I'm pissed by Arizer's dismissive response to my "cloudy tube" inquiry. To recapitulate, both new stems from my Solo II cloud-stain on first draw. Anybody who has experienced this with a new Arizer stem (I or II) please speak up and post pics since I haven't replied to Arizer yet. Here's a picture of my tube and Arizer's snotty response.
Thank you for your email.
Residues can form on the inside of the Glass Aroma Tubes for a number of different reasons, such as the moisture content in the materials, the type and quality of materials used, the humidity in the environment, temperature settings used, among others. Also, sometimes after cleaning the glass, the cleaning solutions used and even the water used for rinsing can leave behind a clear / invisible layer that vapor can stick to.
Due to the many variables that might be causing this foggy appearance in your Glass Aroma Tubes it is difficult for me to say for sure why you've noticed this is happening. One thing I can suggest are to try using some different types or qualities of materials to see if that make a difference. Also, a tip for cleaning that could also help -- after soaking the glass in Isopropyl alcohol and rinsing with hot water, try soaking the glass in white vinegar for a couple hours and then rinse again with hot water. This extra vinegar soak may help clean any remaining residues which could potentially prevent the foggy or milky appearance.
I hope this helps. If you have any further questions please feel free to ask.
Best Regards,

Pappy... I love you man, you know this...
But that's kinda normal and what Arizer told you is the truth, they're not trying to be dicks about it. I have had this happen a LOT of times. 99% of the time it ends up being the moisture content in the herb. The Solo seems to have that sweet spot temperature/power of the oven combined with the totally exposed clear glass airpath. I have had herb straight from a dispensary that had a high moisture content and it caused my stems to fog up like this. Vaporizing will start from the bottom up, terpenes evaporating anywhere from double-digit and water evaporating at 200 degrees. The good shit is higher up, 300+ and won't start turning into vapor until a significant amount of the water content is gone. Clean out your stem with some ISO alcohol and salt. Rinse thoroughly with distilled or reverse osmosis or bottled water, not tap water. Grind some herb up, leave it out for an hour or two to dry out. Ground up = more surface area = more thorough evaporation.

@OF said, it could also be you leaving a little thin layer of ISO alcohol. You know, I noticed a really weird thing years ago when I was making ISO hash oil. If you introduced water to it by accident, or when it was drying out and you didn't use 99% ISO (and thus had a higher water content), during the evaporation process I would see a thin bright white film develop on the glass. The first few times I was confused, thinking I had messed up, but later found out it was the interaction between the ISO, the terpenes, and the water that would make it go like that. I never saw that white powdery kind of thing the few times I did BHO? Anyways I believe it was the terps + ISO + water like I said.
I see this happen a lot with clean stems too, as they get a layer of the condensed vapor it stops looking so obvious. But if you keep hitting it when it gets like that, you should start to notice it clearing up from the closest part of the oven on upwards. By the end (or well before depending on your temp), it will be all clear again. If it's what I think it is (water moisture) it should also kinda "slide" if you rub a toothpick or a poking tool around the inside as if you were scraping the reclaim.
I saw the exact same clouding phenomenon in my glass VapCap. You can see the condenser at the right angle (or if you attach it to a glass piece or some tubing) and if it's got high moisture content it fogs up as well.
I gotta side with Kevin on this one. This likely happens with all other vaporizers, except not all other vaporizers have exposed clear vapor paths like the Arizer portables, VapCap OG, etc. I've even seen it happen with my LSV wands before. Only thing is the LSV is a real powerhouse that delivers consistent heat on a different level than the Solo does, so it clears up a lot quicker.
Clean her up, dry some ground up good good, and see if it happens again. It might, and it might end up only being a tiny bit at the bottom inch of the stem closest to the heater, and it might go away pretty quickly too. I can't really think of any reason that it would be some sort of manufacturing failure with the stems. I doubt the've changed their technique such that it happens with newer stems. They're making a lot of these things in their glassblowing molds to (if not just taking regular tubing and stretching it out on one end) and it has to be consistent. I wouldn't call it user error either, though. My money's on the flower moisture content
