What is funny about the word FLUSH? I don't get it? What is so hard about some plants in dirt and some in hydro where you make useless comments?
Because the "final flush" is an old school hippie MYTH! It's NOT a way to better taste and burn over a quality, well managed dry and cure!
Your practically useless!
Sorry, if I come across the wrong way, to every one. When questioning a new way of growing, it helps to understand why. The reason a person would flower under 11/13 as opposed to 12/12 is because pure sativas foxtail and take longer to finish under 12/12. 11/13 also brings out any intersex traits that wouldn't otherwise show. 12/12 is perfect for most strains.
Foxtailing is genetic in most cases. HEAT can be more of an onset cause then lighting times (but longer times do contribute to some). Longer running Sat's tend to foxtail when they are done and being run too long.
I run 11/13 over 12/12 because it is less stressful and you get less stress related problems. I firmly believe this along with DJ Short and some others.
The following is not related to comments I made to Chim - Chim!
Cannabis is a C3 plant - not C4 (Hyroot's post)
Cannabis does not REQUIRE a lights out time BUT (and I've said it before) I believe it does my plant better then not! Search up "Light saturation point in C3 plants" and read up on the cellular changes that the plant goes through. UB is a staunch follower of the LSP and giving a "night" to his plants (if that matters at all). The point being that the plant will
more effectively photosynthesize
after a "night' period. Could it be that not doing a lights out nearly balances the difference? No available information on that thought as I can find.....I'll turn them off for the money saved and the plant process being better after so.
If you worry about nodal spacing, why run 24/0 and not work the deep blues more and see that works just as well if not better.
I do spectral manipulation with my T5 vegging before they spend their last 14 vegging days under a 1K MH.....
I know Satived,,,You like 24/0 and so do others. I'm not saying that either of us is more right then the other. Only that we both present correct opposing views.
The bottom line on 24/0 vegging is more like "Do what makes YOU comfortable, as they both work!!!"
BTW I like 24/0 for cuttings and seedlings till the Solo cup. There it's straight to 18/6....
Someone said earlier that an Indica strain can flower at 13/11. I've actually seen one do it at 14/10. It was a seed from a Pound of Napali finger hash found back in the 70's.......I sure do wish I had that strain back...
There's my 2 cents on the OP's question.....
Now can we get back to the humor?
