Yes, if you let it go too long. Not more than 4-5 days. I've gone longer but
the plants do suffer but nowhere near as much as the algae. Plants can
handle much more dark time than many algae. Plants are regularly shipped and
in the dark for 5 or more days. 3-5 days is typically a good time for a GW
blackout. It needs to be black though, place a thick blanket over the tank
so that NO light gets in there for those days. Water change before and after
