How to avoid making a disgusting amount of white dye w/ crafters

Recently came here for help w/ a bonemeal farm and I have certainly fixed my issue but I decided to add on a crafter to make some bone blocks for space-saving purposes. I have an observer clock set up to a 4-tick repeater to avoid making white dye, I sat by it for a while and it never made any so I thought I was okay, I left, and returned to an amount of white dye I fear I will never ever get through. Is there another way of auto-crafting that can avoid this issue? I have this set up at my bamboo farm too but of course one bamboo makes nothing so I didn't realize this would mess up w/ a different recipe.
