i've read that 1-2 lumen per sq foot is ok during light period.
As well you can have green lights on during the dark cycle. As the plants dnot react to green light
harris7 Reviewed by harris7 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
