Our company has an extensive list of commercial clients and they predominately request Gavita's. These arn't grower's that jumped up to a 100 light facility, these are business men from the Corporate world that contract engineer's and scientist's to research the BEST equipment to use in their situation because they're purchasing 1000-1500 fixtures. If you've watched the YouTube channel you can see our video's transition into testing more sophisticated products to educate commercial growers. The 'small grower's' or 'tent grower's' will be obsolete in 2-3 years.
The reason Gavita is so easy to represent is because of their track record and their business ethics, i.e. they DO NOT SELL DIRECT TO CONSUMER. This is what first pushed us to stock the Gavita because we prefer to work with professional individuals.
That being said I'm not biased, I believe that there are specific uses for BOTH fixtures, however, the E-Pap needs to work on the loss of light at the end of each row, that's a start. Gavita works best when using her penetration ability and E-Pap works very well in a SOG style of growing, were the tops are your main focus.
