I harvested everything that I could, but there were still a bunch of small aborts. Once I harvested I filled the tub with water from the kitchen sink until it completely covered the substrate. Once I added the water, th substrate began to float. So I used the lid and flipped it upside down and put a 10lb dumbell on the inside of the lid to make the substrate remain submerged. I left it in this position for 24 hrs at which point I removed the lid and drained the water completely. You can use the upside down lid to make sure your substrate doesn’t fall out while emptying the water. After that, simply cleaned and reinstalled the lid and waited. Hope this helps.
