Lunar means having to do with the moon. I think you mean astrological gardening.

I remember my grandparents always having moon/sun sign books, pretty sure they are for growing like this, not sure where to get them, i just remember them having them when i was little, they used to have some pretty big gardens, anyone know where to get these books from?

Try the Old farmers almanac, it's got all the moon cycles in there, when to quit smoking, mow your yard, cut your hair. Hell it even tells which stages of the moon to go fishing.

It's confusing at first, but keep on reading it, you'll get it figured out.

so am talking about here two diferent things astrological gardening and lunar gardening do they complement each other???

I go by the moon, it pulls the tides here on earth so it's pretty powerful.
