I’ve been using Mother Earth Coco Peat for a few years now, and I absolutely love it. I reuse it grow after grow. I just add in about 20 to 25% new soil after every other grow to keep it fresh.
I’m currently doing a run with 6 autos in Earth Dust organic nutrients, and 5 autos getting my normal Advanced Nutrients feedings. Here’s a link to my journal if you want to check it out.
