Snow machine? I own a few and they do not create smoke . they create a foam like substance that falls like snow. they cost about $600 CDN a pice if your woried about budget these arnt the way to go.For low lying fog you can use a Dry ice machine as well as the above mentiond methods. but your outdoors and the slightest gust of wind will unsettle your fog it will generaly not work well out doors as well your in a hot climate. and to keep the fog low to the ground it has to stay cold. but in a warm climate it will rise off the ground very quickly,dry ice is extrmly expensive. and if you want the effect to last a while you will need multiple machines. The dry ice machines we rent are about $300 a day plus dry ice which ends up being about $100 for a 10 minute effect depending on what were going for.and what i gather from your post that you are looking to save money. well i think buying a machine will not save you money on your lighting as you put it?try using what you have more effciently rent some gear insted of buying it will go farther.JH

One of the first questions we're asked by anyone interested in fog machines is "How much fog liquid do I need?" Whether you're running a low-lying swamp fog at a haunt, or a light-tracing haze in a geyser at a concert, or fogging out an escape room until no one can see each other, you need to be able to accurately predict how much fog machine fluid you're going to go through - because you never want to run out!
We're going to talk about the factors influencing fog fluid usage, how to gauge your own fog liquid consumption, and finally, we'll provide you with a table of fog machine fluid usage rates that should help you understand how much fog fluid you need for your venue, haunt, corn maze, or party!
Just like the number of miles per gallon you get with your car, multiple factors influence your rate of fog consumption - which we're measuring in "gallons per hour". Just like your car, where things like your engine, the weight of the vehicle, how much you're towing, and how you drive all influence your miles per gallon, there are a few factors to consider when determining the gallons per hour you'll use with your fog machine.
The primary thing to consider is the power and type of your fog machine. Fog machines come in different wattages, from as low as 400 watts to as high as 1800 watts or more! The wattage of a fog machine doesn't directly tell you how much fog it will generate, but it's a good approximation: the higher the wattage, the more fog it will produce.
Another factor to consider is the type of fog machine you have. A haze machine will output significantly less fog than a standard fog machine of the same wattage, and will use a lot less fog fluid. An 1,120 watt Hurricane Haze 4D will only put out 4,300 cubic feet of fog per minute (CFM), while the 1,190 watter Hurricane 1800 Flex will put out as much as 29,600 CFM! A geyser fog machine will generally use about as much as a standard fog machine - but check the table below to make sure.

You also need to take into account how you're going to use the fog machine. It's extremely unlikely that you're going to just run your fog machine for an hour straight! Firstly, fog machines aren't generally designed to run continuously, anyway, but to cycle on and off to maintain the correct heat in the coil. Second, often this would just produce far too much fog for your application. So when using our Fog Machine Usage Chart below, remember that it's measuring how much time the fog machine is actively producing fog: if you're using a Geyser P5, but only firing it for thirty seconds every minute (1/2 active time), it's going to last 80 minutes (40 minutes divided by 1/2). That formula (hours per gallon divided by active time) isn't necessarily easy to remember, so just think that if you're using it 1/6 the time, it'll last six times longer that the Hours per Gallon; if you're using it 1/4 the time, it'll last four times longer, and so on. Consider, too, the application of your fog machine. A low-lying fog machine being used in an indoor application will need less fog fluid than the same low-lying fog machine outdoors, because of the natural current of the wind. A light-ray-tracing application uses much less fog that a hyper-dense "fog 'em out" application. The last thing that influences how much fog liquid you'll need is the type of fog fluid in your fog machine. If you're using a light tracing fog like our Vanishing Point Fog Fluid, you would need to run the fog machine longer for longer to get the same density as our hyper-dense Whiteout Fog and Haze Fluid - which is one reason it's so important to choose the right type of fog fluid for your needs. There are a couple of ways to determine how much fog fluid you're going to need for a given night, week, or season. The most simple is our "4/1 Rule", which simply says, "Buy four gallons, buy more when you're down to one." But for extremely high-usage or extremely low-usage applications, that just might not be precise enough. Another way to figure out how much fog machine liquid you'll need would be to use our chart, below: find the machine that most closely matches the machine you have, and just look up the Hours Per Gallon! (Don't forget to consider your active time, described above.) Of course, the most precise way to know how much fog you're going to need is testing it. This means planning ahead a little bit, but all you have to do is buy a gallon of the type of fog machine fluid you need, and then use your fog machine exactly the way you plan to use it, and see how far that gallon goes. We like to suggest you include a little extra, to account for special conditions like wind, temperature, and user error: the last thing you want to do is run out of fog midway through the night! With a little bit of work, you can cut through the confusion of how much fog machine fluid your fog machine will use, and buy the right amount for your application. Just consider your machine's power and type, your active time and what you're doing with the fog, and of course what kind of fog fluid you're using.
