Random question on moonlight

When you grow outdoor ganja the nights would never be truly pitch black like it is in the nights in a grow room because of moonlight... just wondering how much light the moon projects and if there were small cracks in the grow room would it not really affect the outcome. is the moonlight a type of light wave that doesnt affect plants ha i'm just stoned and was hoping RIU could explain..

the moon doesnt produce light. its sunlight reflected

right but its still emitting light at a certain degree. It just seems weird that grow manuals ect always make such a big deal about total darkness i'm just wondering if it would do anything by allowing a little crack of light. Basically for example my tarp zipper for my grow tent lets in the slightest amount of light would that affect the plants negatively? If so why doesn't light reflected off the moon have the same negative effect.

Yo i need someone to clear this up for me ha... i really don't get it
