I decided to make a 1:1 slurry of r/o water and the Roots Organics Coco Palms coir straight from the bag I just picked up last week at the store. After letting it soak for a couple hours I tested the conductivity within 7 minutes and that was .6EC(300ppm) then I tested it a couple hours later and it came out to .7EC(350ppm). I'm not impressed with those numbers at all. I've had some good results with their soilless mixes in the past however I won't be buying their pure coco again.
I've had better slurry readings from coco I flushed from a brick. I bought loose coco assuming I wouldn't have to flush it. I know Canna is good stuff. Feel free to chime in if anybody knows other loose coir options besides Canna that are reliably low in EC.
Also look what I found that floated to the top of the slurry only a couple minutes after i mixed it. I believe that's a springtail? I don't remember if those are bad or not but one of the reasons I get coco coir was for it to be bug free.
