Lights out.....

My plants are 3 weeks in flower and my power went out 1h into the light cycle last night and for some reason did not turn back on. Went down this morning and humidity was eighty percent, the light was off for 11h of 12.
Is there anything I should be doing?

Nope. Just try to keep it from happening again. They should be fine with the one humidity spike, as long as you turned the fans back on and all.
