iTrader Positive Rating: 100% | Re: How-To: Mineralized Soil Substrate, by Aaron Talbot Shouldn't feel like fiber. Grainy as in sandy, is exactly correct.
Are you possibly using organic soil, potting soil, something like that? Fibrous is not what I think of when thinking of cheap topsoil, and cheap topsoil is what you should be mineralizing - the absolute cheapest bag you can find, the $1.50 kind of bag.
I've never seen any molding, but white mold makes sense with every high fiber content mix, it'd be the wood. Feeling like fiber sounds like there is an awfully high wood chip/pulp content in the topsoil you are using, which is why I ask what the beginning product was.
I sift the soil at the end, and remove all the little wood chips and such - what I end up with after sifting feels like ashes almost, super fine, dust. |
