489 - Using a Greenhouse to its Full Potential with Leslie Halleck
Thinking about getting a greenhouse but not sure what it can actually do for your garden? A greenhouse can extend your growing season, protect plants through winter, and give seedlings a head start, but only if you understand how temperature, light, and humidity work together. In this episode, I'm talking with Leslie about greenhouse gardening for beginners, including what I've learned from using my own greenhouse for the past six years. We'll cover unheated versus heated greenhouses, supplemental grow lights, seed starting, pest prevention, and what to consider before buying a greenhouse.
