I really don't have any vertical space to spare with a bigger bin and I don't really know how to go about setting up a DWC. The plants are also completely bound together because of the root growth so if I did get bigger bins, they would have to use the same lid and I don't know how feasible that is. I'm hoping I can yield enough so that I can take a break from growing and maybe try a new technique. I haven't had as much luck as I thought I would with my current set up so something has to change.
