Had some issues and kinks to work out with the system at first - really, really would've been totally avoided if I would've used aero clones (roots reach into the column) and not clones rooted in pucks - fucking EZ Clone - had a few dry out and die on me (have been replaced), but it also means that the plants in the 4" wyes (closest to the misters) are much larger than the others because they've been growing since day 1, as opposed to some which just started growing a few days ago.
Current misting times are ~6 seconds every 75 seconds to make sure that all plants are getting sufficient moisture, and that means that the larger plants are getting overwatered (in HP terms) and their roots look more like LP aero roots - as soon as all plants have a sufficient root system, gonna cut that back to 2 or 3 seconds every 2 or 3 minutes.
Um, that's about all that comes to mind - looking at the pics, all the new growth is healthy, so any brown leaves are from their "clone" days before they started rooting in the system.
All in all not too displeased - obviously there are gonna be issues when trying something like this, but I feel like I've got everything under control (for the most part).
Gonna top the largest plants in a couple of days and then put up a screen and start training them all through it; shooting to flip the switch in two weeks.
