Lighting Schdule For Autos??

[ZuuTeD614]

I always just grew FIM seeds, I am wanting to switch to Autos and test some. What is the absolute best lighting schedule for Autos? 18-6 or what? Thabks everyone home to here from some people soon!

The best one is what works best for your setup. So tell us about your setup.

I only did one auto run and I did it with 20-4, I didnt have any issues and plants seemed to enjoy it.

I have a 2x4 tent that 84 inches tall. I run a 4" Ac infinity out take fan with 67 remote, light on- Temps average 70-78 and 50-55 percent humidity and lights off 63-65 with about the same humidity. And 2 -300-60 watt LED Mars Hydro Lights.

Whats it sativa or indica? I heard 20-4 for sativa and 18-6 for Indica or most strains. So thought I would ask some professionals.

It was mostly indica leaning hybrids if im not wrong, one was Gorilla Glue Auto, the other was Gelato Auto. Keep in mind tho they were not the original strains I dont think

I run 24/0 in my auto tent. Makes it super easy to manage temps and rh. no automation needed, no timers, no swings in temperature or humidity when lights go out. just dial in the environment you want for the growth stage you are in and monitor. No downsides unless you care about the couple extra hours of power usage.

24/0.

wear and tear on electric things turning off and on too.

24/0.

When do you let them breath?

never.
i veg photos 24/0 too. C3 plants.

Cannabis respires and transpires under 24/0 light. As stated it's a C3 plant.

Honestly still question the method. Still listening. Max 20/4 here. My grows are better if I allow my plants to fully cycle everyday and repair or rest during the down time.

But I always say whatever works for you. Our variables change by a dozen miles in locale. LOL.

LOL. The breath was a joke. Yet is it not needed to rest for health by means of stress reduction is my point.

Focus on your setup. Sounds like you can get away with any light schedule you want. If you feel your lights are over powered for your tent, run them 18/6. If your light is lacking leave it 24/0.

I ran 20/4 just to get the most light possible but still have a decent dark period as well. You can choose any you want.

i think DLI is a big factor on whether or not plants droop from too much light.
but with 24/0, it's much easier to control and maintain temps. during the dark, i'd probably need to run a heater. i'd rather give them light than heat.

Central air and overkill fan with temp controls. No issue. External drivers. And a cold blooded brass girdle wearing wife in winter. LOL. I was wrong. Variables change by mates. LOl. I also would make spices if I used my lights on full.

i don't do autos anymore but i think for them (if i did again), i'd turn down intensity for vegging phase and then crank it up for flower. but still keep the 24/0.

my veg leds are pretty weak compared to my bloom led room.

like you said, there really isn't a right/wrong answer. to each his own.

Thanks I did a Auto Great White Shark and it came out really loose and strainy buds and I did 18-6 you think 2 extra hours of light would have harden the buds up?

If you are at or below the plants max DLI there is no need for darkness in veg, or ever for autos. Plants below that DLI level don't need "rest" or "repair". It's just not a thing.
