I have an update on my Hoya serpens seedlings and seed sowing experiment. Here you see one of my seedlings that was planted as a seed in an Aerogarden. I also planted a number of seeds two weeks later the conventional way in soil. The seedlings recently had started to yellow in the Aerogarden. My guess is that the medium would just stay too wet for slow growing Hoya seedlings. The good news is that I transplanted the seedlings out of their too wet home into a conventional mix, and they are already starting to improve. It was a fun experiment and I will have a video out in the future documenting the entire project. Now I can plant an herb garden in my Aerogarden!
