That’s really good soil…mine is nothing like that, it is organic, but certainly with a lower percentage of the good stuff that is on the list.
My store has pure worm waste and bat guano concentrates that I will most likely get.
I don’t have the bag, but the store owner said that I will need very little nutrients to add.
I don’t know if it means anything to anyone outside of France, but it’s called “Batmix” and “Royalmix”.
Found it on google: (pitch if anyone interested in reading)
Bat mix Plagron
Soil with fertilizer, culture support NFU 44-551. Basically, Plagron Bat-mix is composed of the best selected peat with the greatest care.
The addition of various types of fibers and perlite allows you to obtain a lightness and a level of oxygen that you will only find with Plagron quality potting soil. The unique, large-scale presence of vermicompost ensures high quality biological activity and even better water absorption. Bat manure (Bat-guano) is the most important nutrient added to Bat-mix Plagron.
Naturally rich in phosphorus and potassium, bat manure guarantees a particularly exuberant flowering. Plagron Bat-mix contains enough nutrients to provide for the plant during a complete cycle. It is only under perfectly controlled conditions that bat manure can be processed to obtain the quality product from which the Plagron mix is derived.
Warning ! Add water before use. Do not add fertilizer during the first 6 weeks.
Sorry for the long post
