  • Take your grow to the next level.
This stuff is like magic! A little bit goes a long way and the results are outstanding. I wouldn’t run without the beneficial bacteria and this blend is perfect for flowering. The bottle makes it super easy to measure out and administer without a bunch of waste.

  • Doing a test run will edit results
Pricey product compared to what I usually use but after alot of research. I found that the microbes use in mammoth p are different from other microbes on the market. Since I use a phosphorus based nutrients I figured I'd give it a whirl I will edit after 8 weeks or so ✌️🍀 Edit: love this product will not grow without now. I use less nutrients and get bigger yields. Super happy. ... show more

  • Growers Must Have
I have already reviewed the smaller 250ml Mammoth P, so this larger amount just proves how awesome it works for me. I use for seedlings to flower to finish! Great stuff, amazing research backing. I encourage you buy this product, then educate yourself on it with the videos and literature online about how mammoth p works. It is truly amazing. Follow directions on bottle precisely and you will find this stuff stretches a long way. A must have for any feeding system or nutrient line. Organic or the right way.....synthetic. ... show more
