Just curious. How many open tins to usually have or try and limit yourself to. For me three is the max I like to have. Any more than that and I start getting worried I won't finish them off in time. I know can always jar my weeds before they dry out too much but I still try to limit myself to three max. Right now I have two open tins. One Escudo Navy De Lux, and one Peterson University Flake. I usually have one VaPer and one Va/? blend open.
