Is it possible to make a rooting gel if you buy the active ingredients? I don't want something that won't store well. I don't want to use gelatin or other things from around the house with short shelf life. I was hoping to buy the active ingredients and a gelling agent.

I don't know what amounts and what to get though. I'd also like to add a fungicide.

I used to get great results with Wilson's Roots but I can't seem to find it for a reasonable price that ships to the USA.

I can't find another rooting gel with fungicide. :/
