Heat Mats and Grow Lights - Ep. 185

Just Grow Something | The "Why" Behind the "How" of Gardening

20-02-2024 • 20 mins

This month we’re talking a lot about seed starting and we can’t talk about starting seeds without talking about heat and light. Seeds sprout more quickly and efficiently when they’ve got the correct soil temperatures and the easiest way to do this is with a seedling heat mat. It’s not a requirement, though, so we’ll also talk about some ways you can up the ante on the soil temperatures during seed starting without a heat mat.

Once those seeds do sprout and you're nurturing those little seedlings the correct light can make all the difference, and usually even the sunniest window in your house just isn’t going to cut it. That means we need do a little investing in some lights to help our seedlings along. Today on Just Grow Something we'll explore soil heating options and various types of grow lights, including the most economical and even tabletop solutions. Let’s dig in!


*Question of the Month: “What is your most successful crop and why?” This could be a specific variety of something that outproduces all the others, the plant that you love the most, or the crop that grows fantastically well for you without fail every single year. Whatever you consider your most successful crop in whatever way you consider it successful. Send me an email, post it in the Facebook group or send me a DM on Facebook, Instagram, or TikTok… you have until February 29th to get me your answer!
