I would think that the Colt would be worth a good dollar, at that size. And your Chia Pet as you call it would be as well, it's a serious grower.
Probably even the mushroom rock, unless of course it goes with the 33.
I know you've mentioned fragging them before, but they are really looking good and have more value as-is, I would think. Unless you're going to start a grow-out. Talk to Dez, maybe he needs a parent colony.
