Switch from 18-6 to 12-12 to finish Autos?

I have a Spider Farmer SE5000 crammed into a 3x3x6! 24/7 with the light at max. Should I change my light cycle?View attachment 5066849
How close are the lights to the tops. I'm going to say 100% is probably way too much especially at 24/0.

PPFD map is showing around 1000 μmol/m2/s.

1000 μmol/m2/s over 24 hrs is a DLI of 86. That's close to double the recommended amount of light.

Plants can only absorb so much light. An excess can cause light stress.

Im almost in the same boat, last frost at end of may to start of june and first frost September. It's hard to get to the end with something that isn't rotten or frost burned lol. This year i hauled em inside to finish cause it wouldn't stop raining and temps dropped to 10 degrees at night only went up to 14 in the day.
Same here. Rain and more rain. The nicest auto I'd ever grown got bud rot. So it didn't get to hang around. Sadly.

You can literally throw a constantly varying light schedule at autos, and they'll keep going. You're probably gona lose bud density with anything less than 16 hrs light per day.

The weird thing about autos, they're "day neutral" but they still require more light hrs per day, to maximize their benefit.

Y'all, I didn't point him to download the app.

I pointed him to the calculator for DLI. If you haven't tried it, it is about the best of the online DLI calculators. Y'all didn't bother to actually look at the link beyond the title.

This whole 'what's more accurate' conversation doesn't need to happen. (Also, I've pointed out many times before that there's better for Android but it's great for iPhone).

I am on desktop and I cant enter anything in the calculator. Its basically a power point where I just click "Next"

Is this normal on windows or am I missing something?
Works for me on Apple & Windows laptop platforms as well as on my iPhone without issue. Did you use the little slider to adjust the numbers along the way?

We're aware you pointed him to the DLI calculator. A side discussion surfaced about the app.
So yes the whole "what's more accurate" discussion is pertinent. Have you "pointed out many times before" about other apps in this thread?
