Indoor Soil Mix

[Norman]

Hi everyone,

I have a quetion regarding soil mix. In my country we do not have a great selection of organic soils so I decided to create my own mixture for my first indoor grow. I ve read that a good mixture would be:

3 parts peat moss
3 parts compost
2 parts perlite
1 part vermiculate

What are your opinions? And what is the best NPK ration for soil besides the PH??

Thanks.
