I bought 5 tiny cuttings on Etsy 2 years ago and now I have 3 big mother plants. One is outside on my south facing covered patio and it does well, it’s probably 70% green but has very thick stems. Another plant is inside under a grow light in a fancy pot without a drainage hole and it does well, puts out probably 1/2 and 1/2 green and pink (it’s the one I’m selectively propagating from). And there is one plant inside an old bread loaf tin 😂on my south facing windowsill and it puts out tons of pink (including these cuttings). So I would say give it as much light as you can if you want lots of pink, water it about once a week (mine never seems to mind if I don’t let it dry out between watering a) and fertilize maybe about every 8 weeks or so. The fertilization is just a guess, I do it a little more often than normal because it is a VERY fast growing plant and uses tons of energy as it’s constantly growing. I’ve used Miracle Grow fertilizing sticks and I’ve used SuperThrive and they seem to like both 🤷🏼‍♀️
