Should I get a Nutramist fogger?

"Hmmm, do you think I could wire one transformer to run 2 or more units?"

Probably, they use standard wallwarts.
And they may be shippng the same one that they ship with the fountain foggers which also support an LED display.
But if it's running that hot...
Just look on the mandatory label for the max current rating and divide by two. ;)
Then check the modules appetite.

Doubt that a small voltage drop would cause 'em to drop out of oscillation.
Don't know enough about how they work, yet, to guess if it would affect droplet size.
If so, it's a "feature". Makes 'em tunable.
Love the float.:thumbsup: Gonna steal it.

Hey oldmac, I was wondering about those root guards. Are those the round things in the photo that look like smoke detectors? I was thinking about this problem too. Do those do a good job of keeping roots out? Also you may know about something else I was wondering, does the transducer kill roots if they get too close? And if so, how close is too close?

Maybe I missed it, but did you say how often the misting nozzles would be on? Did you get a chance to think about my question regarding them washing down the roots? I was wondering if this would defeat the effects of dry fog, or maybe lessen the effects, since the roots would be getting less air.

I understand the redundancy idea. Along those lines I was thinking about frequent power outages (something about being at the end of the line), and of course I can't have my roots sitting in nothing but air for 8 hours. To solve that and other issues I thought of being able to adjust the level of the reservoir that the roots are in. I would keep only the bottom inch or 2 of roots in water at all times. There is another reservoir so that the root res can recirculate, oh I don't know, maybe for 2 minutes out of every 15. Of course there would be air stones in both, and probably a powerhead in the 2nd res. So what do you think of that redundancy idea? The large tap roots have all the nutrients they want, yet the others never get washed down and should grow to be very fine and hairy.

What did you think of my test. The container filled up pretty well, but maybe I should use 2 units in my veg res and a 3-head unit in my flower res. It would be great though if I could get away with 1 unit in veg and 2 in flower.

Anyways, I certainly appreciate you stopping by. Anything you choose to answer or talk about would be wonderful.

Thanks Weeze, maybe I see another test coming.

De nada.
I owe ya for my education.

About burning the roots.
I have a fogger in my koi pond.
When the Lilly pads float across the emitter it burns track in them.
Here's a snap of a lilly pad that got in it's way.:(
Sliced it like a laser.

Does not seem to bother the guppies.:)
Bet the little stoners are suckin' on the blue lotus rootlets.:D

Mebee try a bold experiment.
Finger dat fogger!
If you finger no like, roots no like.

Keep talkin' to yo'sef.
Lotta lurkers listnin'.:)

Thanks for that photo, and wow, I didn't realize the damage it could do. Maybe I'm a sissy but I've been reluctant to stick my finger near the transducer. People say it hurts, but what is pain anyway? Is it real? It's just electrical impulses. That can't be real horrible. Besides, pain is such a rush. It let's you know you're alive. I was certainly alive when I slid the throttle cable under my thumbnail. OK, so back to work on the weed guard for my fogger.

mmmm, Blue Lotis. Have you consumed that perfectly legal plant?

Opie;

Really nice experiment! For only a single head unit you got pretty good output. You could have saved your self some "rube goldberg" building of a float if you bought a bouy. Consider it when you go to a three head unit, get it with the bouy, it gives you automatic water depth for the transducer. Which you should change to the teflon coated ones, they do not clog up so easy.

Most builders of pond foggers, that use a resevoir, say that the fog tends "lay" on the water and most use some sort of fan to push or pull the fog to the top of the lid. I considered the use of plastic tube hooked to a vacum pump to raise it.

As to my system, and the possible wash down issue, we need to looked at what others have come up with. The Dominaero as a grow machine uses both aeroponic spiners and 3 head pond fogger for ultra-sonic fog. The Ultra Mist applied to their grow system is an Ebb & Flow with a three head ultra-sonic fog pumped in separately. No one is really using ultra-sonic fog on it's own.
I simply made my reduntant system one notch down the evolution chain to aeroponics (pressure mister system).

The pressure mister system on my machine is calculated to run 3-6 seconds (every 1/2hr). The actual time is dependent on the time it takes to pressurize the sytem after turn on. Most of these systems are set-up as "pressurized" systems and the flow to the nozzles is controlled by soleniod, where I'm using the "turn the pump on" method.

The root guards are "inlet suction spa covers" and I used them because I'm inroducing fog towards the bottom of the grow tray, plus they looked so cool.

Hey WZ,

I can't believe what the pond fogger can do to the water lillies!

Even better idea on how to test the temp of that sucka'.
That is really an issue I had not considered with pond foggers.

Those nutramist foggers are crap, I bought one for some house plants, and it worked great, till the water ran low, It has a sensor that is supposed to shut it off when this happens. However it did not and it burnt out. I boaught the cheap ones off of ebay for 15 bucks each and those still work. The nutramist was like 45 dollars and it broke ina week or so and they didnt wana exchange it or nuthin. I would say go with the cheaper versions that have replacement parts and stuff. Ebay hass em for realy cheap.....


And the foggers ocilate at sub sonic speeds that is what does the dsamage not temperature, do not stick your finger in the disk, it is irratating then hurts then painfull. Basicaly you are demoliculizing your finger so dont do it, I know some one who held his finger in ther for a long time, now he has no feeling in that finger forever..

I'm sure you meant to type supersonic.
And, the "Poke 'em witta finger", was a joke of course.
Dat sucker would emulsify your manual digit!

Was about to buy one till I read your post.
$45?! :wtf:!

But, as he said earlier. The El-cheapos droplet size exceeds 5 microns.
Above 5 microns I'd save some dough and use a mister instead.
They clog on occasion, but they don't fry.:)

For me, this is all still theory.
In practice, I just drop in 2 airstones and a small, submarine, water pump in a wastebasket.
Don't even use a mister with the Bubbaponics units.
Just jam the 1/4" water hoses in the sides of the net-pot and let 'er drip.
Works well, so far...
When I get a few jars of meds ahead, I'll work on points for style.;)

Thanks for the input, made me think.
