Like I've said, many add 20-30% coco to soil due to the mix of water retention and natural drainage, the coir will loosen the texture of clay soil, reducing waterlogging. It will do the opposite for sandy soil: allowing it to better hold wate. These are just facts when making your own mix it is very beneficial, 40% compost 30% coco 30% perlite is very popular especially with the autos.
For the transplant yes, like Ive said before in comments I will do fhrm in small airpots to dry out, they are already looking better, thanks for the input.
