i shall give my warning. make sure you research how much compost to mix with how much soil. I burn the shit out of my plants by using the wrong compost too. dont use chicken manure. it is Way to strong for cannabis.

and if you are talking about using peanut shells and barkchips as your compost they wont do much good. i't sjust a filler. you should try to get your hands on some composted worm castings.
