Comparettia macroplectron

I've been growing this species over a year in my terrarium. It seemed happy for a while and even put out a new growth. It then put out a spike that unfortunately blasted. I have it bare mounted on a piece of hardwood. The roots were nice and plump/ white for a while and now have turned green.

I have a feeling that I'm over watering it. It gets misted directly in the morning and there's a fan that blows it dry over the course of the morning. Does it need to dry quicker?

Here's a pic


Any help or insight as to how to remedy its culture will be greatly appreciated.

Thanks!

 

Thanks Kelly! I've read that thread before. It confirmed to me that where I had placed it in my terrarium was suitable. I may just redirect the fan so it dries a bit faster. It's already in a very bright spot.
