WhiteKnight, I have been gardening for about 10 years now and have learned a lot. I now know what works in my area and what has a hard time growing. I did the large garden were I had about 400 lettuces and that year was great. Now I am growing in pots to see how much food I am able to grow this way so if I have to bring them in at night in a SHTF time I can do that. My test has shown that it can be done. Next year I will have 2X the pots so I will increase the production.
I also grow pineapple which grow on there own, have about 30 and every year they give there pineapples.
I think all of you should start small with three to four pots(large ones or the long ones) and test what grows best.
