Here it is.. This is the cheaper brand that comes with a free floater and a free replacement disc.

Anyway, so far it seems totally sweet. I have a DWC and now i'm able to have the water level at a fraction of what it was before.. A far as i can tell everything is rolling smooth...I check it out every few hours to make sure my roots havent went to hell but so far so good! Roots appear to be covered in a fine mist.

Anyway i'll update over the next couple weeks, i'm flowering some auto-aks (about half-way to hvst) so i'll keep an eye on those roots and tell ya what i think if my 38 dollar fog investment

 

[micro gro]

Not sure it'll work. But I'll keep an eye on this thread just in case.

 

[punx777]

thx for the optimism

 

[micro gro]

Only being realistic seeing how others have fared. Hope it works though.

It will work, Good way to enhance ur DWC

 

[punx777]

thanx alot norcal i'm watchin some trailerpark boys right now


... everything seems to be goin amazin so far i only have 3 or 4 inchs of water so the mass of the roots stays suspended in the fog. should be fun! i can't think of a way thatll get more air to the roots

Do you guys think is till need the air stone in the water?

I would put an airstone but that's just an opinion that i can't back up w/ fact. Couldn't do any harm.

Don't listen to the naysayers --- you're on to a great addition. Please keep updating. I'd like to follow your progress.

I would at least let some of the bottom of the root touch the water just in case, you never know with hydro things can change so fast, you might want to keep a really close eye on it Id hate something to happened just because its not well documented but i think you can benefit from more than one way to bring nutrients to the roots.

 

[Standaman]

I would say 2 airstones in DWC at the very least mate.
For me its all about bubbles or you wont yield as well as you can. Put some pics up of your room to give us an idea

If the high ppm nutrient fog comes up thru your netpots, it may burn your bottom leaves. And this plant is so adaptable/finicky that it grows roots specific to the medium its in.

 

[punx777]

I was concerned that fog would escape and cause problems but its not like that at all.. the only time fog escapes. as far as i can tell it don't escape thru the net pots....... and its not by any means like dripping wet from humidity inside the resivour..... the netpots are slightly moist.

my best plant startin showing trichrome stocks growin on some leaves, and the plants seems 100% healthy.

Nice to see someone trying to use fog, it is the way to go. Having used and played with "pond foggers" here's a few things to keep in mind.

The fog produced has a tendency to stay low and wants to stay on the water surface, it does not rise up to fill the resevoir without some sort of assist, like a small fan.
The transducers (discs) tend to run very hot, any tap roots that come in contact with it will be burned. It also might up the temps of your solution, so keep an eye out for that.
Even the teflon coated discs build up salts and crap from your nutrients and will need constant looking after and cleaning. The best nutrient I found for the use with a pond fogger is Humbolts, it has much less build up then anything else I've tried. (DM advance is a close 2nd)

Not too long ago I built a 5gal "bucket of fog" using a 5 head pond fogger, with a fan and hose outlet that fed into a 3'x3' aeroponic grow tray, now an aero/fog-ponic grow tray. Works good with good results.

Good luck with it, it is a worthwhile experiment you are doing and I think you are headed in the right direction.

The 'realistic' guy above was only saying that the ceramic disks burn out easy,and the consensus is that they do ,but i'm interested none-the-less and i'd suggest that you change disks every 2 weeks or so,or is that too careful?
Tell us your take on it.

[punx777]

sounds like way too often, they should last months

 

[Carboy]

When Oldmac was referring to using a small fan:
You want it blowing DOWN, which is counter intuitive ---- you'd think you'd want it pulling up. Not the case. Use something like a computer fan and if you can control the speed all the better, but not required. By blowing down, it creates a sort of vortex and the fog circulates thru out the inside. I'm talking about all this in relation to a container like a regular Roughneck and the like. Also as Oldmac says ---- keep an eye on the rez temp.

[punx777]

res temp has been a pretty consistant uh, cool-to-the-touch degrees celcius . I don't have a fan yet but it sounds like a good investment.... unfortunatly i dont have room on my power strip for another brick dc adapter... any suggestions?




Regardless new root growth looks amazing.... white and lovely.

So far so good then.
I might try this setup,but a chiller in a bucket grow and adjust the temp accordingly since the Neb. will heat the water a bit.

 

[punx777]

if you can afford a chiller go ahead but my single head puts off hardly any heat at all...
in my 15 gallon res i have probably only 3 or 4 gallons and i assure you the water temp is barely above ambient, if at all......


If you can afford it i would look into a nebulizer with 2 or more heads, I would assume that this would give you a denser fog

perhaps finding a setup that has a smaller volume resivour would be better

a fan to move the fog around would be a good addition.

 

[tmu]

Definitely look into using air stones, the more the better. They'll cool the solution and keep it churning. Do use the teflon discs. Ordinary discs ware out really fast! Oh, and you don't want any moisture building up on the roots. Kinda defeats the purpose...

 

[punx777]

i turned my airstone off.. I'll tell ya if things get worse ill tell ya.. i dont think its too important as the majority of the roots are sitting in air....

Why no moisture building on the roots? They have a gentle dew on them and everything seems fine. thx tho.
