Question, I came across a small tub of unopened General Hydroponics Rare Earth at a thrift store and snatched it up. If I used it in Daz's auto super soil recipe, would it be a good replacement of the azomite? Or the humic acid? I'm collecting ingredients and am wondering if this can be used or how to use it. I use a homemade octopot wannabe automatic SIP setup if that makes any difference. Thanks
