My experience with hydro has been at sea level. In a few months I'll be @ 7500 Ft. setting up a hydro grow. Do any of the hydro parameters change with elevation? Another factor is low humidity in the 15 to 30 %.
Low humidity is the biggest hurdle to overcome...I have a grow at 5800, 6700, and 9200 feet and once you get the temp and humidity beat your good to go..
