GROW!T coco coir products are a great option for indoor or outdoor grow media. They manufacture premium coco caps, that range in size from 4"-6".
I just ordered 2 of these 25lb bags TO MY DOOR from HTG. Only cost $143. Why are the clowns at HB charging 3x pricing? I'll have to ask advanced Nutrients if they know about it.
Not the best, but it works well for some personal. I've had this for a few years and still works.
