This is not a real "problem" as most of my Neps are terrarium grown and have been slightly lighter in color under artificial lights but I was just cuious as to why the new leaves are lighter green in color than the dark green the greenhouse growth is. I realize it has something to do with sunlight but what is it that causes the lighter color? Need of red light, or blue light, or...?
Can the leaves ever be dark green in the terrarium or with it always be a lighter green?
