As a side note.... I will say that I was told the "ropes" can handle (or even prefer) more moisture than your typical Hoya. When I complained that mine was beginning to resemble a plastic plant - no growth, no flower - it was suggested that I up the watering. Sure enough, I've gotten growth. I've also been told they prefer crowded pots.
That being said, everyone else here probably has much more experience than I do with Hoyas, I am a relative newbie in this area. And unless it's a bog plant, what doesn't appreciate good drainage?
Okay, so was this a useless post, or what????
