When we make rice, I put a cup a water in the 2 cups of rice and swish it around. Take the 1 cup of cloudy water out of the rice and stick it in a jar with a paper towel fastened (see pic)to the top. Let sit till you just smell a little sweet Sour. Could take a few days or a week depending on how warm it is. Then just dump milk in. (The proper ratio is supposedly 1 part rice wash water to 10 parts milk but I’ve done everything in between. Even 1 cup rice wash water to 2 cups milk. )
Doesn’t take long from this point just a couple days and it will separate a yellow/clear liquid from a cottage cheese like substance. The yellow/ clear liquid is the Labs.
This can be used on everything. For Gardening you can’t really go overboard except in foliar spraying. For watering in about 1tbsp per gallon is plenty, for foliar less than 1/2 tbsp per gallon but start out less.
I would search benefits of labs in the garden cuz I could go on all day.
Also make sure you feed the cheese to your pets. It’s like yogurt x1000
