Excellent inoculant

Teraganix EM1 is an excellent inoculant. I use it when cooking super soil, during every transplant, pre-bloom, and I’ll add it to a few compost teas during flowering. I highly recommend EM1.

Probably the best microbial in a bottle.

The product showed how full of life it is from the first application. Not sure if its normal to get a bottle that will expire in 4 months but like I said, this stuff is alive

Great stuff

Works great. Very alive. I have since made a bunch more from using just that one bottle I bought. I put it in my rez to get rid of that "basement funk" smell I was getting, put it in teas, and even used it to make a spray to get rid of pet odor. Works great for many applications in your garden and all around the home. It probably should be a staple product in everyone's home.
