Is this economically viable? Surely rice is one of those things that is so cheap that you are better off buying it in the supermarket.
I was just thinking that. Here in Miami, a 5 pound bag of rice can be had for $3 or $4 so I'm not sure that growing your own is worth the effort.
To me, herbs have the best payoff because you can start using them as soon as you have some leaves on your plant.
