Switching from 18 Hours to maybe 14 after Strech?

[Cringer]

I ask myself can i lower the volume of Hours after the Strech is done to save electricity cost? I grow autos for long time but never try it to go down with Hours on to maybe 14 from 18 Hours per Day why not?

If your light has enough power, you could go down to 12/12 like @automan2 and there would be no issues.

OK Cool that's what i thought so why waisting Energie away thx

Were all in the same boat with cost especially in the next few months but you could run them on less hours and maybe get a lower yield

Not necessarily wasting energy if you're light doesn't have enough output to be adequate for flower. The length of time the light is on+ppfd well give your Daily Lighting Integral so if you can achieve 900ppfd or around 30+ DLI then it doesn't matter if you get that over 12 hours or 24.

Are your familiar with DLI or ppfd?

Lower Yield i don't want that lol

No I am not familiar never here that?? I using for 80x80x160cm tent 4 x 60watt cob leds total Watt 220

Understanding LED Grow Light Metrics

Metrics Matter… Wait, What Are Metrics? Trying to find the best grow lights for your application can be an overwhelming process. In fact, researching the topic might leave you with more questions than you started with. After all, not all of us are qualified engineers or plant physiologists, and...

It's a lot of go over but those videos might help. These metrics will help you determine optimal lighting for your space. Do you have a link for the lights you own? I may be able to help you find the right amount of time or minimal that you can run with your current equipment.

If you lower your light cycle, you’d probably want to bump up light power/intensity to maintain proper DLI.

You wouldn’t necessarily save energy. Your kWh’s would work out to be comparable if you maintain DLI.

I'm not 100 pcent your yield would suffer and as the more clued up folks said its dependent on your lights power ect
