Andre, I have to admit i feared i wouldn't be able to bloom javanica but instead it looks like a solid bloomer! I have two ot them and both are throwing out new spikes. I guess they just like in the florarium that much. I keep constant 20-22 degrees and 98% humidity in it. I have ventillation too but i don't use it every day. I just open the doors for a few minutes daily to exchange air a bit. I water every 2-3 days, only spraying with tap water gently (btw i don't recommend tap water in general, i just use it coz it's not that bad here where i live). In the summer the temperature's a bit higher, but it never goes above 30 degrees. So far it likes to be mine, bought it last spring and this is the second blooming period already.
It's not as good as i expected but it has a few more buds to open
