Coco Peat & Perlite Mix



This pack includes a 5kg block of coco peat and enough perlite to combine together for a ratio of 80/20 Coco peat to perlite which is the optimal ratio for Mr Stacky systems.   Coco coir is made from coconut husk and is an exceptional hydroponic growing medium with unparalleled root aeration and water absorption qualities…. The best!   The 5kg compressed blocks expand 8 times when added to water.   In this way a 30cm x 30cm x 10cm block will expand to 70 litres of volume!  The addition of Perlite helps to further aerate the medium for optimal results.

Each 5kg block makes 70 litres of hydroponic medium.

Coco coir is really the perfect hydroponic growing medium as it can hold its own weight in water and even while saturated can hold 22% air which is the best of it’s kind even beating the highly expensive rockwool (about 10% air holding capacity).  Coco is a ‘forgiving’ medium and pefect for beginners as it has plenty of buffer against over or under-watering conditions.

Coco coir is also antifungal and can suppress and protect plants from dreaded root diseases such as pythium and phytophthora.

Our coco peat 5kg blocks are high quality with very low salination content as the trees utilised are grown in fresh water and washed several times in fresh water to remove the salt content.

    Such a great product and have grown so many amazing veggies and some fruit too. Love growing carrots and tomatoes and strawberries and cucumbers as well as the most delicious beetroots. All grown from seeds, and yes the seeds really do grow you don't need many.
