Our 8oz Ultimate substrate jars are the quite possibly the best on the net! We have worked for over 15 years looking for perfection! We finally found it! We have combined special organic brown rice flour with vermiculite, mineral water, Liquid worm...

So far so good. Product came as expected, on time as always. No complaints. Mycelium is doing it's thing with no issues so far. I'm still a beginner and Midwest has not let me down in making a quality product including their grain jars and bulk substrate

This is my second time ordering from them. Every time the order shows up within two days. Perfectly packaged. Every jar has started to show signs of growth. I think this is a great company and I highly recommend. I did have two jars from my last order become contaminated but I think it was improper sterile practices. Midwest grow kits is great and I’ll continue purchasing jars from them. I’m glad I found them! 10 out of 10 recommend.

100 percent success

I was lazy and chose to inoculate all 6 of my jars using the open air technique after spraying disinfectant around my space 5 minutes before tackling the jars; I also, flamed my needle with a butane lighter and cleaned it with the alcohol swabs as I went from jar to jar to get off any vermiculite. I still had a success rate of 100 percent. All 6 jars are now full of mycellium with no signs of mold or contamination anywhere in them. I am so happy with this product that I suggest it to anyone interested in mycology. I had tried another vendor before but, with them my success rate was very low. Thank you midwestgrowkits.

100% great so far
