I have a couple of lines with reds and never did much running until i added vacuum to them. Mine run like a bugger early in the year but dry up quicker than my sugars. These are all yard trees and get full sun. They are usually around 1.8 to 2.0 sugar and i get a gallon or better per tap early on and .5 gallons a day at the end of the season.
