At the end of a coco grow can you reuse it??

Hello agree to@SpinnerCaribbean, Canna has Calcium and Magnesium as single products without Nitrogen. So you can let soak the washed, and cleaned coco in Single calcium and Magnesium, without having fears to overfeed. Because calcium and magnesium are no fertilisers, and dont harm your plant as single product. You can give it to the plant without fears to burn her, because just the nitrogen in the most mxed products harms the plant

Of course , you just need to wash it with ph'd water to buffer it and I also advise you to water you coco with enzyme one week before you plan to re use it , it will help to break down the old roots that remains in the medium , I also heard that some grower are also soaking the coco in a cal mag solution to prepare the medium for the 1st re use 😊
