*If only those floggers where dependable. The Piezo disc only has a 1250 hour rated life span. Fish aquarium Bubbles are rated for 15 years life-span and I have one that 45 years old and still working. *
I purchased one recently also from ebay/Hong Kong for my mushroom chamber. It's in a 5 gallon bucket floating on foam with a net pot in the middle. They don't last forever but the expensive part is the power supply and you can buy them separately.
I cobbled my power supply together from 2x12VAC transformers that I salvaged from old powersupplies - as there's no electronics involved (just wirewound transformers) that particular supply is likely to last forever.
Jim, did you encountered problems with excess heat produced by the transducer? I've recently transplanted the seedlings to the mist chmaber, but after 24h the temperature of the tank have risen above 30-some degrees so i'm realy afraid of the roots wellbeing(i'm considering plugging the watercooling into the system, so most of it would dissipate on huge radiator). Second guestion is did your fogger worked 24h, or did you sequenced it somehow? Regards, Jack
Do you have a model # of the mister you bought? Or an example of 1 like it? I see you did an update recently. How long have you misters lasted? Do you see any signs of the mister not working as well as in the beginning? Also if one was to buy a power supply you said it was a 24v is that right? Do you have an example of that? Sorry to ask so many questions. Thanks for your time :)
Hi Benja. The mister is a Jkeer WHT-35A (Otherwise known as the cheapest mister I could find on ebay... www.ebay.co.uk/itm/Ultrasonic-Fog-Mist-Maker-Fogger-Water-Fountain-Pond-/121214336802?pt=UK_Pet_Supplies_Fish&hash=item1c38efff22 ). They do seem to wear out pretty quickly. The first one I had lasted a couple of months and the second didn't even last as long as that, but they're cheap enough that I can consider them to be a consumable item, so I've got another 5 of them on order at the moment. I don't have a model number for the power supply as I did a DIY job building that, but pretty much any 24V AC or DC supply will work. These little misters only use about 10W of power (0.4 Amp). If you've got an old Apple Laptop power supply kicking around, I believe that'll be 24V. Hope that helps. Cheers!!
Jim Conner Thank you so much for the info :) and getting back to me so quick. I know just enough about electricity to be dangerous to myself :) so im always trying to check and double check things before i jump in with both feet :) I enjoy your videos on DIY electronic and the stuff you build but i watch for your garden :) Thank you for your time i will have to try to build one of these one day for sure :)
It's great for starting plants off, but I've found that after a few weeks the nutrient salts accumulate on the ultrasonic transducer and cause it an early death, so I wouldn't recommend using it for the entire lifecycle of the plants. I generally start of seedlings and cutting in the fog, and then switch them to DWC as they get bigger... DWC has one massive advantage for me which makes up for the higher water usage... If all the electrics fail, the plants still have access to a water supply which will keep them going for several days. Cheers!!
Aquarium airstones don't provide 50 micron droplets that are instantly available to the roots. That's the main reason these misters work is their immediate availability to the roots systems at the precise size for use.
I'd like to see the research paper on 50 micron's. Seems like a gimick, leafy greens will grow in a huge variety of conditions. I recommended air stones because i've grown peppers, tomatos, chard, etc... by having an airstone splash the root zone. It's a plant, not a military spec CNC milling requirement.
Hi Akram - I would say no to that... Not that the nutes going anaerobic has ever been any kind of a problem. I'm only using it for rooting rather than for long term growing, so the mix doesn't really have much of a chance to go bad. However, there isn't much motion in the liquid and certainly no good mechanism for getting oxygen down to the bottom, so I wouldn't recommend using this setup for the full growth cycle. Hope that helps. Cheers!!

I've got to agree with that. The foggers tend to die after a couple of months in hydroponics.

Please give us feedback about the use you have all those years . Does the device has problem from nutrients salinity?
Hi is nutrient solution can affect the ultrasonic fogger and how long does ultrasonic fogger needs to be open if the water has nutrient solution

u use that for 24hrs? combined it w/ timer n humidity sensors. ooorrrr u can combined w/ evaporated wtr or else use peltier
Set your timer for 8 seconds on, 4 minutes off or adjust as best as you can with your timer

nice vid and i loved it. Can i get the information of your foger? i was looking for the exact kind of product
I really like this idea! It sure beats deep water culture's massive water usage!

Thanks for letting me know.
Aquarium air stone works well and never had an issue with plugging up. Not as fun though as you don't get fog.

Does this fogger aerate the water enough to keep it from becoming anaerobic?

Clever, good job sir.
Wow great gadget
