Need some advice

can somebody tell me is it a problem if i turn on the light breafly during the dark period while my plants are in veg. 18/6 is there a chance for them to turn in to hermys and when is the best time to water my plants while in flowering

Water them when the lights first come on.

Why do you wish to break the dark cycle ?

Water in the mornin and it wont hurt them if ya turn lights on. Ya dont want to make a habbit of it. (ya know do it all the time)

well turning lights on in 18/6 is said to help get females, but in flowering it will herm them out

During veg i have had no stress problems turning the light on ev ery once in a while. maybe 3 times during the whole veg cycle. as far as flower i never break the light cycle. i currently have 2 blueberries, 1 black russian (girl) 1 giant jack herrer mother in bloom with 16 clones taken, and 5 mids in soil. so far so good.
