Grab an Earthbox or two and you’ll never run out of peppers. We usually put three or four plants per Earthbox and they fart out WAY more peppers than you can ever use. All it takes is a sunny or at least semisunny spot, an Earthbox and remembering to water them once a week.
And for the record, I love the flavor of Habanero and Scorpion peppers (both make great fruity sugar cookies once you remove most of the capacin by poaching them in milk), but ghost peppers are bland and not tasty at all (other than the ridiculous amount of capacin). I have a hard time believing others really like ghost pepper flavor by itself.
