What vegetables do you grow?

[Annies]

I love to grow Tomatoes, white chillies,Broad Beans,Clove beans, Eddo plants, Spinach, and some other Vegetables as long as they fit in my garden.

I'm trying to grow spinach for the first time. I bought a perlite and coir seed rising mix. I have a question, In what proportions should it be mixed? And do you have any advice?
