Assessing Light Adequacy for Lance-Leaf Sundew

Red Tentacles and Dew Indicate Good Light

A grower provided a photo of a lance-leaf sundew under 12-hour fluorescent lighting, asking if it’s sufficient.

Plant Shows Healthy Coloration

The plant displays red tentacles and abundant dew—clear signs of adequate light. The enclosure is unnecessary; this species thrives on a sunny south windowsill without a terrarium. Our upcoming DVD Grow Carnivorous Plants Volume 2 debunks the humidity myth and covers tropical sundews and Mexican butterworts (release: mid to late November).

Happy growing!
