Greenhouse Growing for Beginners: What You Need to Know Before You Buy and Grow

Greenhouse Growing with Leslie on the Joe Gardener Podcast

Greenhouse growing can extend your growing season, improve seed starting, protect plants through winter, and even help you grow food year-round. But choosing and setting up a home greenhouse involves a lot more than picking a size and finding a sunny spot.

In this episode of the Joe Gardener podcast we talked about how to choose, set up, and successfully grow in a greenhouse.

We cover greenhouse size and placement, sun exposure and orientation, heating and cooling, ventilation, irrigation, grow lights, seedling heat mats, temperature and humidity, and why your climate and the plants you want to grow should determine the greenhouse you choose.

I also explain why cooling a greenhouse can be harder than heating one, why even a sunny greenhouse may need supplemental grow lights in winter, how temperature differences can cause leggy seedlings, and which greenhouse tools and sensors are actually worth buying.

Whether you're considering buying a greenhouse, setting up your first backyard greenhouse, starting seeds in a greenhouse, overwintering plants, extending the vegetable gardening season, or trying to make an existing greenhouse more productive, this conversation can help you avoid some expensive greenhouse mistakes before you make them.
