Gardeners, do you build greenhouses?

My sims usually have both a greenhouse and an outdoor garden, unless there is a lifestyle reason why I don't do that (like my sim who lives in an underground bunker). Growing up in Alaska, my family had both a garden and a greenhouse (all the plants like tomatoes, cucumbers, squash and bell peppers had to be in the greenhouse because the summers never got warm enough for them, but lettuce, carrots, cabbages etc could be outdoors) so having both a garden and greenhouse just seemed completely normal to me and I never even gave it a moment's thought.

In the most of my sim households, I grow several of each in-season plant in the outdoor garden, and at the end of their growing season, I keep only the highest quality individual of each type of plant and move those to the greenhouse. I delete all the extra ones. I move the new in-season plants (that were in the greenhouse) out to the outdoor garden, and plant extras for that season. So I always have a trickle of out-of-season produce, from the singles in the greenhouse, but the majority of the harvest is from the in-season garden.
