Not exactly the same, but this mod is compatible with 1.6 and will suffice for now. https://www.nexusmods.com/stardewvalley/mods/21000 Check this list for updates on 1.6 ports of aedenthorn mods https://smapi.io/mods
I honestly don't know why this is more popular. never got "better quality" mods to work properly since 1.3 this just plain works with everything i tried. both versions of ppja mods included.
ok so... automation is to blame. i did a bunch of testing and got mixed results between save files, but the problem was that i was using automate to automatically use the seedmaker. i assume that this is because the mod only loads the code when interacting with the seedmaker.

Any other seed maker mod (like BetterQualityMoreSeeds) might conflict with this mod won't work together.
