I more than tripled my wet growth weight

I cannot speak to the effectiveness of this yet but I still wanted to write a quick review to let everyone know how tiny this package is. The package is roughly the size of your hand. There cant be more than a few tablespoons in the bag. The images make it look much larger, and its definitely not full enough to stand up like it does in the image.Ill update later regarding its effectiveness.

Well I’ve been into Mycology for a little over 2 years now. From making my own spawn jars and pasteurizing my own blend of magical substrate & even offering these products on Etsy. I thought I pretty much had the game under wrap until I came across MGP pure powder. At first, I was very skeptical because of all the scams people love to run but I gave it a shot. LISTEN… I was not let down. Thick canopies, crazy fast colonization times and big fruits 🍄 . I recommend this stuff to all my Etsy customers who ask about additives! Dr.Myc , you are the bomb ! Mush love to all you Mycologists out there …

I Had Better; Faster Results and Less Contamination Problems since using it!

Great product!! Works as advertised!!
