You may like a product that I love to use in soil grows. It is called; Rainbow Mix
Check it out. It has a great blend of organic elements, which enhance any grow. Very affordable.
My Hydo guy gave me a bag of Rainbow Mix, my WW Autos and Fem. WW"s liked it very much.Used during outdoor soil grow.
Good deal. I like this inexpensive amendment for soil or soil-less grows.
Thanks @latewood Gonna check it out
