This mix can’t be used for seedlings or small clones. It will burn them up.
1/2 bag Fox Farms Ocean Forest
1/2 bag good natural bedding soil with no nutrients but balanced for pH
2 gallons Coco coir
1lb azomite dust
1lb dry humic acid/ bacillus mix from Grow store
2 gallons perlite
2 cups vermiculite
1 gallon worm castings
2 gallons mushroom compost.
With this soil you don’t need to feed nutrients until 6 weeks or later. It has given me good results. Add worm castings to your depleted soil and use it for seedlings.
