You could try seed selling companies on the internet. BOONDIE SEEDS - put mustard greens in the search box.

I just had a look at my favourite seed supplier. They do have a table green mustard list of plants, but there is also this one under the Green manure section that is also mustard greens mix. I've tagged the page it's on so you can have a look at all the green manure seeds they have. https://www.thelostseed.com.au/seed/green-manure/

It says 35-60 cm apart. I would suggest plants 40-50 cm between them and rows 40-50cm apart.

You should grow white mustard if your planning to make the condiment. Other varieties are grown more for leaf.
