Never heard of it but I have the coco peat. Can you get hydrotron clay rocks ? Or lava racks like for a gas grill ? I use hydrotron expanded clay balls that can be cleaned and reused. Lava rocks can be broken up a bit and used the same way. Try to stay away from rockwool or coco peat unless you know someone using it, to show you. It holds too much water. Go with a drip system and rocks. OH, sweeeeeeet buds man.
