Mystery Dragon Fruit Growth

I brought my tropicals indoors on October 17. Most times, my plants don't grow well indoors despite being in front of a south-facing window. I decided to ditch my 5000K lights and get 6500K lights. I also placed more lights on each plant. As a result, my mystery dragon fruit plant has grown greatly even though it is indoors. Below is a before-and-after picture on 10/17 and 11/24.
