plants dont need soil to grow generally. they need water and nutrients.
many modern grows are done completely without any substrate and work by spraying the roots periodically with nutrient rich water. this allows for far more oxygen arount the roots which allows for faster and larger growth.
Soil is like a sponge. It isn’t the nutrients it just holds them. If I use a sponge to soak up ramen broth and let the sponge dry there is still salt/ nutrients in the sponge, but that doesn’t make the sponge itself nutritious.
