Mine is in a large clear plastic deli cup that I poked holes in, about an inch and a half up the sides. No holes in the bottom. I water it once a week in the winter, twice a week (sometimes more, if it is really hot) in the summer. Only feed once a week, either way. Once a month, I flush the cup by watering continuously for 5 minutes, no fertilizer. Mine seems to keep its buds/flowers, for the most part. If it gets a cold breeze though, off with the buds! I also have it on a heat mat, away from drafty areas.

I have one in a self watering pot from Walmart for over a year and it has only bloomed twice.I have my big one in a ceramic two piece pot self watering pot got from Big Lots...It has buds on now and tons of non active peduncles.I'm going to replant my smaller one into a net pot like some of my other hoyas.I thought self watering pots would be good for this hoya,but I'm not sure now.It was blooming much better when I first bought it at target around 10 years ago.There roots eventually rotted and i have the cuttings from it.I'm going to try a loose airy mix this time around.This hoya really likes to drop its buds a lot!The original container was peat based..so i may try half that and half pumice in the mix.I have a feeling that multiflora might like it a bit more acidic then others.

This is a pic of the deli cup and media:

A mix of 1/8 inch perlite, 1/8 inch Orchiata bark and a few shreds of New Zealand sphagnum moss.

Try growing it in hydroton. It will bloom its head off. And an observation made by one of our members here is that in hydroton, it keeps the flowers significantly longer. (It's been so long since I've grown mine in soil that I can't remember if I noticed this when I switched over...)
