Thats what I was thinking......Then by all means keep using the DW!! With the kind soil set up I'm thinking now it's probably PERFECT. because you're not adding anything to the soil with DW because its stripped of everything.
Hmmm... Well hell. That makes perfect sense! Hell stay with the DW! If it ain't broke.. And thank you for the slap!
When I was still doing DWC I would hand water through the top of the hydroton until the roots hit the rez......after doing that for a week or so I started noticing white stains on the hydroton (not that kind!! ) from the minerals in the water. It wasn't super bad....but it was there. I figured this is probably why I was having so many problems.
