The thing about your statement is that what you see (the conclusion) is the result of the science (the whole story, the plot, and the main players).

When Joe Grow shows you a picture of his monster plant that he said is a result of changing XYZ to ZYX he made, you are missing ABCDEFGHIJKLMNOPQRSTUVW factos that the XYZ change did or did not change.

Here is the clincher, without the science you will never know if changing XYZ to ZYX is what actually caused the monster crop or was it thatif changing XYZ to ZYX under HIS CURRENT ARRANGEMENT ABCDEFGHIJKLMNOPQRSTUVW that did it. Your Q maybe where his A is.

Case in point, Joe Grow typically has 9 ounces per plant on 24/0, Bro tells him to switch to 18/6 for a bigger yield, he has proof in pictures. Joe Grow tries and gets nothing more worth telling. Joe College takes Joe Grow's advice gets a pound more per plant and swears by Bro's science.

Well, actual science proves 18/6 does zilch for c3 and c4 plants. So WTF?

Truth is, if you look closely at Joe College's setup, he most likely did something else that without science he will never know. By this time a new sheriff is in town, the word is out and everyone is doing 18/6 in hopes of getting Joe College's results or better.

Across the growers, their results look like the NY skyline, some huge, some tiny., some medium and some no change. The scientific Truth is hat 18/6 had nothing to do with any results but their individual setups, nute regimens, PH, RH, Temp, CO2, Genetics, wattage/sq foot and the list goes on.

At this point Joe Grow simply thinks he is a bad gardener. Science saves you time & money, increases your yield, and boosts your confidence that you are not guessing results from pictures
Wow. Yeah Bang^^^ this all day this

Well, I could have gone further in college but I was too busy GROWING, SMOKING and counting Jacksons. I do have to give MJ credit for my Masters, With a BA in Bio and no job prospects or real work experience back in the 90s, I had to stick around academia and keep doing what I had been doing for 4 years, GROWING, SMOKING and counting Jacksons. I came highly recommended for grad school by a few good old professors who had a genuine interest in me sticking around and you know why...TA positions opened up real wide and the rest is history my kids will never know. I should have stuck around for a PhD but that three year summer I got really high and then came the fuckits. So I continued doing what I really learned in college, GROWING, SMOKING and counting Jacksons.
I call bullshit. You may have sold weed but I'm not convinced you have ever been a successful grower.

Yeah after all this swampy presentations, at some extent he may look like a wiki son..anyway he's givin input around lovely things like this
We know that the ability to anticipate light/dark cycles gives organisms a fitness advantage. It is common sense that most organisms have the innate ability to measure time. In fact, most organisms us included do not only for instance react to sunrise but, rather, our bodies anticipate the dawn and adjust their biology accordingly.


btw thanks riu & bangaman for the syntactic forgiveness

In this room I run experiments(trials) with different methods including some bro science I think might make sense. I run 4 rooms at once. By the way, Wiki is good. try it sometimes

OK... so just to make sure where we're at... you make sweeping statements ridiculing both what you call "bro science" and anyone who takes it seriously, bu-u-u-ut.... you have no problem using it yourself when you feel like it.

You ridicule people who post pictures to show what they're doing with their grow, because nobody can prove they really took the pictures, so they're meaningless.... bu-u-u-t..... when people are skeptical of your real world experience, you immediately post pictures to show your grow.

You obviously know a lot about botany, but the more I read of your posts the harder it is to figure out what to pay attention to. A little consistency might help people get a more solid feel for who you are and what you're about. No offense, just sayin'...

If my final product is the result of dumb luck, I'll take it. I may not have a firm grasp on botanical science, but I know my plants & know how to keep them happy.

All I got to say is somebody that comes in here and throws opinion on a 6 year old thread that has not seen the light of day for those 6 years.....Why?

Now you dug up the dead and the original postings still stink!

Start a new one or counter post a new one......

BTW, Yup, the plant does not "need" a lights out to function and grow...But MANY still choose to use one! They are not wrong and neither are you.
Personally, I feel the relationship to the plant of the "Light Saturation Point" in C3 plants, and what physical changes occur during a "lights out period" in said plant because of the aforementioned "LSP". Outweigh the gains in 24/0 lighting times outside of the first 4 weeks of the plants life....

But really - Do what works for you!

Forget about 6 year old BULL SHIT that nobody reads any more.

