They tend to grow into the direction of the water flow and fall off if they get too thick making a layer of crud in the bottom.
There is a sweet spot under which these effects are not a problem.
I'm assuming that the SG7 has found and is using that perfect water velocity range commensurate with the electrode spacing and current to prevent crud buildup and drop off.

Can I jump in here? We use 7/16 to 1/2 inch spacing on our SG7 Pro. With the electrodes that close together the current gradient between plates is pretty strong right at startup and we reach current limiting very quickly. However the water has to be moving fairly rapidly or the unit will shut down because it senses voltage drop across the electrodes to control the shutoff point. We use a submergible fountain pump to keep the water moving vigorously. The idea that it takes very slow water movement to produce good CS doesn't have any effect on our generator. It produces particle size in the general range of .001 to .005 microns.<<<<
So, I think closer is better if you can keep the water moving. Why have to wait to get up to speed?
My 2 cents.

Hi Ole Bob,
Wouldn't spacing the electrodes farther apart be a "good thing" if you were producing a couple of gallons at a time and your power supply was set up to compensate for it? It seems to me that it might speed things up a little. Does a slow start (low voltage) or a fast start (higher voltage) make a difference if the final current is limited?

Hi Andy,
The current drops down and it takes longer to get to the current
limiting level.
