Well I guess Hoyas are totally unpredictable.  I was completely wrong on thinking most of these buds would abort.  I have a theory that I have developed on why this batch of buds hung on when I have literally lost dozens in the past.  I am developing a video called Hoya lasiantha – The Final Word that should be up soon explaining my theory.  You can take it for what it is worth, which is probably not much:)
