These guys make the best true bio-complete compost I've ever seen. It's pure magic. Seriously. I've never seen so many beneficial organisms at once than when I scope this stuff out. If you're looking for a complete collection of aerobic microbes, look no further. Catalyst has you covered with the entire soil food web. These folks are also some of the rare few who really know how to cultivate beneficial fungi in their compost. You will see incredible results no matter what you're growing. I guarantee you won't be disappointed. Believe me when I say it's worth every penny!!

Their compost was delivered and it looks and smells amazing!

I liked to see all the education that they put out on YouTube and Instagram. We’ll be using the compost in our fabric pots outdoor this season.

Keisha, the creator is this compost changed my life for the better and helped me though soil science school. She represents the best of what humanity has to offer this world and her compost is equally representative of the highest quality available. She gets my full support.

I am super stoked about the quality of their compost. It was full of microbial life and they tested it with a microscope before it went out. This is what we need to heal our soils. They really set an example for other compost producers.
I've also got one of their t-shirts "mircobefarmer" that I love. It's super comfy (soft) and I have gotten a bunch of compliments from random people about it.

Real compost. Had mushrooms growing when I opened the bag! You can tell how rich in organic acids (fulvic and humic) and microbial life this compost is by how well it stays in solution with your compost extracts. The team over there is a bunch of stand up individuals as well. Get you some compost, you won't regret it!

Catalyst has amazing compost that I use to make extract and tea for my permaculture landscapes. The compost is full of beneficial microbes. This company is run by incredible, intelligent, and knowledgeable people who want to help the Earth.

This stuff is magic. Catalyst checks their compost to make sure it is biocomplete with all the helpful beneficial microbes and fungi. If you’re gonna get compost, make sure you’re getting the full microbial community along with it. You’ll find that in Catalyst Bioamendments’ compost.
