I do have to say i started using it before i started growing anything except my succulent type plants.Some Hoya's,Rhipsalis etc.. The plants that i see the biggest difference in are my foliage plants.Lipstick plants,Hoya's,Epi's,Prayer plant,peace lily's and my many Holiday cactus.It did do well on my Capitella 'Campfire' and my pencil cactus.
Hoya 'Chelsea'
That's H.'Chelsea' in the middle now.
Above her is H.'Compacta' to the right H. 'wayetii', up higher on the left is a Rhipsalis 'sulcata',the 2 on the left edge are both H. Carnosa's 'KQ' & 'KP'.
As far as thick leaf succulent i have just started growing them so i don't really know except i do mist with it in the water anything i'm propagating.It does help bring plants back that are struggling.I started out with house plants and i will be learning what it will do for succulents along with all yall.
