'afternoon, Voltizenatics.

If you went looking for worms here, Ducky, you'd need an ice pick! We had early May weather during the week and now we're back to February. It was 12 when I got up this morning, too $(&%@^ cold for my tastes! We've even had some snow squalls and flurries. Further north, in PA, it was so bad there was a 30 car pile up on an Interstate from one of them. Visibility dropped to zero according to those involved. We had a coating on the grass, which happened in about ten minutes, but it evaporated by morning.

Other than that, nothing much going on. I am, probably, going to make the plunge and buy a chipper/shredder. I hate spending that much money, but the constant accumulation of branches, twigs and leaves is getting to be a pain. On the "leeward" side of the house there's a drift of leaves about two feet deep, thirty feet long and about ten feet wide. The mower can pick it up, but that's a lot of work for the mower that it isn't really designed for. Raking, bagging, dragging it to the curb and then only on the first week of the month. I've looked at a bunch and all but a few are made in China and the reviews vary widely, especially concerning quality and durability. I guess it'll be a DR, made in Vermont.

We had a cold week along with a few flurries this past week as well. It was in the teens last night and the night before here. Today it was around 60 degrees here though! The next couple of days it is supposed to be in the 60s, but rainy.
I live pretty much surrounded by trees, and I feel your pain with leaf pile ups. They get frustrating, because I have to rake them and bag them so many times it just gets old. I have to rake my big flower bed out again due to the high winds from last week, and the springs washed down a ton of leaves from the woods into my two ponds. It is so full again, and it is heavy leaves, sand, pine needles, rocks, and branches. It will take me a few days each to get them cleaned out. We got quite a bit of rain last week. The springs were roaring.

'moanin, Volties.

There's a major discussion going on over in the "Evolving Thread" regarding the safety of vaping at various temperatures and I think that everyone should be aware of it.

There was a major conference, National Academy of Sciences, Engineering and Medicine, at which Evolv released some interesting data that they have been collecting. The way the software works for the DNA series of boards allows, at the users discretion, reporting of use data of each board. The end result is about 180,000 users reporting real life use data regarding temperature and puff duration among many other parameters. This is a much larger pool of data, and since it is generated by "real life" vaping rather than controlled lab experiments and is probably far more representative of what is actually happening when you hit that "fire" button, than has been available before.

To give a quick summary, at least as I see the data and verbal summaries, using TC mods is a critical factor and keeping the coil temperature below about 440F is the key. This applies to both tootle puffers and cloud chasers. At temperatures above that 440F mark the production of formaldehyde and acetyldehyde both increase dramatically and can easily exceed the amount produced by a tobacco cigarette. Another interesting point is that larger tanks and coils generally result in lower and more consistent coil temperatures. Food for thought for all of us.

In fact, chain vaping a stock tootle puff setup can easily result in temperatures that increase well above that 440F mark in as few as five puffs. The CE4 style atomizer has been shown to produce very high levels of aldehydes just in normal use because the temperature of the coil rapidly passes 500F and above. There are a number of factors that produce these problems, like thermal mass, air flow, coil diameter, wick efficiency and so on, but the bottom line is that the CE4 is not really a very good atomizer in terms of safety according to the information I've seen.

If you want to look at the data go over to the "Evolving Thread" and it's on the last three pages or so. I know this is the SI thread, but this information does seem rather important and relates to the safety of every vaping device.

A new thread on this subject has started up. New studies find carcinogens in vg and pg at high temps, even in tootle puffers

Interesting, I like mine not to be too hot and I even vape from two Provaris if I am vaping a lot. I think that we should all be aware of these sorts of things. Thanks for sharing.

No wind right now but they are threatening us with high winds later.

I'm thinking about how I want to design my back area for summer time usage for the horses. They need shade at the very least!

Lizzie, you're missing the point. Perceived temperature at the drip tip can be vastly lower than what is going on at the coil and even as little as 100F, at the coil, can be the difference between high aldehyde exposure and no aldehyde exposure. Low power does not insure low aldehyde production in any way, and it can be illustrated that low power can actually result in higher aldehyde production than higher powers...temperature, not power, rules. I know this seems to fly in the face of what we've all experienced, but the science behind it makes it pretty obvious that is the case. Given that the results are from a pool of 180,000 vapers during "normal" vaping and not in a lab makes it even more significant, to me anyway. And to think, I used cartos and CE3s at "low power" for a long time. I do wonder what conditions actually were at the coil in them.

So, lower temps is worse?

