workhorse Posted April 28, 2016 Share Posted April 28, 2016 Hey guys Question for all the pros out there. What's the maximum ppm for your tap water before you reckon you filter or go buy RO? Obviously this will be influenced by hard or soft areas and the growing medium. I have a hard water with a ppm of 160 odd. Growing in Coco. Bit concerned about limescale buildup over time but it does offset adding calmag etc to RO. Thoughts?

Guest kimcarsons Posted May 2, 2016 Share Posted May 2, 2016 Over an EC of 0.2 and it is considered "hard". Not really a trainsmash in coco as the extra mg and ca will help out. RO needs extra calmag for coco. Quote Link to comment Share on other sites More sharing options...
