Whats everyones favorite/most successful medium for propagating Hoya’s from stem cuttings? (Krimson Queen specifically) I’ve only ever used water for all my plants and have zero issues with any type I’ve done. Right now I have a Hoya Chelsea that I started a month ago and its started to show the TINIEST roots. Now I know 4 weeks is an average time, I’ve just never had any of my plants take that long to show any signs of life…and I’m impatient LOL Also, grow light? Or window?
