    • 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

    • 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

    • Great product! Great price! Bigger, healthier flowers! Very low application rate!
Great product! Great price! Everything they say is true, so not much to add. Healthier, bigger flowers! Very low applications rate! Don't let the price scare you. This 500ml bottle will make at least 350 gallons of solution, and more! Go for it!

    • This stuff works. Try it, you won't be ...
This stuff works. Try it, you won't be sorry. Expensive when you look at the cost. Try a bottle for the last 6 weeks of bloom and get ready to tie up stems because the flower weights exceed what the stems can carry. I just ordered this 500ml bottle because my current run (was able to source a couple 60 ml sample bottles) has far exceed what I expected. And I I still have a week or two to go. Crazy, just crazy stuff. ... show more

    • Old product
I've had great results with the product. But don't waste your money buying from Amazon. Product is 2 months from being out of date and it says right on the bottle to use with 12 months of manufactured date. For the high price, I'd expect fresher product. If Amazon really cared they would not knowing send old product. ... show more