No, lower temp is not worse but tootle puffing, especially with higher resistance small coils, can be much worse and worse yet if chain vaped. It has to do with how hot the coil gets. From the information presented it can be extrapolated that a large diameter coil of heavier gauge wire running at 50 watts or higher is actually safer than a small coil running at 7 watts. The temperature of the coil is the key factor and that large coil, with those giant wicks, will actually run cooler due to the evaporative effect of the large liquid supply and the much larger amount of air flow when compared to that small coil with a tiny wick, low liquid supply, and relatively low air flow.

Unless you're using a TC mod there is no real way currently available to determine the coil temperature. The mods that claim TC on kanthal are not actually measuring temperature and have to be set to a reference, by the user, based on how the vape tastes nd then they regulate power based off that "reference"...anything but accurate. Even with TC wire, like nickel, titanium and stainless, the actual coil temperature may not be all that accurate, but it is far more accurate than a guess based on how something tastes and there is no way to determine coil temperature based on power, voltage/resistance/current.

This is a graph of temperature at low power, call it a typical entry level setup, with about a three second puff taken every 30 seconds. Notice how the temperature increases with each successive puff and is well above the 440F level. Aldehyde production begins to spike, dramatically, at 480F.

I don't even know what tootle puffing is. I just do the cartos with a tank.

A cartotanker??? I thought it was difficult to get cartos anymore. Never was successful with them. Kicked nemmy with kayfun for me, I thought I was old-school.

I love my carto tanks. I have about 150 cartos stashed away. I won't have to change until I use them up.

A "tootle puffer" is a vaper who uses cartomizers, clearos, or tanks with replaceable "stock", ~2 ohm coils, vapes at anything from five to fifteen watts and uses the mouth-to-lung method. Because of the small coil, a resulting small thermal mass (way to dissipate heat) allow it to heat very rapidly and the relatively low air and liquid flow (cooling components) the coil temperature can easily pass the 470F mark where aldehyde production starts to spike quite high.

I will say that this is based on two different studies. One studied the aldehyde production of PG/VG when heated. That study did not involve vaping gear but was conducted simply by heating the liquid and was also conducted by a State Agency in California which does add some questions regarding its veracity. Other studies I've seen around do seem to support this though and I wish I could remember wher I saw them and cite them.

The second study showing that rapid temperature increase in smaller, "traditional" style atomizers, was done by Evlov and actually was collected from a large pool of real user data. Incidentally, because VG has a lower boiling point, high VG liquids are more prone to aldehyde production when overheated.

There are multiple schools of thought regarding exactly how these studies can be correlated, or if they can be correlated at all, and if that heating/aldehyde study applies to vaping since it didn't involve vaping gear. From my viewpoint I do think they can be correlated and even if they can't be, there does seem to be a definite hazard from overheating liquids used for vaping. We've all had a "hot" or "dry" hit and know what that's like. Those unpleasant results are a result of undesirable chemicals being produced, like aldehydes and ketones. The problem is that those chemicals can also be produced and the user may, or may NOT, be able to "taste" them. In other words, even if your vape seems fine, you could easily be overheating the liquid and be exposed to higher levels of potentially harmful byproducts. Since those seem to be a direct result of temperature knowing the temperature with some degree of accuracy seems to be quite important.

Saying "I only vape at seven watts so that should be safe" is not really true. Due to the low air and liquid flows, small wire size and a host of other little variables, temperatures can easily exceed safe levels. Unless you can measure the temperature of the coil, somehow, you simply cannot know.

So people should watch out for creating high temps. I don't think I vape in watts. I like my Provari at around 4 to 4.5 whatevers. :) I forget all that stuff since I use the same system for 4 years now.

I'm just happy I quit smoking and still feel that my life is fulfilled due to vaping :)

It is a beautiful day here in Northern Nevada. I'm sure I need to work with my horse and do outside jobs.

The bottom line is if the wicks stay wet you SHOULD be OK, Lizzie. The biggest thing is to be tobacco free. While some chemicals may rise above the levels of a tobacco cigarette, there's still a few thousand, nasty ones, missing in vapor.

We had a nice day yesterday and it's warm, but windy, today. I just saw a Township truck with a snowplow on it, anticipating tomorrow's snow and the potential snowstorm on Tuesday. If you don't like the weather where you're at, just wait until tomorrow.

'moanin and groanin, Volties.

It was almost 68 here yesterday. Right now we have about two inches of snow and it's 32 outside, been dropping since sundown yesterday. The roads are clear, way too warm for snow to stick, but the trees and grass are covered. It does look kind of pretty and we may get a lot more "prettiness" on Tuesday, maybe as much as eight inches. Winter seems to be trying to make a come back, but it won't win.

We got a new ball for Leo, one he can't get completely into his mouth. He has a lot of fun chasing it, then chewing on it, then chasing it again. We're hoping it'll hold up for more than just a day or two.
