These two soils are very light, with perlite and some NPK for 2 weeks. However I didn't see if these two has some minerals in it (iron, magnesium, calcium, boron...). Anyone know?
If they don't have any minerals, I guess it's okay to reuse soil for second grow? Of course with some flush at the end and removing old roots.
