What is OHN?

OHN is made from popular oriental herbs such as Angelica Acutiloba,  Glycyrrhiza Uralensis (licorice), Cinnamomum Ioureirii (cinnamon). 

They are common at Chinese drug stores. The ingredients are not boiled as is common in Oriental medical practice, but fermented so as to maintain their lively power. 

OHN is a very important input in Natural Farming. 

In combination with other inputs (FPJ and BRV) it will wipe out powdery mildew and downy mildew when sprayed on leaves. It will also make seeds stronger. 

Spraying the plants every 7-10 days will make plants strong.

How to use OHN

OHN makes crops healthy. It is used throughout the early vegetative stage (Ian: As I understand it this is when the plant is growing from a seedling towards maturity), the vegetative changover (Ian: plant puberty I think) and fruiting stages (Ian: No explanation required).  The basic dilution (Ian: which I would take to mean add a small amount to a large quantity of water)  is 500-1ooo.

When crops are weak, mix apply Fermented Plant Juice (FPJ) at dilution 500,  BRV (which I take to mean brown rice vinegar) at dilution 500 and OHN at 1000. When plants have soft rot or anthracnose add water soluble calcium (WCA 1000) to this solution.

How to make OHN

1. Prepare Angelica Acutiloba, cinnamon bark, licorice, garlic and ginger to this ratio: 2:1:1:1:1. The garlic and the ginger are supplementary ingredients.

2. The three main ingredients are sold in a dry state. Put the three main ingredients in three separate jars and fill up to the 2/3 level with rice wine (or beer) so that they are completely soaked. The amount of rice should be such that if fully wets the ingredients but not too much. Let it absorb moisture for 1-2 days.

3. The garlic and ginger don’t require this wetting process. Just crush them and put them in separate jars. Then wait 12 hours.

4. Add an amount of brown sugar to the five jars equal to the weight of the ingredients, i.e  weight of brown sugar = plants and rice wine combined.

5. Cover the jars with porous paper and tie the paper down with a rubber band. Leave the jars to ferment for 4-5 days.

6. After fermentation pour distilled liquor into the remaining 1/3 of all five jars. Then stir with a stick.  The essence can be extracted five times.

7.  For long storage the lid must be sealed tight with no air passing through.

8. Stir each morning.

9. Combine the juice from the five jars according to this ratio 2:1:1:1:1.

OHN is a fermented herbal extract which is alive with effective indigenous microorganisms beneficial for organic gardens. Why do we use OHN? One can use certain organic materials fermented down and then use them as nutrients and plant antibiotics for many diseases and even used as an organic pesticide. Neem oil is a type of OHN, Pest Out is a garlic based Over the Counter OHN, and I will focus for cannabis on using a garlic and coriander based OHN combination. Now remember OHN should be fed to the soil and used in a follicular feed regimen. There are many recipes, so here are some I find to have good effects. I was once told by a great farmer that a true organic farmer uses anything in ones environment to create what is needed. If you have a good healthy strong plant that is pest & disease resistant, one can adhere some of those characteristics and beneficial indigenous microorganisms through a fermenting process and then administered to create new plant antibiotics and sheens. Not to mention the waste off beneficial microorganisms is an ammoniacal nitrogen, again Root Excelarator. So here are some of the recipes I work with, but feel free to use ingredients that are in your environment. Only use it on 1 plant at first to record plant reactions over a week period to see if you have created a good OHN.


Quick easy 10 chili garlic:

1 good sized jar
1 oz. Organic natural soap
10-20 Hawaiian chili’s
3 bunches fresh garlic


1. Chop peppers and garlic
2. Add all ingredients into jar and add water till 1/4 left of air, close jar tight
3. Steep for 10 days, shake twice a day
4. Add to sprayer at a ratio of 1:10 water
*optional: I some times add this to my neem when I am having white fly and spider might infestations. If you mix 2 tbsp neem per gallon water, cut it back by half and add 1 tbsp of garlic chili OHN.


Beer and dried ferment

Ingredients: (2:1:1:1:1)
Chinese Angelica root
Brown sugar
80-100 oz Malt beer
Gin or vodka
Five good sized jars for fermenting
Paper towels
Neem tree
Chili peppers
1. Soak all dry( Angelica, cinnamon, licorice) ingredients with beer and let sit for 24-48 hours in jars until all the beer us soaked into dry, do not drown ingredients, only want to rehydrate.(only fill jars 1/3)
2. Cut and dice fresh garlic and Ginger, leave all the skin on it Is teeming with EM( fill the fresh ingredient jars all the way to the top as they will loose mass in fermenting)
3. Now we add raw brown sugar, and mix and couture all ingredients and return to their separate jars cover tops with paper towel and use a rubber band to hold in place. Let sit for a minimal 7-10 days and if you like longer.
4. Now squeeze & drain all liquid off(decant) this will be done at least five times,first run is good to mix with animal feed, 2,3,4,5 are all good to feed your crops.
5. Now add chopped chili peppers and chrysanthemums and replace the same amount if liquid recanted off and ferment another 5-7 days, dilute these solution by a ratio of OHN 1:20 non-chlorinated water.
6. Follicular feed or add to nutrients or just water to soil.

Fruit Swipe Ferment

Rip fruit( mango, banana, papaya, strawberries…..)
* stay away from high citrus like lemons, limes, pineapple, oranges… Only feed these ferments in the finish before flush.
Brown sugar
Non chlorinated water


1. Mash and coat ripened fruit with brown sugar let ferment for at least a minimal 14 days.
2. Blend ferment liquid
3. Let ferment 3 more days.
4. Follicular feed dilute 1:30 and spray once weekly


Garlic and Ginger gin OHN

Chili pepper
*optional to add neem or coriander, I have even heard of chrysanthemum flower for natural pyrethrum
Large jars


1. Cut and chop garlic and Ginger put in separate jars
2. Fill jar with gin now half way let sit for minimal 7-14 days and decant
3. Decant, then add chili pepper and chrysanthemums add new gin runs 2,3,4,5 are good for pesticide spray. Dilute 1:20. 


Homemade Margold Calendula Spray

Organically repels chewing and leaf cutting insects

This homemade pesticide is super easy to make, and repels leaf cutting and chewing insects like:
Leaf cutting bees on your roses and lilacs
Asparagus beetles
Tomato hornworms
And a couple Hawaiian species of aphids but be careful.

To make marigold calendula spray use Calendula officinalis commonly known as calendula, pot marigold, and English marigold.

** remember this is a spray only***

1 cup marigold flowers and leaves crushed and mulched
1 pint non chlorinated water
Strainer or cheese cloth

1. Mash 1 cup (225 ml) of marigold leaves and flowers
2. Mix with 1 pint (500 ml) of water
3. Let soak for 24-48 hours
4. Strain through cheesecloth
5. Dilute further with 1 1/2 quarts (1.5 liter) of water then add 1/4 teaspoon (5 ml) of liquid castille soap or SM90 as emulsifier **
6. Spray target areas** Castille soap is made exclusively from vegetable oil as opposed to animal fat. Castile soap is made exclusively, or predominantly, from olive, coconut, almond, hemp, or jojoba oils. Castille soap is commonly found in organic health food stores and online.**SM90 can help lubricate soil and hydroponic systems, but mostly as a follicular emulsifying wetting agent for transferring nutrients and EM or IMO to plant cellular structure. Works unbelievably in auto-misting or fog nutrient regimens.
