Good information thank you! I am using a rubi pod system for convenience at work. I think it’s around 8.5 watts. Is that a good range for preventing spitback?
Honestly, I have no idea. Wattage is only 1 part of the whole picture. Wire gauge, length, wicking, airflow, and airway, also influence performance. And, I am unfamiliar with that device.
I will say, generally speaking; that e-liquid recipes can often be adjusted to perform better in most devices. Whether it is increasing/decreasing flavor percentages, or adjusting viscosity, there is often something that can be done... even in fixed power/build/airflow devices.
They have also claimed to have fixed that problem with their pod designs.
It is certainly possible. I have seen all sorts of designs, trying to keep e-liquid out of the vaper's mouth. Screens, diverters, indirect airways, and on and on. Some, quite successfully.
Do you think less than 10% dilution will cause clogging? I’ve had pretty good luck with these pods. They are kind of expensive and are only available online (i didnt do enough homework) and from the reviews i’ve seen they recommend 3 refills per pod but i’ve gotten at least 7 refills before i start tasting burnt cotton.
As I said in my previous post: Some vendors already add a bit of water to "100%" VG mixtures, specifically to help thin it out a bit. If I were in your shoes, I would start with a straight mix, without any additional water. and then (only if needed) begin incrementally adding water (maybe in 2% increments?).
(Note: Because water is neither PG, nor VG, it does not technically effect the PG/VG ratio. A vendor can honestly sell a "100% VG e-liquid," that contains water, and not be lying.)
I respect, that the cartridges are expensive, and you don't want to needlessly waste them. Again, if it were me, I would use an older pod... one you have already gotten some mileage out of... but is still functioning. It might make a "fatality" a bit easier to accept.
I also question if a "clog" is a true fatality. Both PG and VG are water soluble. If you start getting dry hits; stop vaping on it,
before you scorch the cotton, or burn through the wire. Just remove it from the device, rinse it out thoroughly with tap water, and give it a day to dry. Then you should likely(?) be able to use it again.
Water won't help with burnt-on coil crud (unless you have the means to dry burn and re-wick it). But, it
should be able to help with a moderately gummy wick.
If i pull too hard on it that will happen though.
I am assuming you mean the spitting/juice in mouth? Then, yes; taking too hard of a draw, is certainly a good way to have this happen. When one is vaping on a non-adjustable airflow device; one has to adapt their vaping draw to accommodate the device.
Also, I would expect further thinning the e-liquid (by adding water), would only make the problem worse. Spitback is a problem caused by too much liquid, not too little.
If you are referring to dry hits; that is more about the wicking, than the draw. wicking brings the liquid into contact/proximity of the coil, which in turn, converts the liquid to vapor. The wick is the primary influence here (and, indeed, thinning the liquid helps wicking). Draw is a secondary influence. It does create a bit of a vacuum, which can accelerate the wicking action... but, only to a degree.
If you are dependent on strong draws, to get adequate wicking; you either need a thinner liquid, or you are vaping the wrong devise (for your vaping style).
Remember that many pics, like the Juul styled ones (including your Rubi), are designed for very tight MTL draws, and low vapor production. There are others, like the Aspire Spryte, that offer adjustable airflow; which can offer something more akin to a restricted direct lung hit. Choose what fits your style best.
It’ll probably be a bunch of trial and error making many 30ml sample batches until i find the formula for me.
30mL samples? That is 30 fills of the Rubi's 1mL pod. To figure out what the best viscosity; I would think that even as little as 0.5mL would be plenty to see how it is going to flow.
I know that mixing ultra small testers can be a pain it the keister; especially when adding low percentage flavors. So, go only large enough to make mixing tolerable. I would probably be considering 2-5mL (tops).
Of course, all of this, are just my opinions (based on personal experience, and my own research). You, and/or others, may have different ones. Do what works best for you.
