Maybe Ill try this mix
LC's Soiless Mix #2:
6 parts Pro Mix BX or HP / Sunshine Mix (any flavor from #1 up) / Fox Farm Ocean Forest or Light Warrior
2 parts perlite
2 parts earthworm castings
Powdered (NOT PELLETIZED) dolomite lime @ 2 tablespoons per gallon or 1 cup per cubic foot of the soiless mix.
If you use a 3 qt. saucepan as “parts” in the amounts given above, it equals about 1 cu. ft. of soiless mix and you can just dump in a cup of powdered dolomite lime.
But, a "part" can be anything from a tablespoon to a five gallon bucket. Just use the same item for all of the "parts".
