Care level: easy
Ideal temperature: 68-85°F / 20-27°C.
Humidity: 45% and above.
Light: Bright, mainly indirect light.
Sun Exposure: In the northern hemisphere, south, east, or west-facing rooms. North-facing windows may not provide enough light for bloom initiation.
Soil: Potting mix with quick drainage that can provide good air circulation. Hoya RHM 14-1 can withstand a little dryness between waterings but don’t let it go too long as the leaves are fairly thin. Potting mixes that retain too much moisture for too long will rot the roots. Typical Hoya mixes contain perlite, orchid bark, cactus and succulent potting mix, coco coir, or sand among other ingredients but dense substrates like peat are used in moderation to prevent too much moisture retention. Unless of course you go semi-hydro. I’m not here to tell you what to do. I grow these babies in PON.
