How so?
As long as the water is carrying as much air as it will hold, and reasonable, (read lowish), nute levels, and keeps moving, you can treat coco like Hydrotron.:thumbsup:
You just can't treat it like rockwool, or soil.

Weezard Reviewed by Weezard on . Bizarre runoff in coco...?? I use a 50/50 mix of Roots Organic coir and hydroton. I just tested the runoff and I'm getting 6.5 pH and 1500+ ppm. I feed every morning with AN 3 part & CalMag. pH @ 5.6, 900 ppm. What is causing the intense runoff? Rating: 5
