Coco Coir PPM Runoff

Is there an ideal range of ppm runoff for Coco grows? Or should they be the same as the incoming water?

They should be close to the same, going in and out.


Raw or un amended coco will only have what you put in it. I grow in coco and feed daily maintaining 900-1000 PPMs with liberal run off :love_you_gesture:


Thank you both!

I sound like a broken record sometimes, but go to That website has all the info you’ll ever need for growing in coco. There is an article on there about runoff ppm and EC. It’ll tell you more about it than you ever wanted to know.
