EM-5 Now Available through BuildASoil.com with Free Shipping

BAS Plant Wash is a versatile tool in your garden and is typically home made. We realized that most gardeners needed. BAS Plant Wash and it was already too late for them to start brewing it all up and fermenting it. After we realized this we set out to create a product that would only include the very best ingredients and be shelf stable. Below we provide the recipe to make your own for free but have found that most people prefer to purchase our Pre-Made and Shelf stable BAS Plant Wash instead.

Ingredients in our BAS Plant Wash:

Purified Water, Organic EM-1, Organic Apple Juice Concentrate, Organic Grape Alcohol, Organic Yucca Extract, Organic Apple Cider Vinegar,  Organic Peppermint Essential Oil. This is safe to spray on flowers when diluted and is best used throughout the growing season. 

As always, we are giving you the recipe to make your own spectacular homemade plant wash. The fermentation extracts properties out of plant materials and the alcohol and retains them in the liquid. The EM•1® in the recipe is the fermentation catalyst.  This is an all-natural concoction that can be made by anyone and is not harmful to humans or animals. It combines water, EM•1®, a distilled spirit, molasses, and vinegar. The most successful programs with BAS Plant Wash involve alternating its applications with Activated EM•1® and EMFPE. The essential oils that are the active ingredient in the BAS Plant Wash are exempt from EPA registration as a minimum risk pesticide.

The formula for one gallon of EM5 is as follows (1:1:1:1:20): 

  1. 3/4 C EM•1®
  2. 3/4 C Molasses
  3. 3/4 C Vinegar (white or apple cider)
  4. 3/4 C distilled alcohol (vodka, whiskey, tequila)
  5. Add some other plant material (fresh hot peppers or garlic...or fresh herbs that have known pesticide properties like mint leaves, lavender, eucalyptus, mella luca, neem, etc.)
  6. Fill the gallon container with warm water (110-120ºF)
  7. Seal and ferment until pH goes below 4.0

Spray EM5 alternately with EM•1® or EM•1® Fermented Plant Extract through a hose-end sprayer.

Often people will set up an informal program as follows (Diluting the AEM•1®, EM5, or EM FPE with 500 parts water):

Week One: Apply AEM•1®, 1 gallon for 1/2 acre property
Week Two: Apply EM5, 1 gallon for 1/2 acre property
Week Three: Apply EM FPE, 1 gallon for 1/2 acre property
Week Four: Apply AEM•1®, 1 gallon for 1/2 acre property

This pattern is repeated throughout the growing season.

Use 1 ounce per gallon for normal foliar spray use in container gardens.

Use up to 8 ounces per gallon for problems such as the growth of algae, odor-causing bacteria, and mold stains.  

Use as general house hold cleaner for any purpose.

IPM game on swole

EM-5 is soaking 6 pairs of snips right now and I just wiped down two heat mats, two cut trays, and sprayed down some small fans (turned off) and a tent. Point being I clean each tent with this in between cycles and generally clean all my garden equipment with it. A much easier and greener alternative to bleach, alcohol, hydrogen peroxide, and any other harsh cleaning methods one may employ. FTW!
