Optimizing Plant Growth with Indoor Lighting [webinar]

Wed, 01/27/2021
6:00pm - 7:00pm

When we think about providing additional light to our plants, we often think about different types of light, growlights, LED’s, fluorescents, but there are actually four different principal characteristics of light that can affect how plants grow. In this webinar from UNH Extension and UMaine Cooperative Extension, you will learn about light and how plants use it, and how you can use artificial light to help grow seedlings and other plants indoors. 

"One of the primary functions of a plant is converting light, water and carbon dioxide into its food and structure" illuminates Jonathan Ebba, UNH Extension's landscape and greenhouse field specialist in Strafford County. "In nature, that light comes from the sun, but in our houses and offices sunlight may or may not be sufficient, depending on the plant. Not only do the intensity and amount of light matter to plants, but the number of hours of light and the type of light they experience can have a profound effect on plant development as well," Ebba adds.

Jonathan Ebba will present this webinar on optimizing plant growth with indoor lighting. UNH Extension's Emma Erler will moderate.

Registration is required and a $5 donation is optional. Register on the event webpage to attend live or receive a link to the recording. This session is the first in a six-part winter gardening webinar series to be offered every other Wednesday through March for Granite State and Pine State gardeners.
