What do you mean by this?

If the roots of a pot plant are 100% saturated they will start to die or suffer root loss after 15 minutes. Unlike lettuce and other plants, marijuana requires a dry time in between watering. Constant flow systems are prone to bud rot and root loss, even though they start out great. The larger the root mass the more susceptible to damage due to over water saturation.

100% saturated

Maybe I misunderstand but I am not sure what you mean by 100% saturated.
Do you mean that plants can not be surrounded by water continuously?
What about DWC then? Plants are surrounded by water all of the time. No dry time at all. Plenty of DO however.
Or do you mean by water with no DO at all? Then lettuce and herbs will also die.

The air stones used in DWC reduces the saturation rate. There's a thread on RIU from some time back that has calculated the amount of air needed to run the roots in water constantly. In systems like this it is best not to have any suspension at all other than the net because any suspension will retain water and this will be where problems will start.

As mentioned earlier, some hybrids can survive saturation and it doesn't seem to effect them but land based strains that haven't been screwed with can't survive this.

In any event it's best to get them out of the cloning bin when they are rooted and into an appropriate medium, and when the buds get big, it's a struggle with bud rot with constant flow systems, when it comes to land race marijuana.

Every grow-op is different, depending on local climate and elevation. It's up to the grower to determine what will work best in every situation. There is no magic bullet, just a whole lot of math and theoretical calculation based on positive knowledge, but once it's tweeked, it's a boring job and repetitious, the writing is usually on the wall

I prefer mini-greenhouse, and since it's already in a garbage bag
Any pebble like gravel can be used to set the clones on for proper aeration and drainage in a mini-greenhouse.
I've learned to use the soft rockwool, I just bank them with clay gravel for added support.
Rockwool, if used should be used sparingly.
We have found that Stimroot number 2 is most effective in helping to establish roots.

I packed a few boxes of snips and sent them off. I used paper towel and colored tape, them I dipped the paper towel in res water and placed them end for end in spent tinfoil boxes, no doubt from the tinfoil hat party. The guy didn't have the room for all the snips. He forgot them in the cupboard under the sink. When the guy checked on them the box was full of roots. I found this astonishing because I didn't add a rooting hormone. The snips were extra long so the grower could just snip off the thing I attached to keep them alive and root them, the color of the tape indicated strain.

Like I said, Who knows, until you get there.

I am really sorry and don't want to offend you in any way....
But I understand almost nothing of what you are saying.

What does 100% saturation mean? Describe please a situation where it exists.
If Lettuce can grow in a system, cannabis can grow in that same system.
Although they look and taste different, they are not that far apart.
Lettuce will probably do a bit better in hydro systems.

bud rot and constant flow systems have nothing to do with each other.
Bud rot appears because of some fungi and it has to do with humidity and plant temperature and not enough airmovement.

And could you explain this line "In systems like this it is best not to have any suspension at all other than the net because any suspension will retain water and this will be where problems will start.''
What system? What suspension? What net?
