super soil

Any one have opinions or knowledge of using composting super soil I have a recipe for some but woundering if it worth it would like to see pics of bud actually grown in some thanks for help

I've heard so many different opinions on this. I've been told when using "Super Soil" you will not need to feed your plants, no need to flush the soil, no need to monitor the PH. Just water and watch it grow. How true are these statements?
