How I Grow Hoya sp. aff erythrostemma IML 1423

This plant whose flower reminds me so much of H. mindorensis has flown underneath my radar for some time.  It has never done too much up until now.  It has always grown under artificial lighting with good humidity.  It is one of the few plants that I have left growing in a clear container which I am no fan of, and perhaps this is the reason that it took so long to flower.  I had it outside this past summer, and when I returned it to its grow tent home it decided to flower on two peduncles.Hoya sp.  aff  erythrostemma IML 1423 102014b
