Tomatoville® Gardening Forums - View Single Post - Best Light Spectrum for growing seedlings

Michael · March 14, 2012

I have sold lighting for 40 years, but only into gardening for 10 years (I am pretty serious about my gardening). I like to use fluorescent, using 4-lamp 2 x 4 troffers with no lens, alternating between 850k and 830k lamps. These are pendant mounted with chain, 2" above plants, once germinated. This has worked very well for me in the past several years. LED is pretty expensive, and depending on which lamp you use, can be concentrated, with much lower light output. While I may not have as much experience as some of you, I have a lot of information available to me.
