Of course you can get your plant sick. Why do legit grow ops make workers change clothes and suit up? Its not grasshopper prevention, so.. Whos drawing the line between one microscopic bug and the next?
Either way, Monsanto will fill your body with weaponized fusarium at some point in the future. Then its all over.
Hopefully it isn't happening already? You know the intestines and a plants root are literally the same (the mammals root is just turned inside out). So anything that applies to stomach bacteria applies to other types of soil. Your poop is your "soil" and the same deficiencies, namely lack of beneficial microbial life, will decrease your quality, plant or person.. Monsanto knows all about this. And so do probiotic growers...
