A Guide to Measuring Light for Your Indoor Plants: Best of Growing Joy Replay

Author: Maria Failla- Happy Plant Lady and Author of Growing Joy: The Plant Lover's Guide to Cultivating Happiness March 12, 2026 Duration: 37:04

Welcome back to part two of our Understanding Natural Light series. We’re bringing this conversation back as part of our Best of Growing Joy episodes because it’s one of the most helpful discussions we’ve ever had about indoor plant lighting.

This episode is a replay of my conversation with Leslie Halleck, a dear plant friend of mine and a horticulture and lighting expert. If you’re a plant parent trying to understand the light in your home, this conversation is a must-listen because the number one mistake I see plant lovers make is misunderstanding their light.

Most people think they have bright light for their plants when they actually don’t. Our eyes are not great at judging how much light indoor plants really receive, which is why so many plants struggle indoors.

So in this episode, we dive into how to measure light for indoor plants. We talk about window directions, the difference between brightness and light volume, and how to use simple tools like a light meter to understand what your plants are actually experiencing. We also break down why plants think about light in energy or calories, not just how bright a room feels to us.

And make sure you grab the free Understanding Natural Light download that goes with this series. It walks you step by step through how to measure light in your home so you can stop guessing and start choosing the right plants for your space.

 

In this episode, we learn:

  • What the most important colors of light are for growing plants
  • How to use a free app to get a better understanding of your indoor lighting environment
  • What is the difference between LUX, Footcandles and PAR
  • What micromoles are
  • What DLI (Daily Light Intergral) is
  • The results of my homework and how many “aha” moments I had about the ACTUAL light in my apartment
  • How drastic the difference in light is within only a few feet from your window
  • What area of your apartment is probably low light that you never knew about
  • Whether or not you can put plants in a bathroom with no windows
  • Whether or not you can put plants in an office with no windows
  • Citrus under lights, pests

There’s a quiet, accessible kind of wellness waiting for you on a windowsill or in a patch of soil. Growing Joy with Plants explores that very idea, moving beyond basic tips to examine how our relationship with the natural world directly nurtures our mental and emotional health. Hosted by Maria Failla, a self-proclaimed Happy Plant Lady and author of "Growing Joy: The Plant Lover's Guide to Cultivating Happiness," this podcast feels like a warm conversation with a knowledgeable friend. Maria guides you through the practicalities of keeping your houseplants alive and thriving, but the discussion always circles back to the deeper connection-how the simple acts of watering, repotting, or simply observing growth can become anchors of calm in a hectic day. Each episode digs into how gardening and engaging with nature, even in small urban spaces, offer tangible tools to manage feelings of anxiety and overwhelm. This isn't about achieving a perfect indoor jungle; it's about finding moments of peace and genuine happiness through the process of care. The underlying message throughout the podcast is a powerful and gentle reminder: tending to your plants is fundamentally an act of tending to yourself. You’ll come away with not just better plant care knowledge, but a refreshed perspective on cultivating joy in your daily routine, learning that the serenity you might seek on vacation can be rooted right in your own home.
