I am loving Lignumus and found this mod via the Lignumus director's cut. Thank you, @SafTheLamb, for such a creative and fun extension! Wood on Vulkanus is a silly and fun idea, and the spoilage mechanic from Gleba deserves more usage like this and is not nearly the PITA it is on Gleba within the context of this mod.
The thing I use it for for sure is to make wood for all the Lignumus recipes. With Lignumus, you cannot make belts or assemblers without going through a wood phase, and that rule applies on every planet, not just the main planet the mod adds. It's very useful to combine it with sulfuric bacteria cultivation, put the overflow into provider chests, and then have wood once the bacteria finishes spoiling.
Sulfuric melting is also very cool, once you remember that you can use lava to void things even if you don't have recyclers unlocked. Sulfuric melting produces most of the harvested resources from the planet, and you can always use priority spliters to throw away what you don't need into the nearest lava pit. It is not a practical problem given how long mines normally last, but it's neat that sulfuric production is self-sustaining and can be ramped up pretty far with copy-paste.
Thanks all around. Funny note: I started this post to ask what people do about overflow from the sulfuric melting recipe, but I thought of an answer while typing it up. Perhaps others are at some point on that same journey, so I thought I'd post it anyway. For those who find this all very obvious, well, please be gentle.
