I’m on my third generation of seed-starting lights, a journey that began back in the day when shop lights with so-called cool-white and warm-white fluorescent tubes combined were all we gardeners knew. Eventually I moved up to newer, high-output fluorescents, and now maybe the switch to LEDs beckons. 

But how does a person shopping for grow lights find his or her way through the array of possibilities out there? That’s today’s topic, with horticulturist Leslie Halleck, author of the book “Gardening Under Lights” to help simplify things.

Sufficient light is maybe the biggest factor in the equation of success with seedlings and grow light technology is evolving fast. I asked Leslie to return to the show for a 101 on shopping for seed-starting lights suited to us as home gardeners.
