Hello, to all! I thought I would share this 12 volt fan for that troublesome spot air circulation for your growing area or cabinet that you built or bought. This fan can be bought on ebay from aquaworld ebay username. It has its own power on off switch and can be bent and rotated to where you want the airflow. Perfect for creating those tumbling air pockets that orchids love. It is made by aquatek. I am going on 2 years of 24/7 operation with these fans.
It also has a threaded turn knob for mounting purposes. they sell for around $15.00. But they are very well worth the money
