    I decided to try out this soil last year after always using big name bag dirt (fox farm etc.) I was blown away! best soil i have used, incredible results … More and the customer service is probably the best i have come in contact with in a long time. If you are shopping around, looking at other brands etc. STOP SHOPPING AND BUY THIS SOIL.
    UPDATE:
    this is my third or fourth season using this soil. I have it in a 4x8 box with three "tomato" plants in it. I put in some compost, a little perlite and two bags of Roots 707 blend just to freshen it up being used for three years.
    the plants in this soil are by far the best of all of them. far and above the other pots i have "bag dirt" in. This is the best dirt by far that i've used in the last 10 years

    So far so good… I used the buds blend for my cannabis and the garden plus for the veggies and I fed some basic compost teas to keep microbes up and I top … More dressed castings and compost as always and glacial rock dust about 60 days into being transplanted into this soil
    I will use this soil for now on
