Leave it to a few Colorado college guys to make something this great. I was given a sample of this and tried it out. My plants jumped in growth so I ordered some. I have since made it a given when adding nutes and the girls are loving it. I now believe that this helped the plants live through the mistakes I made in the beginning and now that everything is dialed in they are out of control. I pushing this to all the people I like.

Great juice! It works as advertised and I see healthier and happier root systems! Thanks

Hydro shop suggested it's use because I grow organically and naturally. Buds are much tighter with more resin production. Seems to work with outdoor soil better. Indoor showed increases also. Not sure how it will work if using chemical nutes. I've recommended it to my grow buddies.

Only been using it for about 2 weeks, but I think its working. YHS will hook you up. Very helpful folks. They took care of me!
Received product lightning fast. Price was the best I could find. Will definitely purchase here again!
Mammoth p is a great addition to your garden but an even better addition is QUICK BLOOM LIGHTS they really are the most reliable company I've found, continuously offering the highest quality products, fairest price, quickest delivery in the game. Much love.
Ive been using Mammoth for about a year now and honestly Im not sure what the hype is about? I havent noticed any difference in yield at all. Not to mention some of the bacteria they use is pretty questionable on a health standpoint. That being said Im definitely going to try a product called Urb naturals theres more results and over all healthier plant and theyre a better company to deal with.
Everything was Perfect. Packaging was awesome and the delivery was with me the Next Morning
Mammoth p is the truth if you know what your doing. It works different on some strains. They dont tell you that, but results may very depending on which strain you grow. It wont hurt your plants in any way.
Only one month from factory very Fresh Top Notch! All plants using higher phosphate and potassium will benefit Greatly from this product.
