i wonder, what exactly is called light poisoning? is it the continuous interruption of the dark cycle ie a beam of light that was not detected by me or ie I walk into the room for 10 sec when it is dark cycle? what happened was the following, this morning around 5-10 mins before the lights went off there was a power interruption in my building....the assholes from the power company were installing something new downstairs in the power meters and as a result they have cut the power unexpextedly, only for 2 secs though....the power came back on, but, i was worried for the plants and the lamp you understand what i mean? when the power cuts and comes back within 2 secs, the lamp does not have enough time to get cold and then back on again and being connected to the plug it tries to get back on but it doesn't....i got into some kind of panic and run straight into my growing room only to discover that the lamp was off, the timer was working good (as it should be) and my ladies have started their sleep.....can this incident be consindered as a light poisoning? i did not stay long, the lights were down to minimum and the growing room is light proof......right now i have the lights on from 9pm-9am and i am changing this one hour back, from 8pm-8am.....the assholes from the power company are not going to bother me anymore!!!!should i worry about the plants? i repeat....this took place maybe 3 minutes or less from the beginning of the dark cycle!!!
