I’m starting to believe that one of the limiting factors in my setup was insufficient humidity levels. My first setup was a standard greenhouse tray with dome. Then I moved up to 10G setup with ceran wrap as a cover. Then upgraded to currently setup 75G but continued to use ceran wrap. I went through couple humidity meters but none of them showed accurate levels. Meter kept showing the same level on dry winter day and extremely hot summer day. Something was obviously off.

Few weeks ago I finally got a glass cover. Since then I noticed drastic increase in overall growth and most importantly – numerous flowers. Could it be all of the following: established environment, water, temperature, circulation, humidity or simply one of them ? I’m not sure but I know that the only elementes that were adjusted are: humidity and water circulation.

I received Cryptocoryne usteriana x walkeri from good friend of mine – Ghazanfar, few months ago. I was told that this plant came from one and only – Jan Bastmeijer. I guess I can cross another specimen off the list.
