Hi, I was wondering if you could add Niter and Sulfur from Thermal Expansion as a crop if possible (And maybe Railcraft Saltpeter which is pretty much Niter) , Maybe as a tier 3 or tier 4 crop? Specifically Niter, As I find it very difficult to collect without having to pulverize a lot of materials to get any decent amount.

Thanks! and continue with this amazing mod :)
