natural red clay. i think most hobby stores have it.some states have natural deposits of it.when all else fails,ask a highschool or elementary art teacher. i use a bit of clay half the size a marble,work a pinch of osmocote into the clay well,form the tablet into the desired shape and let dry. as long as you put the root tabs deep enough and securely in place there will be no problems. if they are not you will invite an algae bloom. you can make a bunch up at once and store them in an airtight container. also great for house plants. lasts about 2 months per dose.i should mention that the clay will turn into a slimy clay glob. but it will not hurt anything.just a little residual remains at the end.in a npt you would never notice.
