>> Are you sure the Haze doesn't have an all glass pathway inside?
From what I could work out in their promo video with the CAD design and it being in bits on the work bench; No I don't think the chamber that enables the switching between the two ovens is made out of glass.
>> it does have several temperature options.
It has 4 :- 365F, 380F, 390F and 415F , the last one is too high for herbs, if my research is correct, combustion starts @ 400F.
I am also enjoying real low temps for the first few hits, very tasty, not sure how low to go but according to this site
http://www.zamnesia.com/content/284-vaporizer-temperatures-for-cannabis
THC starts vaporising @ 315F and CBD @ 355F plus most of the Flavonoids are in that range also.
So I want something that gives me that flexibility to play with slow-roasting and savoring the flavour, just like a quality bourbon
It does seem that both the Ascent and Haze might offer the option for Hashish as well, what with the cans / glass containers, though the silicone lids sound a bit yucky. Deliberately putting plastic in the oven just sounds wrong to me?
A) your article specifically says 200 degrees dry herb CAN start to combust, not that it WILL or always does. You may also want to read this article which I found useful and actually cites a real study done using a volcano and real scientific measurements of the cannabinoids present at those temps :

I think the method by which the heat is administered may have an effect on combustion. Some people using vapes have combusted, but I have no idea what temp they were running to cause that.
B) the Haze is designed to be used with concentrates as well as flower, concentrates have a higher flash point so setting #4 (which, if you read through the best of or search the thread, you wilL see that it can actually get HOTTER than 410 depending upon which can/screen you use and the product - the magic of modern engineering!) was designed for concentrates. If you read through the haze thread and/or search the thread for words like "combustion" you can find out if anyone has experienced that, although, tmk, no one has combusted at temp setting 4 with flower. WHEN you combust, the end product will be more destroyed. The most I have heard is a Haze user with dark brown abv. I have a Haze and usually only vape 1, 2, or 3. I only use 4 when I am on the tail end of a bowl and do not want to refill, and it is bedtime because the higher temps, I understand, contain more sleep inducing cannabinoids.
I think to get those really low temps, you need either a fully adjustable temp vape, like a volcano maybe?, or possibly some convection vapes where your technique (draw style and speed) can help control temp.
As to people's reaction, you came across as being pretty certain that the word of your website is absolute truth, although i, for one, could not find the scientific citation explaining where they acquired their data. Pit your certainty against another person's differing certainty and WHAM you have true interpersonal combustion!
I do not know the "truth" behind the "best" temp at which to vape. I think it is all about experimenting and what works for YOU, which can be expensive having to try new products! Unfortunately, with its presently illegal status, it is difficult to run scientific trials, so we are left with what we have.
For you, and what you want, you should be looking at a vape with a lot of variability. Desktops probably, or at least higher end portables. Although, the magic flight box can have a range, depending upon technique...however I know people have combusted with it as well.
Was it glaucoma or cataracts that new studies had shown cannabis was NOT as useful as thought? Someone verbally corrected me not long ago, but I do not have a citation to give.
I hope you find a good vape soon! I, too, am new to this, and FC has been so helpful, except for the VAS which led me to buy an Underdog to pair with my Haze!
Edit to add : terpinoids or terpenes are what give cannabis it's odor and flavor. Changing your searches to include those terms may help. I understand your search, I am interested in a couple of terpenes as well for their possible anti-depressant qualities. I found my two favorite strains, bubba kush and headband can have nearly equal profiles of those terpenes...of course, each seed and grow will be different.

and I'm the one looking toasted
