T12 Wavelengths / Lumens
I do not have T8 fixtures so let's forget that issue right now. I have grown lots of seedlings under fluorescents for years now.
What I'm curious about is whether one believes a Sylvania Cool White Plus bulb (4100k rated at 3,000 lumens) is better or worse than a Sylvania Sunlight bulb (5000k at 2,250 lumens). I put 4 bulbs over each shelf. Are the extra 3,000 lumens more crucial than the wavelength difference?
The difference in cost is $25 for a box of 10 5000k bulbs vs. $13 for a box of 10 4100k cool white plus bulbs.
I don't grow trying to get fruit indoors. I'm big into peppers, tomatoes and tons of other veggies.
I'm just wondering which would produce nicer seedlings if used. I look forward to replies/thoughts.
