Are The House of Hydro's Mist Makers the same as other Mist Makers?
Absolutely not! Aside from superior customer service, our mist makers have many upgraded components. The quickest way to tell them apart is the red power indicator light on the silver head. The HOH doesn't have ANY led's. They just leak and cause failure, as well as promote algae growth. Check out our feedback on eBay, or any forum about growing, or humidification. I did a little search, and here are some links to people talking about our mist makers.

What size Mist Maker do I need for my greenhouse or grow room?
This is our most common question... and this is the response you'll get from us when you email. If you still need help choosing a size, please email us after reading through this carefully... When emailing, let me know you read this, and include the size of your room, what the room is made out of (drywall, cement, plastic), air exchange level, ambient humidity, target humidity
Choosing the right size Mist Maker depends on a few different things:
ambient humidity, target humidity, air exchange, and the type of material your room is constructed of all plays a part.
A lower ambient humidity will increase the need for more discs, as well as a higher target humidity. The amount of air exchange you have will play the biggest part in deciding which size you need. If you are constantly bringing in new air, you have to work much harder to bring up the humidity. Rooms constructed of concrete tend to absorb moisture for quite some time before leveling out. This can increase your need for a bigger Mist Maker as well.
With low/no air exchange, a smaller unit can be used. It may take longer to reach your target humidity level, but as long as drier areas not being introduced to the room, a smaller unit will suffice.
With that said, I typically recommend a larger unit such as a 6 to 12 disc Mist Maker for larger area's like shipping containers and green houses. It is better to have a capable unit that runs much less, than a inadequate unit that has to run 24/7. Mist Maker's can heat the water that they are operating in, and heat can damage electronics. Very long run times in small amounts of water can push the max operating water temperature of 105°F. It's better to have a unit that runs for an hour on/hour off than 8 on, one off.
For example, in a 4x6' growing tent with no/low air exchange, I'd probably use a single disc mister to achieve up to 100% humidity.
A 10x10 room with high air exchange, a/c, and lighting would probably need a 6 disc unit at least, but could use a 12 disc as well, it just won't at 100%.
A 40' shipping container with low/ moderate air exchange would probably need a 12 disc, or two 6 disc units.
If my projects life depended on the humidity, I'd use two units running at half the time. That way you have some redundancy in case of a problem
There are so many variables that it's hard to actually say with certainty what you need. Most online charts don't take 90% of the factors into account. Hence why so many of my customers have already purchased, and came up short on the store bought units.
How do I control my output/ what all do I need to buy?
The normal kit alone will get you started, but there are different options for controlling the output of your Mist Maker.
We offer fog output controllers to turn the fog level up and down, as well as humidistats. Humidistats will automatically control your humidity within 3% of your target level. The machine automatically turns The Mist Maker's power on and off when needed.
For most humidification projects, it is recommended that you use our 120 mm, fully encased, waterproof fan in order to efficiently push the fog out into the room. Our smaller 80 mm fan is geared towards small applications like tanks, and grow tents.

How long can I run a mist maker?
Max recommended run time is 8 hours on, 1 hour off. However the run time is largely dependant on the water temperature. 105F is the max water temp. You need to keep it under this temperature, whether it is through shorter run times, or more water in the container that it is running in. For example, if you put a 12 disc water fogger in 100 gallons of water, you could run it 24/7, but if you put it in 5 gallons of water, you would need to shorten the run time to probably 2 hours, or risk exceeding the max temp which will shorten the lifespan dramatically.
How does a Ultrasonic Mist Maker work?
House of Hydro ultrasonic water foggers use high output ceramic discs, not the slow speed metal discs that collect buildup. The ceramic discs vibrate at an ultrasonic frequency to silently create microscopic (< 5 micron) water droplets. Ultrasonic humidifiers make a cool fog that is great for reptiles, greenhouses, and home humidification. Mist Makers use a piezoelectric transducer for a high frequency mechanical oscillation just below the surface of the water. This vibration creates a very fine, very dry fog that is instantly evaporated into the air. Water foggers do not use dry ice, fog liquid, heat, chemicals.
Are Mist Makers safe?
Yes, they can be placed just about anywhere. The fog is dry so it can be used around electrical appliances and animals.
Do not touch the discs while the unit is in operation. The ultrasonic vibrations from the fogger hurt! Touching the disc while it's running will feel almost like a shock or burn that you can feel all the way to the bone. I know, I've tried.

How do I make a home, or greenhouse humidifier?
Check out our instructables article http://www.instructables.com/id/Make-a-humidifier-for-your-home-or-greenhouse-that/
Will Mist Makers carry fertilizer, insecticides, or anti-fungals in the Fog?
Water droplets from a Mist Maker will carry anything that the water contains, unlike the humidifiers that heat the water. Minerals, nutrients, anti-fungals and even insecticide from the reservoir will be carried in the fog. This allows for excellent results while using a mist maker for fogponics, greenhouse humidification and sterilization or treating with insecticides. How can you argue with these results!
How do I use "heavy" oil's/ additives with a mist maker?
You can use many different oils with a mist maker. These oils can increase surface tension of the water and reduce the output. To help correct this, you can use a plant safe product called Coco-Wet to greatly improve performance.

