Is there something else I can use with a bubbleponics system than rockwool?
Looking for Rockwool alternative

Haiz Trevor. Some people use rapid rooter pellets as well. I always had the idea if I got tired of rockwool or felt it wasnt giving me everything I needed from it as some point, I was gonna try the pellets. My idea was to germ the seed until taproot....transfer into the pellet(which is some kind of mulch?), wait until the plant popped then do a "double-stacker" and try to fit the pellet into an actual rockwool cube. I figured this way the actual makeup of the pellet wouldnt drop into my rez and the seedlings wouldnt have to actually be touched thereby decreasing risk of shock etc. Just a thought. Times are changing as must we 
Good luck happy growing

After reading about how rockwool is a lot like asbestos in ways, I don't even want to mess around with it.Haiz Trevor. Some people use rapid rooter pellets as well.

Rapi rooters are inert and do not need to be PH'd before use, like shitwool.
Minerlaz, you're doing too much with the "stacking" and dropping a rooter into some shitwool bcuz it can still give you the potential problems of PH imbalances and such.
Pre-soak, not dropping if held in the air, the rooter with a mild veg feed ( like 100ppm's ) or just plain water if you're using tap.
Drop the tap root in, sit the rooter in the pot on about 2 inches of hydroton and then fill in all around until it's secure.
I keep the top of my rooters level with the top of the net pot, which is a good measure for more.

Honestly you can use anything as a grow medium with dwc.
I've even seen fish tank gravel used instead of hydroton or perlite.
As long as the roots can push their way through it, you can use it.
I have a theory/invention I want to try out.
I want to make like jello blocks, not flavored but gelatin that will cure like jello, and mix in root hormones and a small nute feed. throw some clones in there and you could watch the roots grow through.
Imagine a big 12"x12" block of this gelatin type stuff. It would give a new view to watching roots
or just a small 1" cube you can throw a small clone into and throw it into the system.
I think I'm onto something.

that reminds me of like something they did on mythbusters with the bamboo growing through the bulletin gel

I misread the wiki. It's not considered a carcinogen.
