Is Lime Sulfur an alternative to Cheshunt compound?

[Brendo]

Hey guys,

I've just sewn a dozen Peruvian Torch seeds in a mixture is 1/3 cacti & succulent mix, 1/3 perlite & 1/3 washed river sand. I read Cheshunt compound is great for preventing mould in the nice, warm, moist soil.
However I can't find anyone who's even heard of Cheshunt, let alone sells it. Google tells me it's a small town in Victoria, Australia

Anyway, the same tek explained that sulfur is a suitable alternative. My local garden supply store only sells lime soda though; will this be okay?

Thanks in advance fellow Psychonauts!
