How does First Harvest Ministries utilize greenhouses in their gardening techniques?

The available content I have about First Harvest Ministries does not specifically explain how we utilize greenhouses or detail our gardening techniques. Because of that, I do not want to guess or give you inaccurate information.

If you like, I can share general, biblically minded ways ministries often use greenhouses for year-round food, teaching, and outreach, or you can tell me what aspect you are most interested in (food production, education, self-sufficiency, etc.).

What part of greenhouse gardening are you most wanting to learn about?
