Watering: When the top 2 inches of soil is dry before watering, they do not require constant watering. If you use a moisture meter, water when the meter reads 3 or less to water. Water thoroughly until it drips out the drainage hole(s). Moisten the soil and do not make it soggy. Avoid overwatering as this will cause root rot and plant death. Cut back on watering during the winter months

Lighting: Bright indirect light. Near east or south-facing window is ideal

Soil: Use well-draining mix that allows excess water to drain off easily and provide air circulation to the roots. An airy mixture of peat moss, perlite and pine bark is ideal

Temperature and Humidity: 60-85 degrees is ideal

Humidity around 50%

Extra Tips: You do not need to re-pot often due to its small root system, typically it will take 3-5 years to repot into a pot 1-2 inches bigger unless there are issues that arise such as infected soil, waterlogged soil, or pest that cause it to need to be repotted sooner. You may need to prune the plant back if you think it is getting too big or growing too long, you can take the pruned pieces and propagate them in water very easily. Provided a trellis for it to climb. 

Pet Toxicity:  Hoyas are safe for all humans and pets
