After five plus years of growing Hoya sp. MT-02 without getting a peduncle, I started watering the plant with reverse osmosis water, which takes out all of the water hardness, and makes it as close to rain water as you can get. One day while tending the plants in the grow-tent I moved a vine and looked at Hoya sp. MT-02, and I almost fell over when I noticed a peduncle that was not only growing, but budding up. At first I did not believe that the peduncle even belonged to the plant as I was resigned to never flowering this Hoya, but after following the vine 3 times, I finally realized it really belonged to MT-02!
