Water plus glycerin is not the best mix. It works, sometimes, however.... A lot of tutorials are on the web by people who will do anything to save a Euro/Dollar/Ruble/Pound/Centavo.. Some of them find something that works, but it may not be tested for audience exposure. Fog juice is usually a mixture of food grade / fish derived glycols, related to glycerin but not the same molecule. Food grade chemicals are used because in bulk they are cheap, and yet they will be more then pure enough and consistent for good "process control".
So the fog is "cracked" when it passes through the boiler. Sort of like burning, but without the oxygen. So what you breath is the product of this chemical process. If you use the wrong stuff, long term it is hazardous. If you use the really wrong stuff, it can be very hazardous, especially if you use Ethyl or Methyl Glycols..(Antifreeze)
Most manufacturers do not disclose their exact mix, so there is a lot of bad information out there. Is it worth risking your health? Especially indoors!
30% Pharmacology grade Glycerin will work in some machines, but is not optimal for maximum, clean, nearly odorless, fog. It may have a perfume or preservative added to it, at least what my local drugstore sells, does. That perfume when "cracked" in the machine smells awful.
In most parts of the world, if you buy professional juice in bulk the pricing is not that bad. Its the "per litre" costs in small batches that are expensive.
1 LPM is a huge amount of juice. How many Watts/What model is this machine? 1 Litre in your average single car garage is a couple of days of useful fog.
