When vegging they are very tolerant of lighting issues. Just don't give them 12 hrs of darkness. When flowering focus on the 12 hours of darkness.

Since the time change I get back on schedule by giving them 11.5 hours light for two days and all is back on schedule.
grey1223 Reviewed by grey1223 on . Light Cycle Interuptions, Oh No! *help stinky* Today upon arriving home, I found my plants in the dark... the power must have gone out. This prompted some questions. 1. Just how bad are light cycle interruptions during the veg phase? Not nearly as bad as if occurred during flower? 2. If darkness occurs when the lights are supposed to be on, this is not nearly as bad as light interrupting the night, correct? If the power does go out, is it best to just turn it back on and the plants will just think a cloud passed overhead? 3. Rating: 5