How much water does my Mist Maker need to run?
There is a rubber black piece on the pond fogger that is a low-water sensor. This must be almost completely submerged to operate. The optimum operating depth is between 60 ml and 80 ml. The pond fogger must be kept near the surface of the water for proper operation. The included float will help keep the Mist Maker at the proper level.
How do I clean Mist Makers discs?
Here is how to properly maintain your mist makers discs:
Take the disc key that you received free with your order with the replacement discs.
Unscrew the silver retaining rings.
Remove the white disc by popping it out with a soft instrument.
Soak the discs in a small jar of white vinegar for a few hours and then wipe them clean!

How long do the mist maker discs last?
The factory life span of Mist Maker discs is approximately 5,000 hours. This can be reduced or improved based on your water quality, and whether or not you maintain your Mist Maker by cleaning the discs.
Can I use Aromatherapy Oils with a Cool Mist Humidifier?
Yes, you can use aromatherapy oils with your Mist Maker. Use the oil sparingly to release the fragrance into your home.
Why does my Mist Maker have reduced fog output?
A reduction in fog output is usually caused by a build up on the discs. Our ceramic discs with Teflon coating will help solve this problem. They greatly reduce the build up and clean easily. If you have reduced output from your fogger, buy new ceramic/ teflon discs here, or clean them using the steps given above in the question - How do I clean the Mist Makers discs?
Why can't I use the cheap LED mist makers?

I stumbled across this pic today. Aside from having the low output 16mm disc, the Led's are causing algae growth in the nutrient water due to all the light. This will cause a myriad of problems with a hydroponic grow.
Are Mist Makers safe for fish tanks?
Absolutely!
Ultrasonic pond foggers can be used safely in aquariums with fish and other creatures. The smaller units do not raise water temps at all and create a mist on the top of your fish tank. We have a local distributor that owns a huge pet store. He uses water foggers in all his open top aquariums with no problems. One Heads and Three Head mist makers work best for fish tanks.

Can I use a mist maker like a reptifogger?

Yes! The humidity created by a Mist Maker is great for reptiles. You can make your own reptifogger with a small container and a fan. You can also just use gravity to drop the mist into the tank. It's that easy!
Can Mist Makers clean the air in your home?
Yes! The mist produced by the water fogger is negatively charged. Dust an allergens in the air are positively charged. The two particles bind together and become heavy enough to fall to the floor where they can be easily vacuumed up! I have a customer that has a large petstore... with puppies using shredded newspaper for bedding. It makes a ton of dust that lingers in the air, and causes the place to stink. He has a 12 disk mist maker with a 120mm Hydro Flow Fan that does the trick!
Are these Mist Makers the same technology as Nutramist?
Yes, the mist makers we sell use the same technology that is used in a Nutramist cyclone.
How do I make my own Nutramist for fogponics?
Making your own Nutramist unit is easy:
Find an airtight container such as a five gallon bucket.
Drill a hole for a micro-waterproof fan and a hole for your output hose.
You can make a separate nutrient reservoir by connecting an external 5 gallon bucket via a mini float that keeps the main units water level at the correct level.

What size mist maker do I need to grow with fogponics? How do I grow with fog?
One head mist makers are incredible for cloning, but not for full term growth. You can use smaller units to supplement another growing technique such as drip feed, NFT, or Shallow DWC. You will need a 3 head at least for a 5gal bucket grow, bigger is always better if your growing full term with fog.
You also don't want to put the mist maker into the container with plant, the roots will interfere with the water fogger. The mist maker also warms the water a little which isn't good. You can pipe it in with the Fogponics machine that I make on youtube.
You do need to cycle the unit, and can just use a simple timer for hydroponics. You also might need a mist output controller, or reservoir water level float to automatically keep your water tank full automatically. They are available on my mist maker accessories page.
Using the 80mm fan, turn the fan speed down as low as possible. Too much air dilutes the fog, and drys out your roots.

Can I use a mist maker for raising humidity in a greenhouse?
Yes! The dry fog produced by mist makers is perfect for greenhouse humidification. A huge portion of my customers are growing Orchids. They love the units, as they don't soak the plants or equipment and cause mold growth!
Do you have a different style plug for the 230V units?
We sell mist makers worldwide! Some of the most popular countries buying our mist makers are the UK, New Zealand, Australia, and the Netherlands. Our 230V mist makers have the two round pins for a plug. This common configuration fits almost all universal travel adapters that are readily available on Amazon. You just need to purchase a travel adapter to make it fit your countries plug.
