I went and bought 2 small heaters for the greenhouses. They run on oil. They say it's going to rain the rest of the week. The heaters raises the temperature 10 degrees F. I don't know if the tomatoes will start to grow now, but at least it will keep them alive until we get some sunshine! I have a large tent like tomatoes house coming in the mail. I got it on eBay. I'll cover my other tomatoes with this tent, and put one heater in there too. You can not control all the elements, you have to trust God to feed you! It would be really hard to grow all your own food. One day I hope I can do that. I want to become self sustaining. It will not happen all at once. This is a long term goal.
