Growing Hoya incrassata

I purchased a cutting of Hoya incrassata from a Florida vendor to fill out an order in the summer of 2015 and it flowered February of 2016 after only around 18 months.  It grows in my normal peat, bark, and perlite mix, and I keep it on the dry side.  It grew and flowered completely under artificial lighting.  Below is a photo of the entire plant:
