Not sure exactly what you are asking but you mentioned light durations. We all need rest. Plants metabolize at night or during lights out. If you never give them any darkness, they never take advantage of what they do during the day. So although I use the typical 18/6 even 4 hours of darkness is better than none.
Cannabis plants don’t actually care about rest. There’s a study out there from GW Pharmaceuticals that ends up somewhere around this - for an 18/6 light cycle, it takes 28 days to generate a specific amount of mass.
For the 24/0 light cycle, it took 21 days to generate the same amount of mass.
For veg, there’s no reason to get fancy. Either do 18/6 to save yourself heat generation/energy costs, or do 24/0 and enjoy bigger plants faster.
Same thing is true for flowering autos. No real reason to give them dark time or a lower light intensity period.
I do but I do not agree with lights on 24 hours from experience and knowing all living things need sleep.
Regardless of dimming for night periods but still leaving the light on.
This is a choice as once again there is conflicting info online. The below is what backs up my reason if you need an outside source of info, but I have always given my plants a dark period for metabolizing what energy they produce during the day.
Everyone knows that plants photosynthesise when exposed to light. However, much like animals, they have different processes that take place during the night. It is therefore important to give your cannabis plants adequate time in the dark.
While plants photosynthesise in the day and create energy for themselves, they metabolise their stores of energy during the night. Excess energy captured during the day is not simply wasted, but converted into starch to be used in periods without light. Think of it like fat on an animal. Whether it’s essential for plants to actually metabolise this starch is not entirely clear. What is known, though (from autoflowering plants), is that cannabis plants subjected to constant light do not inherently produce better or stronger yields.
This is exactly what I have known years ago. It really sound logical and like this is how nature works.
When I did my first grow over 10 years ago I followed 18/6 because that is what i learn from the textboks. And I never question this since I thought it made sense.
So when my friends told me They dont give their plants any darkness I thought that They were joking but They didnt because I tried myself and im happy with the results.
I think we still are learning more and more about weed and the science cant perhaps explain everything so sometimes you just have to try it and see for yourself.
Its like the discussion about ”to trim leaves or not”, there is no right or wrong thing.
Its just different method that obviously works, like this method,.
And which way to do it is up to the actual grower to decide.
I understand why you like 18/6 and I think you should keep grow as you like.
As for me, I believe i dont have a definitive answer for which light schedule is the best one since I think it depends on grower, genetics and other things. All I can say is that both way gives good results. Personally i like to try new things and thats why i tried growing with lights on 24h
And I dont regret it. Just like when i tried topping, fimming and other LST or HST methods. It was against what i had come to learn but turned out it worked better then ever before. Despite the lack of science that back it up.
