I have been growing a plant seriously for more than 3 years using every trick at my command trying to get it to flower; the plants name was Hoya desvoeuxensis. I finally had it growing in 3 different mediums and moved it from a 14 hour day to a 12 hour day and let it climb to the ceiling in my grow tent. It started to bud up, and I lost my first set of buds, but then a miracle happened and two different plants began to bud up; I was beyond happy; I was finally going to flower this pink, bell-shaped beauty!
