Cool thing about lab grown EM1 is it's diverse yet constistently probiotic. Lactoserum focuses on native cultures and exclusively lactobacilli.
Here's EM1:
Specifications
ACTIVE INGREDIENTS*:
Microorganisms: 1 million colony forming units/cc (units/ml), 1%: Lactic Acid Bacteria, Yeast, and Photosynthetic Bacteria
INACTIVE INGREDIENTS:
96% Water and 3% Molasses
*Not all microbes are listed on the actual label.
Just for your own sanitation's sake, the rice wash should be used up in a week. The bacteria will shift powers to a less active culture and begin to spoil. Starting with a lab grown culture is much healthier. You'd need a compound microscope to faithfully say you're culturing only probiotics. A liter of lab grown EM1 can make 33.3 high quality liters of EMextended.
2016Price of EM1 23$ without shipping. So 30$ with shipping
30÷33=91 cents per bottle
A gallon of agricultural grade molasses is 5-20$ store to store. And will feed 135 liter size bottles of EMextended.
So, lets pretend like molasses was $20.
20÷135=15cents per bottle
$1.06 per liter of lab quality EM1.
Ps i respect your devotion to DIY haha. I made a rolling trash can of bokashi and am still using it. In fact, it's going past expiration after july... i've used about half so far. I'll probably compost whatever's left.
