Sorry for posting again but there was gap - I thought about autos, not fotoperiod What would happen if changing light cycle 18/6 to 3x(6/2) or even 4x(5/1) for Autoflowers. Anyone try/hear? articles?

I don't think 1-2 hours of dark every 5-6 hours is enough. I Autos should get a minimum of 4 straight hours of dark. There's processing cannabis plants go through during lights out, giving them little dark periods won't allow them to go through those processes.

The only possible reason I could see doing this would be for heat management. Some timers wouldn't even be able to manage it, analog timers would but the built in timer on my light only has a single on and off time. Doing this will likely affect transpiration some but I don't think anything catastrophic will happen.

Well I answered last limelight cause stress but most likely the plant would survive. Would be a cool experiment. I'd like to know the outcome if you do an experiment
