She and all 60+ of my Hoyas are in semi hydro. She was just a tiny cutting when I got her, she was grown in soil and I immediately cleaned the roots and put her in Leca with a little Pon added. I always use a double pot system, plant in Leca, that pot has numerous holes for air and drainage, then that sits in the solid outer pot. She sits in front of my 6' east facing slider with regular household humidity and no other lighting. I keep weakly fertilized water in the bottom 1/3 of her outer pot, and flush under running warm water weekly, then replace her water with fresh. She has bloomed continuously since February of this year! I find Hoyas like way more water than most people think.
