Ya, coco coir and chips are my favorite
growing medium as well. Until recently it has been more expensive for me because I needed to have it shipped to me. But about 2 months ago a hydroponics store opened up here in town, and I can get it through him.
I had some radishes last night, just sprinkled some salt on them and ate them like that. They were very juicy and tasty, I may need to look up some recipes for them. I generally just eat them with salt, or in a salad. It will be interesting to see if yours have the same shape in only coco coir, but I have no doubt they will be tasty. Post pics if you can.
