Irregular lighting

[Agressor1]

How does sporadic lighting periods affect growth?
I ask this because there's been a few occasions where my light has been off when it shouldn't be.. and caught 3 hours of darkness one time and 8 hours another..

Don't sweat it. If flowering they'll get over it, if vegging no bg deal at all.

If vegging, quirky interruptions aren't usually a problem... but during flowering, on the other hand, you should make sure the photoperiod isn't interrupted. Light leaks, FREQUENT interruptions, etc., can and will stress the plants, and often times make the females grow balls (hermaphrodite).
