Plant Parenting: Seedlings Need Grow Lighting to Flourish
October 7, 2019
Tiny Seedlings Need LOTS of Light!
If you’re growing in a space with little to no natural light, then artificial grow lighting is mandatory for plant propagation and growth. Seedlings, in particular, will almost always require grow lights - even if you have bright windows.
The time of year you propagate indoors will also influence your lighting needs. If you start your seeds or take cuttings indoors during winter months, you’ll find that the lack of light and briefer duration of light can really slow things down.
Seedlings require intense amounts of light for specific durations; most windowsills simply are not bright enough, for a long-enough duration, for healthy seedlings. Plan to leave your grow lights on for 14-18 hours, depending on the amount of natural light available.
Grow lamps will need to be placed close to your seedlings - within several inches - in order to deliver the volume of light your seedlings need to thrive.
