Feedback wanted on Aussie Gold Orchid Mix, PrimeAgra, and EpiWeb

[Becca]

Hi! I am currently using Aussie Gold Orchid mix for most of my orchids. All of my seedlings are in the fine mix, and I have a mature oncidium that is in the medium mix, although it probably should be in the fine mixture.Previously my oncidium was in bark and it did just fine. I switched upon recommendation of a local grower. I also have cymbidiums in the large mix. So I haven't seen much of a difference in the plants I have potted in the Aussie and the plants I have potted in bark. The seedlings in the Aussie seem to be more fungus prone for some reason. The company claims you cannot over water with their product, but I am wondering if that is true, not that I am trying to over water. If anyone has any experiences they would like to share I would really appreciate it. I am almost tempted to try EpiWeb or PrimeAgra, so if anyone has any experience with the EpiWeb or PrimeAgra and more specifically I would love to hear your opinion!
