I'm growing some Matias Romero, how many grams could I expect from each jar (½ pint (~240ml)) ?

I'd like to know, once inoculation is done, (I'm using jars with metal lids), if I should put some scotch on the holes of the lids or jut leave them opened ? I also wonder if light is required or not just after inoculation ? Thanks for your answers.

hi, i don't know if the title was really clear ?? I leave in paris and i d like to grow shrooms, but i don't know what kind of jar should i use. I saw some jars in some internet guides, but o don't know if it's a special kind of jar or just a jam pot ??
