I knew this was very likely asked before but only found a very long flamewar threads about homemade fog fluids and safety.
I just swapped my 1500W chinese fogger with a 1800W german one. Don't expect much difference and 1500W already produced plenty of fog indoors for large rooms and even auditoriums without extreme ventilation syste,s although needed to wait for it to reheat and generate fog several times.
Now I'm building 3 10W projectors and need something appopriate for them. I think for the same size venues as before 1800W fogger should still suffice if it was enough for 1.2W before.
But while I'm at it swapping old stuff and upgrading I'm thinking of trying ot hazers.
Two things come to my mind about which I'm completely clueless.
One is how hazer power in Watts is chosen for given area size. I have gotten the same info I needed with the foggers but it was by trial and error, some mediocre shows while I was learning because of poor knowledge and I was fortunte enough that the 1500W I had gotten was sufficient for all my work.
I don't want to end up the same way with hazers this time as a) this time around I might not be as lucky and end up buying an underpowered hazer which aren't that cheap anyway and b) I have certain reputation now and don't want to ruin it by looking like an amateur again who is still learning his equipment. So this is how and why you can help me here.
No I don't have a big enough testing environment to learn all this by trial and error outside of shows.
When it comes to outdoors I don't have experience with foggers as well so any tips on creating an atmosphere outdoors less likely to dissipate very quickly will be greatly appreciated.
