I feel really dumb having to make this issue post, but I have been trying to figure this out for a couple of hours now, and also haven't been able to find an issue specifically about this.

I have AA, mystical ag, natura and pam's seed all working, but now I cannot plant the seeds that actually come with Agricraft???!?

Is there a repository with "official" or "semi-official" json files for various mod compatibilities where I can download the agricraft seed json files? It seems super odd that they aren't generating on their own, since these are the seeds that come with the mod itself, but maybe I'm missing something?

ok I've figured out that I wasn't using the right soil for some of the seeds, but I still cannot get the resource crops to plant on gravel soil. My guess is they aren't enabled by default, since it looks like the min-y, max-y for them is set to -2. K. I found the solution myself :P closing this.
