How to maximize your Mammoth P application

Historically I have discouraged people from using specific microbial inoculants when growing, as many of these microorganisms can be found in greater concentrations and diversity in a properly made aerated compost tea (ACT). In fact, many of the "instant compost tea" or "microbes in a bottle" products I've looked at under the microscope over the past 10 years tend to be dead or completely dormant. 

When I met Colin, the founder of Mammoth P, at Cannacon I was initially quite skeptical. However, he was able to answer all of my questions to my satisfaction and got me interested in the possibility of adding specific p-solubilizing bacteria as a way of increasing plant growth and health. I saw some independent positive trials on the product, but saw cost as a big obstacle still. That got me curious....is there a way I could replicate some of these microorganisms as a way of making the product got a bit further per application?

See the video below for a further explanation of my experiment: 

 

In my experiment, I setup 3 different tests with the compost tea brewer:

1. Mammoth P + distilled water

2. Mammoth P + distilled water + unsulfured blackstrap molasses

3. Mammoth P + distilled water + organic alfalfa meal

4. Mammoth P + distilled water + KIS Organic Microbe Catalyst (what we use as a food source in our compost tea brews)

In conclusion, it appears promising that you could increase the biology in Mammoth P by adding a food source and brewing it similar to an aerated compost tea over a period of 24 hours. This experiment bears repeating by others with microscopes, but I'm hopeful that some growers will also attempt plant trials in this fashion as a way of incorporating Mammoth P into their gardening regimen where it may have been unaffordable before.

NOTE: It's important to keep in mind that I did not test to confirm that the particular species of bacteria that Growcentia claims on their product label were increased. Instead, I just looked at the product out of the bottle with no other microbial inputs and attempted to determine if the morphology (shape) of the microorganisms were consistent across all samples as the biomass increased over time and with an added food source.

I have added some unsulfured blackstrap molasses starting 2nd week of flower. Will this help? How much should I be adding per gal. of water? Thank you. Or should I be using the Microbe Catalyst (Azos?)

I would be interested in seeing how the Mammoth P reacts to The Nectar For The Gods Aphrodites Extraction. Have you tried that?

Thank you for doing this experiment.
After brewing the tea, what would you recommend as the application rate? Do you think it remains the same as the bottle? Or should it be increased?

I would suggest starting with 2 oz. per 5 gal. brew, using either our Microbe Catalyst or organic alfalfa meal as the food source.

How much Mammoth P are you adding to a 5 gallon brew (4 gallons of RO water)?

Thank you

Tim, you’re good! They claim 4 species on the label apparently (it’s not listed on my sample bottle). Thanks for taking the time to watch the video. I’m hopeful that growers who wish to use microbial products like this, can do so more affordably by brewing them similar to how we would an aerated compost tea.

It kind of looked like the greatest diversity was from the bottle. Are there 3 species? 4 maybe? Definitely the greatest volume with molasses like you said with a lot of non-motile types. It is difficult to tell without PCR or some other refined testing method. I’ve read about and sometimes (think) I’ve seen bacteria which are motile transform into non-motile with a different appearance (morphology).
