Anyhow, there won't be any issues with using the Styrofoam cups or
having them biodegrade. The "collar" will allow you to maximize the
water while minimizing the effort (of control of weeds, rot, et al.).
The stepped system is already in place so now you should be looking to
figuring out why rot is taking place. A soil virus, maybe?

Could be any number of things. The "soil" is actually a mixture of 1/3
vermiculite, 1/3 composted cow manure and 1/3 spanghum peat moss.
