How To Make Fermented Brown Rice Water For Plants

An Easy KNF Recipe: Fermented Brown Rice Water
Fermented brown rice water only takes around a week to complete.
Ingredients Needed:
- Brown Rice
- Milk
- Water
How To Make:
Step 1. Rice and Water
- Just like when cooking rice for eating, use 2 parts to 1 of water and rice.
Step 2. Soak
- Soak the rice for 3 to 5 days without covering.
Don’t wash the rice.
Take the rice and put it directly into the water. Then put it away in an area without sunlight that is not too cold or else it won’t ferment or will ferment very slowly and might not be as effective. Use a clay container or a glass container. Plastic is best not to use for the fermented bio liquids.
Step 3. Throw Out The Rice
- Next, strain off the rice and keep the water (throw out the rice.. chickens love it). This is what you will be using.
Step 4. Add Milk
- Next, add milk at a 1:10 ratio. So for 10L of rice water, use 1L milk. Then, cover the container with a thin breathable sheet.
- You can use pasteurized milk, it provides enough lactic acid that helps the targeted bacterias grow.
- Store away the brown rice water with the milk for another 7 days, then the ferment will be complete.
Step 5. Storage
- It will stay good for up to 1 year if you store it in an airtight container.
The last time I made fermented brown rice water I used my wife’s breast milk for the milk part (we had some in the fridge that was past the date for giving it to our baby. Normally I’d give it to the puppies or dogs, but this milk went to the brown rice water and worked perfectly.
How To Use Brown Rice Water
Use it to soak seeds for an hour before planting.
Use it alongside Liquid Herb Hormone in a 1:1 ratio.
Use it with Liquid Herb Hormone & Fermented Plant Juice in a 1:1:1 ratio PLUS water (up to 500 to 1,000 times)
It can be used to prep the soil before planting, for cleaning the seeds (soaking), for ensuring budding flowers and sprouts grow stronger and faster, as a natural insecticide, and as a weekly treatment to help support healthy plant growth overall.
Dilution Guide
Dilute 500 times for seedlings
Dilute 500 times for seed soaking
Dilute 200 times (and mix with fermented liquid calcium 1 part to 1,000) then spray on nightshades to prevent and cure bacterial disease.
