What if a single input could increase yield by up to 16%… in already optimized cultivation environments?
In this episode, we sit down with Colin Bell, PhD — the microbiologist behind Mammoth P — to break down the full story behind one of the most recognized brands in modern cultivation.
From academic research on microbial communities… to early underground trials with growers reporting massive yield gains… to scaling a company past $1M in revenue — and then watching it all collapse — this is a story about science, business, and resilience.
We cover:
The real science behind phosphorus-cycling microbes
Early cannabis trials and surprising yield + quality results
How Mammoth became a breakout brand in the industry
What went wrong internally — and why the company failed
The 2025 relaunch: leaner, stronger, and more effective
A simple yield calculator to see what even a 1–3% increase could mean for your operation
Because in today’s market… even small gains can mean massive revenue shifts.
Run your own numbers. Then decide for yourself.

Wow was wondering how a product like this could go out of business. Loved hearing the details of what went down and just ordered a gallon from the website. Excited to have this back in my arsenal esp at these prices.
I stopped buying it because it was too expensive good to know it's cheaper now
Colin is one of the most down to earth and modest people that has ever walked in our little shop. We're happy as Fk they are bringing Mammoth P back! He's put in the time and love into our industry for a very long time. Not our favorite smells, but one definetly of our favorite products.
I want this for san pedro cactus!!
Awesome 😎 ❤ thank you 😊
I really want to hear Colins opinion on "Grease" it would be good for the industry to clarify Mikes role in the company before it split. Does alpha grease actually replace mammoth p as Mike has advertised?
Love transcending the bro-science!
P loading and pgrs
Your mistake was partnering with Jews
We now know he had tricantinal in mammoth p.The secret is out
Bloom boosters work. Doesn't matter the brand when used correctly.
Crazy Dude 🤟🏻
Awesome presentation we need your help in the UK big time sooooooooo much potential. I also experiment and have a device that can improve cured potency with electrostatics 😎💚🦋
can i get that in europe?
correct me if I'm wrong but this stuff is just microbes breaking down phosphorous, basically you could get the same result(more p) instantly with a bottle of synthetic nutrient, so basically the slides with 300% increase in strawberry yields(5:55) were probably in a organic field with a lot of phosphorous to break down(under the absorbable form)… in other words it breaks down organic non absorbable phosphorous into absorbable p, so if you're doing hydroponic there's absolutely no organic matter to break down and its just money thrown down the drain.
I guess it breaks it down quicker, but what about just putting more phosphorous at once(so that you get more to break down over time), organic growing has always worked fine without this product?
Basically an ad for mammoth p and it’s misleading using this product doesn’t mean an automatic 16% yield increase
Started using the P and the IPM they are both great. Shout out to my sales rep from grower's house for giving me samples to try.

Great story. Thanks for sharing. Microbes are huge.
Welcome back Dr. Bell… shit on corporate people. You deserve to do well
Mammoth P is the best P fixing microbes in the market. On top of that now a fraction of the cost of other BS on the market.
We wait microbial product for hlvd removing in organic systems.
