Is it dumb in last couple weeks to switch from 18/6 to 12/12?

Hey i have been running my autos on 18/6, just a dumb thought what are the pros/cons of switching them to 12/12 at this stage?


They are 10 weeks from germination. Breeder stated 10- weeks but incorporating the 3-5 weeks of veg i am thinking they have a couple more weeks still as they just are beginning to pull nutrients from the leaves.

Auto 18/6 from day dot to harvest day.

They're unaffected by light in the same way photoperiods are. It's a preset genetic switch to flower as opposed to light level switches.

Keep 18/6 you'll hurt final yield otherwise.

Also never read the label marketing bullshit same with THC and CBD %.

To get 18% plus is hard, everything has to be perfect, like everything. Same with flowering times they're bullshit too.

Good link here

Thanks, i figured as much But being my first time with autos i figured i would ask. Thanks!!

thc % doesn't mean sh*t to me..

Dumb? No but it would not be a good idea.

I run 20/4 on my autos and it works great. More hours of light the better.

I've heard alot of people running 20/4 over 18/6. All plants regardless of type need dark period due to natural processes and to transpire. What yield gains do you get from the additional two hours?

I've always done 18/6 personally.

Your overall DLI would be higher obviously but off set against energy costs is it also worth it.

Very nice to see someone in agreeance. It's all marketing crap. Another example is nute companies. Never read their doseage guides unless you want dead plants.

That is why you can grow autos in with photos, the light schedule doesn't matter. I do it all the time. I have 2 grows going and both are mixed with photos and autos.

I run 24/0

No

yes

To be specific, especially indoors.
Outdoors it's smart, Veg 20/4 until you run out of space then put it outdoors and finish when sun light goes down to 12/12.
