Since no one who is currently using coco has said anything yet, thought I'd throw in my experience with it....

The last and only time I used coco, I found that the coco clogged drain lines, filters and pumps very easily. Maybe it was my setup, I had it on a drip system. It created a headache for me cause I had to disrupt root systems to fix the prob. After that nightmare, I stuck with the hydroton pebbles....

I would say for you to try it and see how it works for you....might work better for you than it did for me....
