Hoya curtisii Flowers At Less Than One Year Old!

I used to think that Hoya curtisii had to get some age on it before it would grace you with flowers. My first plant took 3-4 years and a lot of work chasing the sun before I got my first flower. This Hoya was purchased as a bunch of cuttings rooted in a pot from Lowes back in early May and has now flowered at the bottom of a 3 1/2 foot vine. It is a plant that grows in my warm humid grow tent under nothing but artificial light.
