RX Green Buffered Compressed Coco Coir is a soilless substrate produced from the fibrous husks of ripe coconuts. Our coco is buffered with Calcium Nitrate to ensure consistent EC makeup and to take advantage of the high CEC (cation exchange capacity) of coco coir. This “primes” the coco to allow the fertilizer to be readily available to your plants.
