I didn't fancy caring kilograms of soil, which I need to put my tomatoes in bigger containers! So, I bought just a small bag of soil plus a package of a potting substrate (peat free) made of coconut husk :) It is very simple to use. You just need to put some in a pot, add water and the substrate gets bigger within a minute - good fun! :)
