If u are doin this indoor and have alot of soil to mix a kiddie works very well otherwise u can use lage storage totes. After mixing ingredients wet soil and mix it thoughly and let it sit for about a week or 2 then its good to go for planting. Keep in mind with this mix u should use a good organic fertilizer at about 1/2str. or an organic tea. I use BioCanna and budswel in a tea 3rd week of flowering and they really seem to get fat.
Base Soil Mix-
1-1.5 parts perlite(large chunky if poss.)
2 parts peat or coco
1part compost (make sure to a well composted material like mushroom compost)
.5part wormcastings
1 1/2cup of of fine dolomite lime per cubic feet of soil(1 ounce per gallon)
Optionals (good stuff)
epsom salts
greensand
crushed oystershell
aragonite
soil innoculants like myco fungus and soil bacterias

Now just add the corosponding ingredients to the stage of growth ur at to ur base soil mix.
Seedling/Clone soil-
i only add .5 parts of vermiculite to help hold a little extra moisture

Veg soil-
.5-1 c. bloodmeal per gallon
1/8C kelpmeal per gallon

Bloom soil-
.5-1c. sul-po-mag or rock phospate per gallon
.5-1c. bonemeal per gallon

1 cubic foot = 6.4285 US dry gallons
