I understand that greenhouses are an option, this question is more towards being able to grow plants that normally prefer colder climates without having to spend loads of money on climate control. I am in central Florida. This question isn’t specific to any particular plant, but is aimed at growing plants that you can’t grow normally or via traditional greenhouse.
Growing plants in different climate zones can be a challenge. For people in warm climates. The first thing you need to do is make a plan. And research the climate your plant grows in likes. At our greenhouse, we use an aquarium and pump ice water through a trough that allows the plants we are growing to have the correct root temperatures.
