Which grow lights are best depends on quite a few factors as we’ve seen in Part 1 (light quality) and Part 2 (light quantity). It also depends on what you are wanting to achieve with the setup and whether primary or supplemental lighting is necessary. Most of the material covered in this series focuses on grow lights as primary light sources and this requires a broad spectral output.

For quick reference, we’ve compiled a list of several types of lights below that provide relatively wide spectrums along with PPFD measurements, lumen ratings, and other details when available. The list is by no means exhaustive but does represent several affordable and readily available options. Along with the rest of the information covered in this series, we hope it will give you a good starting point to make more informed decisions about which grow lights will work best for your setup.

Note: All Spectral Distribution Curves provided have been adapted to fit a 300-800nm graph range for a more standardized comparison. However, remember to check the Y axis before making any close comparisons as these values can differ from one graph to the next.

That’s all folks, we hope you’ve enjoyed this series on light for carnivorous plants. We understand it’s one of the more complex topics to grasp though so feel free to leave us questions or comments if you would like clarification anywhere. We’d be glad to help. Thanks for reading and happy growing!
