Angelique-dont know about the Costco greenhouses, but no matter what kind you get, I can guarantee you that you will not be able to grow in the greenhouse during the summer. I am in zone 8, and grow in there all winter and late fall. During the summer, even with shade cloth and an air conditioner going 18 hours a day, I would have 110 or more degree temps. Where you are, you should be able to grow tomatoes, herbs and salad greens, kale, chard etc all winter and fall-in fact, you should be able to grow chard, kale, cutting lettuces, mache, etc outside all winter, and leave the greenhouse for basil, marjoram, oregano and tomatoes. So you could have at least 2 tomato seasons, possibly 3 a year. We have fresh tomatoes virtually all year long.
