23.5/.5 Light

I want to do 24 hours of light right now but my lamp news time to cool so I have been having it on a .5 hr off and 23.5 on. I figured the cycle doesn't matter as long as its more than 12 hrs and I have done 18/6 with no problems. My question is a half hour enough time before the light switches back on without causing any problems?

Good question I want to do the same but leave the lights off for 4 hours and on for 20....But i have had my lights on for 24 hrs thus far..

Either will work fine. The veg dark period is much more forgiving than the flowering one.

As long as the dark period doesn't exceed 10 hours, you'll be fine and safely in veg.

Sweet deal - thanks all... and the lights normally say 15 to 20 min after you unplug that you can plug them back in right? So im guessing my bulb will be fine if its 30 min off.

Whether you're doing 18/6, 24/0, or 23.5/0, consistency is very important. Each time the growing conditions change the plant has to adjust to the changes, and this takes time and energy. The plant wants the same thing, everyday, every night. This is important in all phases of growth, IMO.
