alternative to rockwool

...hey everyone this is my first post on here but have been reading for a few years .. I've just set up a new room and have been wanting to go back to dirt until a buddy recommended trying coco pots with a soil less dirt .. I have read Alil about it and seems like I wouldn't be able to drain my water after feeding and reuse after .. I have 2 1000 watt lights over 2 4x4 trays..... I was going to get 26 under the 2 1000's using coco pots and coco soil less dirt n running curing edge nutrients .. need feedback.... don't want to screw things up I've ran hydro three cycles now using rockwool cubes but was considering dirt until this came up
