Is there a specific kind of molasses you buy to mix in with water when watering your plants? I know the answer is on this site somewhere but i cant find it.
It's what most folks here are using. Same thing. Blackstrap is a processing step and perhaps a teeny, teeny bit rawer.
You're fine. 1TB per gallon's what I use.
Helps build beneficial microbes in the soil to help break down organic matter into nutrients usable by plants. Using it often is unwise as it can attract bugs. You have to be sure to use only organic ferts as chemical will just kill the microbes and defeat the purpose.
