Lets look at how many "essence dust" this takes to make, though. 4 for every weak essence, 4 weak essence for every normal essence, 4 normal essence for every strong essence, and 4 strong essence for every extreme essence. So that's "only" 1024 essence dust for one strong essence. You need 4 of them for a crop that uses extreme essence, so that's 4096 for uranium seeds, right? Right... assuming you already have a master infusion stone. If not, it's a additional 8 for the starter one, four weak essence mimimum for the next tier, four normal essence for the next tier, four strong for the next tier... and if you want to do the whole thing in a non-automated manner without going insane, then it's 4 extreme essence for the next tier, aka the master infusion stone.
So lets calculate this from scratch. 4096 for the uranium seeds, 4096 for the infusion stone upgrades, and 8 for the first tier of infusion stone, clocking in at 8200 essence dust minimum.
Even with those occasional weak essence drops, it's a long ways coming.
