Lights went out for 2 hrs, power outage

A question from a fellow grower;

Plants are 21 days old, had 8 hrs left in light cycle power went out. Should i leave them in the dark or just continue with the light cycle?

Just start them back on the same time schedule . If this time they dark period leave them in the dark , if it’s they light period turn lights on .

Yup. Just stay on course. Normally a small period like this will not do harm.

Yup I agree with Latewood
