I wasn't meaning to veg under 12/12, I was just in a flowering stage with no where else to start my seedlings... So, I went with what I had.. Didn't have any revert time. I killed the lights like normal to start the flowering (Day 15). Day 17 the lights came back on. I haven't notice'd a slow in growth at all almost 4ft high 2 weeks in flower and only a month old.

LoL, scratch that
