The video doesn't tell me anything I didn't already know. I have a fascination and limited understanding of electromagnetism overall. I'm not just obsessed over that which falls in the visible spectrum... but thanks for playing.

I watched the video too, good stuff, it goes beyond what we can see. UV for example. Maybe you watched a different video?

Anyone "inspecting" their plants with any kind of light during their dark period.... is doing something wrong.

What type of emergency was there to justify looking at your plants during the dark period? No issues you noticed.. compared to what?

may be you want to look into how pf and pfr receptors work with cannabis with some specific light wavelenght and how they trigger flowering, hence why some people sometime use green light at night ... or cut the red and far red while keeping blue to trigger flowering early.

Great, now tell us what functions are going on in the plant during scotoperiod, and why they should be interfered with.

you make thing much more complicated than it's needed. some people "exploit" the pf pfr mechanism privating or giving specific wavelenght succesfully. dot

plant are much more resilient than you suggest despite not being the most advisable way to proceed regarding plant natural metabolism.

also i m not doing this personnally as said just some people do it succesfully and the plant don't bother that much in the end.

Exploit and end up with less healthy plants, less bud, less terpenes, because they have no clue why the dark is just as important as light. That's not exploiting anything in a productive healthy way. It's just a way for the ego to feel good about over minding something, but the results aren't what's intended. It isnt a "hack" it's just a screw up that you dont understand. No educated gardener would do that.
You are more resilient than you may think. We can do some audio/light torture/sleep deprivation techniques on you so you dont sleep. You'll still be alive. Not healthy but living on. Let's see how good you perform after a month of that.

Just say you have no idea what role the scotoperiod plays in plant health and leave it at that.

any study/ies backing that you could provide a link or your just speculating ...

i tried to search studies comparing quality of cannabis grown under 24 hours light or the regular schedules, didn't find any ...

just found a study about fiber hemp grown under 24 hours light, nothing about overall plant health and terpenes.

Funny how some folks think they can disguise themselves behind different screen names but their unique writing styles, attitudes and choice of words give them away every time.

I use a UV flashlight at night outdoors because mold and bud rot fluoresces a different color and is easy to spot! Especially on the inside of the plant! Can cover eight larger plants in about 10 or 15 minutes as opposed to trying to pick through all of it during the day to inspect! Dead and moldy spots fluoresce, yellow! More to nip problems in the bud before they become big problems!

Solid reason. 15 minutes is right at the edge. You have to work fast.

People have been studying plants for a long time, not just the past 10 years. Research photoperiodism for your answer of why scotoperiod is important and what it does.

Comparing plant sleep to our sleep is irrelevant because plants don't " sleep " in the same way we do. Sleep is a function of the brain, no brain, no sleep needed. They may function differently during lights off but they don't sleep. But having said that I agree they benefit from a dark period. There may be some truth to what you're saying but with your know it all attitude and confrontational posts nobody is going to pay any attention to you

Just with the extra UV output from a grow light you can see things going on with the leaves you don't see in sunlight. And the sun illuminates things... like bugs... that you don't always see under a grow light.

Yeah, the UV doesn’t illuminate caterpillars! But it illuminates their damage! I’ve never had a grow light, so I’ll take your word for that one! And caterpillars are hard to spot even on a bright day with my eyes! Lol! Fortunately, I don’t have much of a problem with them or mold!

It's an analogy, use your head and common sense. People are also effected by photoperiodism, dark/light cycles. Its s known form of torture to keep people (and plants) under bright lights 24/7. By obsessive focus on light, the understanding of dark is neglected. Anyone with common sense can realize plants have evolved with darkness. It's not their enemy. They rely on it.

If you can't find info readily available to everyone, that's your problem, not my obligation. Research photoperiodism.
