Im going to grow in soil useing Just Right Xtra. It already has bacteria, fungi and enzymes in it. So I'm wondering if benificials like Voodoo Juice, Pirahna, Tarantula and sensizyme are needed or not?
Soil needs npk in some form. The amounts, if any, should be listed on the package. Fungi and bacteria simply break down the organic matter to make it available to the roots. So no, you don't need that extra stuff if the soil has enough already.
