Aux. red grow light

What would it do to a flowering plant [ just starting] if it was left on more than 12 hrs? 20w Led light 16" away.

I wouldn't worry too much about it if it's a one-off. I have not had to deal with a light left on in the grow area but have left the tents open during the dark period more than once on the same grow, no issues. I call that GWS (gardening while stoned). What is your light schedule? 18/6? If so, the 12 hours the light is left on would only impact the plants for six hours. Still not a problem IMHO but wouldn't make a habit out of it.
