I have a supplement for use in horticulture. It is a powder that contains mostly subtilis with smaller amounts of a few other strains.
Prior to horticultural application I would like to "multiply" them so as to get to most out of the product.
Is water and a drop of molasses sufficient? (that seems to be accepted in cannabis culture)
How fast do these guys replicate? Without high tech lab equipment is there anyway I can tell that they are in fact multiplying?
