pH in soilless mix

A question from a fellow grower:

What PH Level does your White Widow favor in a soilless mix?
(organic peat moss and perlite)

A true soil-less mix is basically hydroponics, and in hydroponics the target pH is 5.8 and can range up or down about 3 points, so the acceptable range is between about 5.5 and 6.1, this is the pH at the roots, in the soil-less mix, not the water you give it.

Happy growing,
