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...

My friends and I have been buying these jars for almost 5 years, Ive tried to duplicate them on my own and just dont have the results like I get from these. I dont know what your ratios of ingredients are but they are spot on. Please dont change anything!! Also, thanks for shipping so fast! I think everytime I order I get my Jars before I even get a tracking number!

Not sure why I have trouble with the 5lb bags.. but the ground up grain in these jars is like nitro… 100% successful inoculation every time.
