For this grow I'm planning on using two different types of soil mixes combined, plus some perlite.
The one soil mix has an NPK of 0.5 - 0.5 - 0.5 and is made using compost and worm castings. The other soil mix is made using mycorrhizae and doesn't have any NPK factor. Should I just use the latter soil or would the compost mix be beneficial?
I'm going to assume that adding perlite to a substrate wouldn't be good for little baby roots to grow through?
