Here are two very good organic soiless mixes...
LC’s Soiless Mix #1:
5 parts Canadian Spaghnam Peat or Coir or Pro-Moss
3 parts perlite
2 parts wormcastings or mushroom compost or home made compost
Powdered dolomite lime @ 2 tablespoons per gallon or 1 cup per cubic foot of the soiless mix.
Or, if you use Pro Mix or Sunshine Mix...
LC's Soiless Mix #2:
6 parts Pro Mix BX or HP / Sunshine Mix (any flavor from #1 up)
2 parts perlite
2 parts earthworm castings
Powdered 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.
And a new addition: 1/3
Fox Farm Ocean Forest (or 50/50 OF/
Happy Frog), 1/3 Coco Fiber, 1/3 Perlite. Feed with teas or PBP. Holy crap the results are amazing!
