Salt Lemon boy was a real work horse for me here in the hot Southwest.
The way I look at it, it is better to have one home grown tomato in the salsa than two from the store.
Anything and I mean anything beats that stuff.

Plus they are almost work free.
No way can I afford the earth boxes and no way can I stay home and water containers with drain holes all day.
So far I have not had any problems with water.
