How long is your photoperiod?

So now I'm not sure what to do - lol

I will tell you exactly what to do.

1 - Reduce your photo period by 1 hour every other day until you reach 5-7 hours. I would suggest you start your photo period in the late afternoon and thus you will have your viewing time in the evening when you are home. Your actinics could come on about three ours before your main lights come on and then a couple hours afterwards.

Just my opinion of course!
