Coco is amazing. We all know peat is not sustainable and we shouldn't really use it. Just make sure you buy quality coco,from a company that buffered it to a neutral ph. Coco usually comes from india and companies buy it in bulk 5kg block and just put a label on it to sell to the public. I tried using it once as is and saw how bad it was,this was when i just started getting to coco.
So now i wash it out after it expands to rinse away all the salts to basically make it a "lifeless" medium. You have to add everything into coco coir because there is nothing in it but salt. You get different grades like fine/course. It definitely needs a lot of perlite to fluff it out and not compact for your roots,and then it needs all the nutrients to go in. Do i think it replaces peat? yes 100%. Its the perfect thing fto add in container growing and seedlings,but like i said you still need to add to it to create a mix to your liking,coco is just the base.
