Zardly,
Your presence is simply a must?.Namaste

LOC NAR,
Very interesting. Tryed a fog cloner and thought the heat would be a problem so we kept temps at about 70 degrees. Results were very poor. Found out we needed 80 degrees or alittle better. So heat from the pond fogger was no issue in an A/C room. More like needed a fishtank heater.

I??m with you there?.my clone dome likes to see 80 ?? 84 degrees.
Heat is the issue?.the options as I see them.
1. Use a heatmat
2. Slow the recirculation to the reservoir to add a little more heat to the manifold.
3. Increase the pump flow to the manifold to overflow manifold heat into the grow chamber.
For the moment that looks like an ??adjust on the fly?. Good thought?.it makes me consider setting the reservoir higher??and shunting off excesses in pump flow or not as desired. Yup, gonna do it!

What we found is if it's just fog all the time the roots become very lacy. If the fogger shuts down for even a hour those lacy roots dry and are damaged for good. If no roots have reach the water level then it's just about all over.

With the prevalence of 15 minute segmented timers (cheap) on the market, I??m beginning to think in 15 minute increments. Like 15 min on and 30 off. It??ll be interesting to see how this all ends up?..like how much flow?.how much venting?.at what relative humidity. Gonna be fun. I appreciate your spending time and your experience.

OM,
what I found was; going from a regular clonner that just sprays water around, there is a lack of fine lacey roots so when the rooted clones went into a fog based enviroment it took a week to ten days for them to adopt (really grow) fine hair roots. The reverse probably holds true, but the transition may be easier since there will be some tap or water roots avaiable for the plant to use.

I got it backwards?..again!! So what??s new?

As LOC NAR pointed out, the hair roots are very delicate, but they are formed after the first roots emerge that are water roots. So there should be roots "reaching" down towards water to sustain the plants if the fog takes a holiday. In my aero/fog grow tray I stopped both the aero and fog for over an hour with no damage to the hair roots. The humidity level in the root zone never reached the point of the hair roots drying out after an hour or so, not sure how long it would take but again there was a lot of water roots laying on the bottom of the tray so the potential to completely loose them seems remote to me.

I very much appreciate knowing what to look for?..very useful
I actually hadn??t planned on a very long stay in the cloner?..just enough to move them down the line to the pre-veg bubbler. Would I be wrong in guessing that to be about 3 weeks. I also hadn??t planned on any feeding until the transfer. Any thoughts on that?

I think a good starting point for you would be to run the pond fogger all the time and spray for 1 minute every 15 minutes or so. But once you get this thing up and running you should get a better idea of how much fog you have and what the cuttings need.

That answers a lot for me?.the timing cycles had me going in circles.
I never really had a full understanding as to why you had the need to cycle the foggers off. The only thing that I could be clear on was, yes?.overfogging is possible.
The variables are so many?..density of fog, micron size, dryness of fog, humidity of the fog chamber.
My intuition is that the output of the single disc pond fogger could justify full time fogging?..it??s reassuring to hear it from you.

Now to the part about spraying?..I??m not going to spray?.I??m going to bubble splash. I have no experience with sprayers, so I have no mental framework to compare from. My guess is that the gentleness of the bubble splash would have much less influence than a spray.
What I hope to pull off is using a $10 hardware store timer that segments to 15 min intervals. From what I??m learning?.only the appearance of the roots and lags at transition will teach me that.

Oh you young people and your strange "blue" strains. I much prefer to grow old school strains like "yellow #2 ticonderoga"! Exactly what strain of blue is that? They look like they are stretching. LOL

It??s a strain given to me by a local. He called it SS (a Silver Haze X Skunk) I truthfully had no idea that it was a blue strain. I know that you often grow PPP, and the more I learn about it the higher it moves up on my to do list. And any stretching is a result of sharing a light with larger plants in the pre-veg bubbler. One of the biggest reasons for this project is to have clones at the closest stage of development as possible??.wish me luck!

( To interject a thought?.Weeze, was Hi Homie totally lost to rustlers ? )

I??ll close here and go to work on the flow report from the shop
Thanks all,
