give a verdict.its literally 3 days old and designed by a team with lots of experience.there are eight or so convection air inlets underthe bowl which should provide good convection extraction also.it remains to be seen if the bowl is an independently heated oven or is heated through convection.

Lastly,The indica and the flowermate too are conduction vapes.MFLB also uses conduction effects.

there are many others.these few just popped out of my head while I was posting this.
Be interesting to hear you're findings in a little more depth some time.

I have enjoyed convection for a long time and am discovering conduction and am starting to explore its potential.

With convection your load starts off at room temps and you start with wispy draws, and as the load heats your vapor thickens. With the conduction principle you put your load in the oven to pre heat and once it has reached the desired temp you draw all the the vapor particles in one dense draw.
That one dense hit is what I feel is the closest I can come to combusting with a vape.

There is a lot happening in the market place at the moment and I feel that a lot of producers are over complicating things so they have the latest and greatest solely for market share.

In the meantime I will continue pondering and tinkering.

Have you looked into the sublimator at all?

It seems to have a decent amount of pre-heating going on, and I believe most users extract just about everything they can after only 1 hit.

This would be my recommendation.

Another consideration for conduction vapourizers is whether the load is constantly heated. This is the Achilles' Heel of many conduction designs like the Pax, the Flowermate, the Ascent, and the Indica to name a few. They're affected to different degrees but all of them suffer from flavour degradation due to constant cooking. Although the Solo is primarily convection, if you don't remove the stem between hits then there is enough conduction to affect the taste. The FlashVAPE (conduction mode) and the MFLB only heat up when you are hitting the device and don't have this problem.

I wonder how it would work if the heat was turned way up? What you describe is known in coffee-roasting circles as fluid-bed roasting, it's preferable to drum roasting because the beans are suspended in hot air.

If it worked, it would certainly eliminate the need for stirring between hits :tup:

Fluid-bed roasting, now that is some thing I would like to see in a vape. It takes my recent DST to new levels.:\

nah its coupled with high air ratios as lwien said. fluid bed roasting is for roasting and not for concentrated vapor production.

imo to create the densest hit one would need a large surface, that heats fast and transmits the heat fast and without dilution of air to the plant matter, basically conduction on large surface areas. but this would also spend the green very fast and taste wise i dont think it would be superior to anything.

I dont know about high air ratios but air turbulance in a sealed heating chamber with the product being tumbled at set temps would allow any cannaboids to be suspended in a vapor form until extracted by standard convection methods.

ok that is actually a very good input, maybe a little harder to accomplish but yes that could work well!


:)

OK just bringing some relevant chatter to the thread.

Taking my thoughts a little further.
I was watching a concrete truck this morning and the agitator got me thinking. The way the concrete moves in the agitator during loading, transport and unloading.

WTF you may ask.

Picture this.
A household appliance similar look and size to a standard toaster.
Basically what you have is a small fan forced oven chamber with a scaled down agitator that would be perforated similar to a colander so air could flow through it.
The unit would be loaded similar to the concrete truck. The product would be dropped down the chute into the agitator/oven which would have been pre heated. As the product is rotated in the heated agitator, it heats and breaks apart constantly releasing fresh cannaboids as fresh material is exposed. At this stage the air in the oven should be saturated with resins and cannaboids in vapor form ready for removal.
At this stage I would see it with a gong whip attachment for standard convection use and a second removal port where the unused vapor would be cooled and saved as pure decarbed oil ready consumption.
To unload spent herb put the agitator in reverse and it dumps the spent ABV out of another chute.

Any thoughts
