I know Oude Kaas has used this, to great success. One thing I'm wondering about, is the air flow. I think Jos experienced some issues this way, with too much airflow from the a/c essentially driving out flora from the space (I believe he rectified the issue, but haven't seen further discussion on this).
Anyone using the coolbot? Can you talk about this issue of airflow - problems with flora development, or a non-issue?
