To add to iaw's response, it's worth noting that a large amount of value flower has is in relation to it's presentation and appearance. Trimming of flower is done to both remove excess plant material as well as create a more favorable product for consumers.
Because this process of trimming is necessary for the sale of flower, any vertically integrated business that both grows and sells their own flower will inevitably create this excess of trim byproduct.
