hmmm didnt give the power outage a thought but the reason behind it all is ..
1) never done DWC and thought would give a try and would like to change my 4x4 tent into DWC instead of E&F.
2) we have been doing continuous clones .... we clone about a week before flower so we can start the next grow and tired of waiting on plants that fall behind.
3) have 2 grows atm 2x3x6 cab which will stay E&F and a 4x4x7 tent which the E&F setup in the tent is wasting alot of space so thought turn that into DWC.
4) thought to start 1 DWC (mother) to get my feet wet (no pun intended) and get used to it before chamging tent over.

now I have a quick question ....... I understand in DWC if the airpump stops then the plants can basically drown, so if power goes out or pump dies what is an estimate on time before drowning would occur?? and is PH a real pain to try and keep in line?? my E&F trays hardly ever change much more than like +/- .4 or so
