Thanks for this pack! It has been a great way to check out some mods like Minechem and Galacticraft that I've seen in passing before and thought they were cool but never really dug into them.
For what it's worth, I also had to break and then set back my Chemical Decomposers after upgrading to 1.4.8 (think it has to do with a change in their buffer size?)
I have a cobble gen -> stone barrel -> lava -> obsidian -> Chemical Decomposer -> Gravel from the Silicon Dioxide -> auto-sifter set up going and it is slowly giving me hope that I can get the materials I need to making all the stuff the quest books calls for, especially the iron. Thanks for that great post on page 21 here in this thread!
I'm working on the Galacticraft questline and I'm hung up on the Thermal Padding set. What's a good way to get wool? I can do Ex Nihilo silk worms on trees to get string and use string to make the wool, but I'm estimating a stack and a half of wool so that'd be 6 stacks of string and that seems like it would take a while. Especially since this is a MineChem heavy pack I figured making the wool that way would be better, but I am having a hard time getting the Nitrogen I need.
tl;dr question: What's a good way to get lots of Nitrogen? (Before being able to farm Skeletons in a spawner for their arrows and presumably without chickens because I haven't seen any eggs nor spawn eggs for them so thus no feathers.)
