Interesting discussion of potting mediums. Many times it is dependent on what is locally available. Main thing is something that drains quickly. Those roots are beautiful. As Ron said, once the bulblet has good roots it can be separated from the parent Or leave it with the big bulb and eventually get a clump. Though Ron, I remember when you left the clump to fill up the pot, you had a difficult time separating out the different bulbs. I personally would never cut roots when I repot. Any wound is just another point for infection. Some people dust the roots and basal plate with ground cinnamon as a natural antiseptic. On the other hand, I heard someplace (I don't remember where or from whom) that too much cinnamon acts to retard the production of new roots. So I say, whatever works for you.
