Is coco coir ok to use like soil in fabric grow ba...

Yea you can use coco in fabric pots. While it's a slightly different grown technique with coco as it's closer to a hydro than a soil in terms of moisture retention and nute feeding. But as for using the bags, you can definetly use them for soil or coco. Could also try giving a little more time between feeding water and add a fan directed towards the fabric pot if you want to stay soil. But if you have decided to make the switch you have bags compatible for both. Hope this helps.
