Why dont you just put it by a window / put some lights under it..

Also.
Train the plant, bend the stem / tie it down, to make it grow slower + bushy.

Your aim :

Make it grow sideways not up

I have one as a house plant, for 4 years now, hasnt flowered, and it in the corner of my room and gets its light from the many windows.

BUT i get alot of yellow leaves :P
