So today I got a brick of coco coir and expanded it. I have to say that I like it because it's a bit more coarse than dirt. Here is a picture of the finished product. I also have another empty 72 cell tray I'm going to use for vegetables. The first one I just put a LOT of medicinal and non medicinal herbs in. This is some Costmary I got too. Also have some Hyssop.
