Greetings.

I was wondering if anyone here could reccomend some mods?
We're limited to 1.7.10 sadly.
I'm looking for mods which will make living in bases underground difficult or impossible.

Some things we've already looked at:

• Decreased air quality underground: (Using Immersive Engineering machines underground generates smoke/dust which needs extractors to the surface)
  • Ecology mod (On a chunk basis, not just underground/per space)
  • EnviroMine Air quality (Adds lots of extra stuff)
  • Pollution of the realms(Perfect, just not at 1.7.10)
• Having the only power source be solar panels: (Using another mod for solar power, removing all normal sources of power from IE)
  • Solar flux
  • Solar Expansion
• Bukkit:
  • Made crops only grow in daylight

If you know any mods that would fit into either category, I would really welcome your suggestions :)
