Welcome to the forum, glad you found us. I agree with your identification as a Ginseng Ficus. This is the common name for a variety of Ficus more formally known as F. microcarpa or F. retusa, I'm not sure which is the more current designation.
As far as being inside or outside, during the summer I prefer to keep everything outside only bringing tender plants in when it cools in the fall. I have a long enough growing season here to make this worthwhile but other growers, in more northerly climes, prefer to keep Ficus indoors year round.
Jerry Meislik (AKA Bonsai Hunk) is one of them. In his area he has determined that it is not worth it to transition them twice a year and instead prefers to grow indoors exclusively. He is a serious grower and has gone to the trouble, and expense, to provide his trees with an excellent indoor environment.
Most sources suggest 50F as a minimum temperature for Ficus and while that is a good rule of thumb I have had mine withstand lower temps than that. Realistically, although a cool night (within reason) will not kill a Ficus there will come a time when you will be forced to bring it inside for the winter. This means that supplemental lighting will be very beneficial, if not mandatory.
Explore the site I linked to above, Jerry is well known for his expertise with Ficus. Don't hesitate to inquire further or just let us know how your tree is doing.
Be careful about the watering it everyday thing. Improper watering techniques are one of the most common causes of problems with any potted plant. Try using the chopstick method, outlined at the page below, to tell when to water. Always remove the inner pot from the outer one when watering and only return it after the soil has drained well.
Thank you for responding, it helped a lot. sins I got no questions from the other pages.
But still I wonder way the leaves is brown. I have not water it everyday now, sins I feel I can over water it.
So you say, it can stay out nightings in the summer even it gets a little cold? sins I am not sure from the or tempratures in norway. it can get pretty cold in the nights, even in summer.
