Coco Coir Block — 5kg Compressed
Our most versatile substrate. It is triple-washed, calcium nitrate buffered, with pH 5.5–6.5 and EC below 1.0. Each 5kg block expands to 70–75L of ready-to-use growing medium. As a result, it is the top choice for Canadian greenhouse growers, cannabis cultivators, and nurseries — and our best seller to US buyers.
