TL;DR
Allow producing Holmium solution in one of the advanced chem plant buildings; the Cryogenic Plant or the Biochamber.What?
Holmium Solution can currently only be made in a chemical plant. This means that accomplishments on other planets can't be used to bolster your production on Fulgora.I propose that one of the advanced buildings attainable on other planets becomes capable of creating Holmium solution, to be able to benefit from either the increased productivity of the Biochamber, or the increased module slots of the cryogenic plant.
Why?
Planets usually have interactions with tech of other planets which can benefit them. For Fulgora, this is currently the Foundry, which can make Holmium plates.However, the bottleneck remains the solution itself, as a fluid. An additional synergy with Gleba and/or Aquilo would be quite appreciated in this case.
