Best non-dusty substrate
There have been many posts about the best substrate over the years but I thought I would do a quick census to get a feel of current thinking. One of my hams succumbed to a respiratory issue and I suspect that the substrate was a factor. It was Carefresh which I have used in the past without any problems but was beginning to think it was quite dusty. So, my question to all is: what is your favourite non-dusty substrate?
