Although it is more convenient to purchase all of your growing equipment from a single manufacturer, there are times when you find that you have different pieces from different brands. This can leave you with the wrong types of connection when it comes to installing your equipment correctly. The good news is that you can resolve this problem easily with our Cable Pack 12. The cables supplied in this pack allow you to convert any Gavita connection to a SystemAir EC fan connection for added convenience. These cables are suitable for use on either the Gavita fan balancer or ELF controllers.
