    CalMag for pre-buffered coco?

    Hey guys, I switched from rockwool to coco today and bought some pre-buffered 70% coco 30% perlite mix. It says it is pre-buffered on the package. Do I have to add calmag or is that already done. Does this mean they just flushed the medium or does it mean that they already added calmag. Thanks...

    Coco Coir - Buffering and pH question (safe tolerance)

    Hi guys and girls... I am starting off in some Coco Coir for my little ones after a horrendous time with bad quality soil which was a BIG mistake. Burned a baby to death and stunted it. Anyway... I've opted for some Coco Coir block saturated in RO water at a pH of 6.4 to get it all fluffed up...
