Hoya davidcumingii is still never without flower and growing strong two years after converting it to semi-hydroponics. Couldn’t keep this one going in soil no matter what I did. Now in S-H grows like a weed. I water this plant once or twice a day (yes that is day and not week) and keep it in the warm, humid plant room. I have recently started more cuttings in s-h that have not made it using conventional methods. I will report on their progess as they begin to take hold. Here is hoya davidcumingii from this week.
