When I used Coco I would make a 25 gallon tub of nukes then dip each pot into the tub, and let each drain above the tub.. ie manual flood and drain.
You can cut down on waterings this way. Why i stop the Coco thing, too much watering.
I like how they say your barium is right at 2000 mcl thats the exact upper limit that any higher the epa should be involved... lol
It sounds lame, but Im so excited to go home tonight and whip another batch of feed using that new pH meter.
