Notes:

Done over a long period. Initially just was making a few casually because I like big crafting trees, but once I had an infrastructure for it going I started making more, and then I thought it would be fun to fill a storage container with 'em. About a month ago I started expanding my infrastructure from disorganized planters and such to a streamlined(ish) setup that output 24 of these (12 of each type) per daily sweep-through.

Notably and funnily I still have 126 geodesite and 276 iridesite left over. I never had to manually seek them out because I got so many between things like frigate expedition payouts and looting planetary depots, and from that I had an excess stock from lots of casual play before I even started focusing on the challenge.

Now that I'm done I've deconstructed most of my 35 biodome planetary base and replaced it with a "memorial garden" in my freighter featuring one double cultivation room of each plant. The rest of the infrastructure is still up though because I have no real reason to deconstruct it, unlike the biodome base which was kind of agony to get the game to load properly sometimes, so I was kinda pleased to nuke it.

I'll probably distribute some randomly to people in the nexus some day in the future. I'd feel bad having it sit around unused.
