Which "grow" light? #891014
Asked December 26, 2024, 1:25 PM EST
I hope to improve germination of Italian red/long onion seeds. I start in trays with soil-less planting mixture and cover damp mixture with plastic or dome. Mixed results on germination and seedling growth in sunny window. If a grow light would help, what do I look for?
Thanks,

You're on the right track. Although natural light provides support for healthy vegetable seedling growth and development, "day length" can present a challenge. Thus, augmenting natural light with artificial light to extend the length of time plants are exposed to light is a great workaround.
