I am trying to propagate some trees from cutting for use as bosai material and I would like to know what soil or meduim is the best to use.
Nice question for the food category. Anyway, rice and flour won't get you the desired results. They both will absorb water like vermiculite, but are less willing to give up the moisture when needed. Plus they could change the soils acidity. Your best bet is to stick with the proportions that were given to you so you can enjoy the best crop
