Care level: easy
Ideal temperature: 68-85°F / 20-27°C.
Humidity: 50% and above.
Light: Bright, indirect light. A little full sun is okay with acclimation.
Sun Exposure: In the northern hemisphere, south, east, or west-facing rooms. Doesn’t want hours of direct sun. North-facing windows will not provide enough light for bloom initiation.
Soil: Potting mix with quick drainage that can provide good air circulation. Hoya heuschkeliana outer variegated won’t want to be left too dry between waterings and will always prefer higher humidity. Typical Hoya mixes contain perlite, orchid bark, cactus and succulent potting mix, coco coir, 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.
