ok im switching to coco coir?

I am making a lot of mistakes am I supposed to water like soil or not and am I supposed to have a double bucket to prevent it from draining to quickly or is it supposed to drain out like soil ? I was switching to coco coir but trying to keep it as simple as possible so this is the 2 ways I am confused yes it is droopy I know that's the issue it's either too much water or not enough it goes from droopy to crunchy ? So drain like soil or double bucket or

The whole point of coco, is that it dries quickly. You don't want to have a bucket under your container. Maybe a catch pan. Let her dry out before you water. Maybe get that light, a little further away. What are you watering w/? PH? PPM? How often?
