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
