How long can I leave my girls out of the bubbler?

My mom is coming over tomorrow and I need to wrap up and stash my flowering girls (week 7!) in the attic, but I don''t have a power source to keep them bubbling up there. They will be without bubbles for (hopefully) less than 8 hours. should I pull the roots out of the water for complete air exposure or should I keep them submerged in water?
This will be happening entirely during my girls' dark cycle.

thanks for any advice

As long as it's not a couple of days without air or anything, for an evening they'd be fine just being submerged. Obviously not ideal
conditions, but you gotta do what you gotta do.

leaves may droop a little but will pick straight back up when lights, pumps etc are back on, they will be fine submerged just make sure you get them hooked up to the power again as soon as you can

Ive seen a thread on here were a guy is running a dwc with no air stone, and things look normal to me

buy an extension chord....
