Mixing a soil

What would the ideal soil mix be with the followong?

canadian spagnum moss

perlite/vermaculite

bat guano 15-1-0 ( i think, i know there was almost no k and p and that the nitrogen was over 10)

Earthworm castings

Bone meal 3-15-1 (again may not be exact but thats a good guess)


So what ratio's should i mix? Anything else to add? What about the soil i dug out of the ground? Its a little clay-ey but its not that bad...

ok, well don't use sphagnum moss... here's why: http://www.ext.vt.edu/departments/envirohort/articles/misc/sphagnum.html. do you mean peat moss?

you don't really have a base soil here. i would go with a fox farm soil/perlite/vermiculite/earthworm castings.

my soil mix is 3 gallons fox farm ocean forest, 2 cups vermiculite, 1 cup perlite, 1 tablespoon mexican bat guano (10-2-1). don't use that bone meal until you get to the flowering stage. it's high in phosphorus and unnecessary during veg. i would shy away from using outdoor soils in indoor grows. it can bring in unwanted pests.

ok well i know a lot of soils are 50% spagnum peat moss (which is what i have) so i should be alright i think. Also, im growing outdoors. Does anyone know how many cups of bat guano are in a pound?

ah, i stand corrected. sphagnum moss and sphagnum peat moss are different things. good job. still peat moss is airy as hell, i would get a bit heavier soil and mix the rest of your stuff in.

you can't convert cups to pounds because that's a volume measurement and a weight measurement. so one cup of steel ball bearings may be one pound, but one cup of peat moss will be way less. you can go cups to gallons which is 16 cups to a gallon.
