Testing The Quality Of Your Coco Coir

Many people that I’ve came across in person and online doesn’t know how to test if their Coco Coir needs to be cleaned or not.

When washing large batches of Coco Coir, it can be a pain in the butt for us lazy people, so with this method, you can test a small batch of your coir using things you already have at home

Things you need…
PPM Meter
Measuring Cup
RO Water (I use tap in a pinch)
Large Bowl
Strainer.
Coco Coir (Duh!)
Clean spoon or Hand.

Take 8 cups of H20 and pour it into the large bowl, then take note of the PPM using your meter.

Take 6 cups of the Coco Coir and mix into H20 with a spoon or your hand, then let the Coco/H20 mixture sit for 20 minutes.

After 20 mins, take your strainer and place it over the measuring cup, then pour the Coco/H20 mixture into the strainer.

When enough of the liquid is collected back into the measuring cup, take your PPM meter and test the liquid.

If your meter is reading over 200ppm, you will need to wash your coco.

I use just tap water, and my tap water is 70ppm, and when I tested this new batch of coco coir I received, it was 125 ppm, so no washing was needed.

You can use this method also if you’re recycling coco coir at the end of the grow.
