Hello! Recently purchased, my (relatively) first Bonsai is doing well for the few days I've had it. However, I would prefer a learned opinion on the environment I have it in currently -- I'm determined to keep this tree healthy. It's currently next to a glass reptile habitat, with a 100W fluorescent light 60cm away, and the light passes through a 5mm glass pane. The average temperature during the day is around 73 Farenheit. I'm on the east coast, mid US. I did have a small Bonsai, when I was a child, as a gift (I don't remember who gave it to me, but it was a horrible idea). I've been told that Serissas are fickle but I'm prepared to work with this plant. Please, any advice is better than none.
My questions are:
How important is a moisture tray?
Do I need a warm light or is the 100W fluorescent capable?
What liquid fertilizer is recommended for a young Serissa?
Would sand work as well in a moisture tray as pebbles?
Also, generally, what is the optimum environment for a Serissa?
Thank you for any help you can offer!
Additionally, here's a picture for reference. In it, the plant is not in it's current location, obviously.
