Greetings. Looks like no specific trees were mentioned, so would need this information and stages of development to know for sure.
That said likely will work fine.
Also likely it would be better to just get the components in from US suppliers and mix ones own media.
This way one can make different mixes as needed for different species and stages of development
In addition, one should strongly consider properly recycling the media, adding more akadama as needed after recycling. This will not only save money, which doesn’t seems to be an issue in this case, but also is better for the environment.
Cheers
