From what i could find, moonlight is about .1 lux (lux = lumens/meters^2).
Full moons are approximately .2 lux.

Splifted Reviewed by Splifted on . Moonlight. If plants adapt to the moonlight outside in a outdoor grow..i wonder if its better for the plant that it gets light durring a full moon cycle or something.. Because of the indoor rule about no flowering with any light during the off periods. I think thats kinda funny that it would work that way since i do know the mooon creates alot of light during a full moon even if the lumens arent high.. does anybody know anything about the whole dark period and moonlight thing? how many lumens Rating: 5
