Lettuce or Crop to Grow in Raleigh ALL YEAR ROUND

How cold does it get? Are you planting in containers?

Kale or spinach are some of the most cold-tolerant.

In Raleigh I don't know if you could grow them all winter. I'm guessing they'd either die off at some point, or at least stop growing for a while. But late fall and early spring for sure.

You might be able to extend the season with some sort of mini-greenhouse, for example this:

Collard greens laugh at cold weather, too. They'll reach a point where they'll stop growing and just sit there, but they won't die until the temps reach the point of insanity.

Sorry if I belabor this point, but if I get a greenhouse like those shown in this link, will I be able to keep my lettuce on my backdoor patio without fear of them freezing? I really would like a system so that I can grow my own lettuce and veggies year round, and if this will work, it's probably the best. The next option is probably a "window sill" device indoors with some sort of lighting system. This greenhouse on the patio seems to be the cheapest...

Thanks

Two things:

2) Window sill: Do you have a south window that will not be blocked by any bush, shrub, overhang, etc? If not, you'll need to use supplemental light. To duplicate sunlight, you'll need about 10,000 watts worth of fixtures. Unless lettuce is terribly overpriced at your stores, you're probably better off buying it.

Hello,

This link should give you all the info you need regarding temperatures:

If I purchase a greenhouse such as that shown, will I be able to grow lettuce outside in the winter. I live in Raleigh, and here are the temperatures in the winter:

That's a discussion site. The proper thing would be for you to not expect us to read through all those messages. You should distill the information and present it here.

If it get below freezing for any length of time, you will need to find a way to heat the greenhouse.

How far away is your nearest supermarket? And, do you have an "I don't care what I spend" budget for this greenhouse project?

I suggest you read informative article about growing winter gardens at:

The article doesn't mention lettuce. At low enough temps, lettuce will not survive, while members of the cabbage family (in the article) will.

If the OP wants lettuce, he/she may have to add heat.