I understand wanting to set the record straight......But here, the record keeps skipping.....You'll figure out what I and many others mean on that-----soon enough!

PEACE - Bangaman

Sounds like I hurt you. Do you Need some TLC? Tylenol, maybe? A good joint?

No seriously, Some bro Science is not in books but warrants investigation. Eg the concept of arrested development in monster cropping. If I cannot disprove it scientifically, yet it sounds plausible, I investigate

You guys are way over thinking this shit.. I did a few comparisons of 18/6 and 24/0 but in the end I couldn't see a difference so I chopped my veg light bill down by 25%. I ran 24/0 for the entire first year I really started growing indoors so after the testing I switched to 18/6 but nothing changed in progression. Do a few tests personally if you think it is worth paying 25% more to run those veg lights 24/0 then at least you won't have a nagging feeling anymore

There is so much research out there by qualified people for me to jump on bro science without proper investigation

Interesting, 24/0 chopped my bill down by about 25%. Makes me want to ask, Did you not see faster growth? I did the same and consistently reached target height much quicker with 24/0, this quicker time to "flower size" was my cash savings-not that 6 more kwh daily made that worth of a difference but I like the time savings. Veg longer or shorter

Plants perform different numbers of functions to differing degrees depending on it being during hours of light or hours of darkness. During hours of light the plant will take in as much light to use to create energy as it can, but it is limited so the total amount of energy to rely on is also limited. Plants allocate certain amounts of energy for different functions and during hours of daylight they perform most plant functions so each function receives its portion of the overall amount of energy, which can be small.

During hours of darkness most plant functions are cut back or stopped and the plant operates on stored energy, as if it has rechargeable batteries for night use. To maximize its stored energy use all energy is allocated to a limited number of functions compared to the number of functions occurring during hours of light. Certain plant functions will be allocated increased amounts of energy during hours of darkness above that which they receive during hours of light. There are various reasons behind how what is done and when and in what amount and why but basically the most important plant functions at that stage of growth receive the largest allocation of power nightly.

Have you ever noticed that over an entire day while you might see growth if you check your plants several times in a day it is not much but it is not uncommon to check them first thing in the morning and think, Holy Hannah, I have to raise my light .. those things grew like weeds last night. A plant is allocated more energy for growth during hours of darkness than they are during hours of light. People tend to believe it is just because they were asleep and not looking often enough to not notice the growth so when it is all seen at once in the morning naturally it seems like a lot. But that is not the biggest part of why. It factors in slightly but it is mostly because that is when plants have the needed energy to grow that fast.

Another key night function, during flower and more and more important as it goes on, is the rate of THC production increases at night, increased amounts of energy are allocated to THC production during hours of darkness than during hours of light. Put very basically THC works like sunscreen within the heads of THC producing trichomes. It protects the delicate inner workings of the trichome-head. That means that while some THC is produced during the day, due to low energy allocation there is a net loss of THC for the day, more is degraded by light rays than is created. During hours of darkness energy allocation for THC is a priority and enough THC is made to replace what was lost and then an additional amount and over time you have a slow steady increase it total amount, and then you just have to pick the right time to chop and you’re in like Flynn. But it is during those hours of darkness when the true slow but steady overall increase of THC actually occurs.

Speedier/increased root growth has been mentioned, and that as has been said means stronger healthier more vibrant plants and it is another example of what plants do and when and how lighting will effect or alter what they can and will do.

Plants lived in conditions of light and dark for ages and ages and they pretty much grew accustomed to how to use the different periods to their best advantage, since it was of course they best they had to work with, and they figured things out pretty well for themselves all on their own. Normally when people try to fiddle with certain things like light and dark and amounts of each, once past a certain point they might believe they see a gain, even when one is not there to be seen, but there is almost certainly a loss they are failing to see exists.
In other words the darkness causes the plant(s) to complete their life cycle...like a fish does in a river under the correct environment :) Without darkness a so-called female marijuana plant can live indefinitely in the correct environment.

And there you go again with the snotty, condescending bullshit. It's never very far from the surface with you, is it?

As I said earlier, you obviously know a lot about botany. But I agree with those who say you don't seem to know much about growing, and you sure as hell don't know shit about how to get along with other human beings. I thought at first you might have some things of real value to add here, but frankly you're too much of a self-absorbed dick to make it worth the effort. There are a lot of other people here who have a lot of good information to share and who are actually civil, respectful human beings. It's a far better, and less annoying, use of time to converse with them.
