How it it perfectly normal for a rootlet to come out of the earth/medium ? I have never seen this before? And I know its normal for the rootlet to gooseneck down into the soil, but out of the soil is unnatural do to the fact it would die outside of the soil in harsh condition like dryness, air, and light.
You are absolutely right! thats why that is not what happened. It seems that we are interpreting what the poster said somewhat differently, that is all. What the poster is calling the "root" i believe is actually the "stem" which to an inexperienced grower would be easy to confuse with the root. because it looks JUST LIKE THE ROOT, and in fact is the root but its the above ground portion of it, and will turn into the actual stem.
I came to this conclusion because it would be IMPOSSIBLE for the actual "root" to escape the soil and end up "above" the leaves
Does this make sense now?
To me what the poster described (albeit poorly) is perfectly natural and happens EVERY time. Perhaps we will never know without a picture.
