I agree homeostasis all around from the room to soil is key to heavy weight buds
Is this a male?

Well if you run it at them full power for 24/7.....yeah that's going to lead to over lighting. By reducing the lights so low that it's barely enough all the temps drop and the soil temps drop as well. There is definitely a difference between going 24/7 full lights or using some control and allowing soil temps to not stay higher. Air temps drop as well as the rest of it you are just not ending Photosynthesis by cutting off the lights.

I really want to see the math behind this 98% increase. Because I'm running autos right now, and everyone that's had a lot of experience with them says to do 24 or 20/4 unless it's new strain then some rare cases you do 18/6

I would say a lot depends on the types of lights used and how they are used really when it comes to auto's.

100 different reads? I bet I can find a thread right here on RIU that says you are incorrect.
Nice plant, BTW. Love the leaf texture & high brix shine!
But what really matters is how they finish...

That is a true hermaphrodite. It's growing both male and female at the same time. Not like a stress induced hermie

OK I guess this all boils down to opinion on how your set up is and what you take as advice towards different techniques in growing weed, best way to learn is do it yourself .So we can just leave it at that lol I'm not hear to steer people into my methods they are just my thoughts and results in my past and present grows OPINIONS are just polite suggestions no harm no foul

Theoretically dark time is a good thing but definitely not a necessity when it comes to growing pot plants. As a matter of fact the space between nodes is far far smaller creating tighter more filled in buds when the light is on 24 7 , but then you have to think about every living thing. All living things heal and recharge and stay healthy by resting. So a dark period is a good thing. These plants have been growing in basically 18 6 for millions of years and you do tend to get best results when you mimick the actual light schedule in nature. Roots do most of their growing in the sleep time where photosynthesis stops with the leafs.

The amount of light matters, specifically PAR. I've got a tray of ladies waiting for tent space that are doing exactly what I want them to do -- under low light (CFL) 24/0. I don't want to repot them yet, so limited growth is a plus. Internode spacing is also minimal to promote maximum canopy density.

Try not to confuse them too much...

Ive grown multiple autos under 24/0 that is probably not the issue, probably bad genetics. Just buy a timer for like $5 lots of peeps recommend giving autos at least 4 hrs of darkness.
And no that is not a male, that is a female that went hermy.

So after growing under 24 have you switched to 18/6 yourself?

Nah but turning the light schedule down to start flower won't hurt anything

I found a pdf with a lot of information about continuous light plant growth. It generally seems to be an improvement, though results vary with the plant species. It doesn't allow copying so I can't quote it. At one point it mentions that a 4-6 hour colder period is beneficial for some plants. Maybe the 20/4 cycle could be replaced by 24/0 with a cool period of 4 hours. It also said that with lower PPF continuous is better than 16 even with the same total PPF per day. So the same amount of light energy produced higher yields by being continuous.
I was under the impression that continuous light was worse than 16 or 18 hours but this article seems to indicate that continuous may in fact be better. The article didn't mention Cannabis but there's a pretty good chance that it would apply to at least auto Cannabis. I haven't read the whole article myself yet, just the first couple pages. Looks interesting so far though.

Like I said before trial and error is what it's really going to boil down too let's say this maybe the lights have a lot to do with my reluctance to ever run 24/0 I use HID lights not CFL people say CFL lights work great but I'll tell you this right now my colas are close to the size of 2 liter bottles and I've NEVER seen a CFL set up pull anything close to that I'll be a MH/HPS guy till the day I die lol so I'll run 18/6 and have the greatest results

I believe plants need a dark period. When you watch a time lapse the plants seem to recharge in the dark. Don't they make O2 in the dark?

Yup cooler soil helps out. I have thought about splitting up time to keep soil temps down.
No.... they dont make co2 or O2 in the dark. They need a less light period and soil temps to fluctuate
They do not even use co2 in the dark period.

Yep your right plants use dark time to release oils and use that stored energy to emit o2 and it helps develope darker colors in the leaves people try to debate this but if they want answers it's out there for them to investigate

If the stomas are closed how are they releasing O2?
please indulge me with all kinds of botany stuff about cannabis.
