Paully, I've use some MG all purpose that you dissolve in water. The plant I've used them on were well rooted in cup and leaves were already turning dark from being in partial sunlight on the window sill. I've had no problem with them. Some of them are now outside in filtered sun and I'm still misting them. At present, I have another round of cuttings rooting, all of them duplicates. I have them in a shed instead of the house so the temps will vary a lot more and will be hotter in the daytime. I'm not worried about losing any of those so I will be experimenting with them by misting because they will probably dry out quicker. Good luck on yours. "gene"
