This is the query I face.

I don’t comprehend how plants can tell the variance from simulated darkness and natural darkness. Let me elaborate on what I am enquiring here.

How can a plants tell the difference from a light seepage inside of a grow tent from the luminescent glow of the moon at night? Is it natural selection? Does the plant know it is in captivity? Every single night in the wild plants are not in complete darkness. How can plants really know the difference?

And I am not speaking about a colossal light leak as if you’re shinning a million candle watt spot light into the tent, but rather a small restrained glow analogous to the moon?

The wavelengths of light bouncing around outside at night are completely different to a feint glow from a light indoors leaking into your veg cab.

UV and far red and all that.
Is your question more specifically about why indoor plants don't manage light leaks as well as outdoor plants cope with moonlight?
The answer is probably very complex and has more to do with the senescence of the plants and their eccentricities of gene expression control than light perception.

A full moon only produces about .02 footcandles of light. whatever light leak is coming in is more than that, even if it seems comparable to you.

the plants have photosensitive cells in their leaves and stem. when there is X amount of light it knows its day when there isn't its night.

The difference in sensitivity to moonlight compared with sunlight is because the sun is 500,000 times brighter than the moon.

As I understand it, the plants don't have specialised cells for detecting light like animals, the light sensitive compound "phytochrome" is distributed across all the cells in the leaf and stem.

Phytochrome is continually being made in the cells and breaks down very quickly on exposure to light. If there's no light for twelve hours then the phytochrome levels build up to a point where it starts a process that initiates flowering.

This is a process that has been well understood and documented by scientists since the 1960s. It is the only reason that cannabis plants require a dark period, although that doesn't stop some stoners coming up with weird and wonderful theories like:

keeping the plant in darkness for the last few days before harvest boosts THC production,
THC is only made during the dark period,
(or my personal favourite)
roots only grow during dark periods

i don't wanna say you're wrong, but i have plants that flower under 24/0.

Moonlight is sunlight bouncing off the moon, indirect light has far fewer lumens, I don't know exactly but I can imagine it is almost nothing.

Great post, El Toker! I learned something.

IMO... hermies from light leaks have more to do with the difference between the spot getting the light leak and the rest of the plant.

I'll bet.... if you put a night-shade over your plants with just a pinhole facing the moon... you'd get hermies on the spot of the plant it's shining on.

Stay Safe!
