How do you make sure, that the ec in the medium of the mothers doesn't become too high. For me, that was the one big thing that I neglected and caused a lot of failure in rooting success.
The reason why I was asking, was this: I watched this youtube video from one of the big famous facilities with their high tech rooms and the interviewer talked to one of the responsible person who was sitting in front of a big screen that showed a graphic display of all the different rooms with all the values for room temp, room humidity and also co2 content in the room. When they showed this, I noticed, that they also have a higher value of Co2 in the cloning room....Why not?
I am very close to switch to aero cloning, so I am already insecure again when I read such comments like yours. But I am really growing tired with peat plugs. The thing that really attracts my about aerocloners are the fact that you can keep the dome off, you don't have to trim leaves, it seams that it works better when you want to have a lot of clones next to each other without a space between them.... This screenshot I did yesterday:

So they really also do it in commercial environments, altough the trays with domes still seem to be the majority....
