I was told by the zoo I bought my (very expensive) Juniper bonsai from, that I could have it indoors as long as it was warm enough, and I have it under a grow light. However, everything I am reading online is saying they MUST be outdoors. I live an apartment with no balcony...... Can someone confirm this is true so I know if I should return my bonsai? I've only had it for a few days and I've been putting it under a grow light for 14hrs/day. It is 70+ degrees in my apartment as well.

Wrong.

This is a repeated question that is answered several times per week. Use the search function and look for Juniper.

Are you sure that the zoo wasn't talking about a reptile of some sort?
This is the complete opposite of what you should be doing to care for junipers.

So...... it can't survive indoors?

Let me help you with that:

Sorry Courtney.f1165 it will not. It might last 2-6 months indoors but that's it. (unless you go to some pretty extreme conditions to simulate it being outside)
