I do the same, my used coco or soil goes into my compost pile or directly into my outdoor beds most of the time if it looks like it'll be too much work to reclaim. It never goes to waste...BUT, when I expand my grow I'll def put more effort into reclaiming my coco.Results will vary depending on the mass of roots in your container. For instance, I use 9X9's (2.5 Gallon) and when I finish a longer growing variety, the coco is chuck full of roots. I find that in this specific scenario it just makes more sense to compost the used coco/roots. The time it would take and the amount I would reclaim just wouldn't justify the efforts in this case. Fortunately, you can compost your coco/roots and then use it for compost teas or soil later.
