Mike Daly from EMNZ shows how to expand EM1 in large volumes 

Of course

one week or untill you get ph of 3,6

Our policy is to use expanded EM ideally within 30 days but up to 90 Days. Anything over that and the microbe numbers will begin to drop.

Thanks - I did understand this due to the limitation of available "food" for the microbes. But what has me confused and reason for asking, is the activated/expanded product being referred to as EM RTU. When reading on your site i see "EM Soil and Crop is a ready to use product - EM RTU?" and looks to have a shelf life of up to 6 months. If activated/expanded product = EM RTU, and Soil and Crop is referred to as EM RTU, why does the EM soil and crop last much longer? "EM 1 products e.g. Soil & Crop, Environment and Garden it is 6 months and for our EM Ready to use product it is 1 month." I may be a little confused with the way you refer to your products.

That is a good sign Syrus. That's something we would expect.

Thank you so much, Sir Mike. Thank you for sharing and answering our question. God bless you always. You're a good Samaritan.

Microorganisms are most active when at room temperature

Sir temperature 20-30?

yes you can keep making it, spray one a week on both soil and all over the plants

Yes the Indian Government is also manufacturing a similar product known as Waste Decomposer.One can search this on internet.It doesn't require the mother culture again nd again.U can expand the culture using water nd jaggery or molaisis

What was that hot water temperature ?

the same what would happen to you

Thanks for the message Jessica, 3.6 is correct and the ideal zone being 3.4-3.8.This is where the microbes in EM will happily sit in relative dormancy before they are applied.

Ahh okay thanks. I think possibly I was thinking of aerobic bacteria as I just read recently that the bacteria you are using is anaerobic hence why there is no air stone needed to make up a tea. I am running hydroponics so I think a beneficial aerobic bacteria would suit my plants due to the fact i aerate the hydro reservoirs. They are not grown in soil so I will be inoculating the system frequently. I guess this is more suitable for dirt grown plants.

Hi Jessica, The Microbes in EM are facultative which means they operate in both aerobic and anaerobic environments. I would definitely recommend EM for hydroponics we have had great success in this area.

the low ph keeps the bad micb from growing

We no need to add Air Tube into the Tank?

20-1 so for 200L you would be looking to add 10L of EM and 10L of Molasses. Once you have expanded you EM1 generally for foliar applications we recommended a 1/100 dilution (so 10 milliliters to answer your question).

Thank you for your great idea and sharing your knowledge. I am doing it right now... expanding my EM1. I will apply this to my poultry farm to minimize flies and foul odor. If this works, you have save me loads of money on vitamins and pesticides.

Hi Syrus, did this work in your poultry farm?

Yes, it work in my poultry and piggery. It lessen the foul smell and bring down the coliform of the lagoon.

For expanding EM1 the conventional ratio is 20::1 meaning 20 liters of Water for 1 liter of EM1 and Molasses (EM1 =0.5 L and Molasses =0.5L). In some areas in South East Asia, the expanding ratio is 20 L of Water for 1 L of EM1 and 1L of Molasses. Once expanded within 7 days of incubation, the dilution ratio for foliar application is 100:1 meaning 100 L of Water for 1L of EM solution ready to use.
