Mid February. So time to start my indoor vegetable starters from seed. They will remain indoors for a while till temperatures warm up enough outside, which means they need plenty of light to grow while indoors.
I have tried various lighting methods over the years. From simple window placement, to different artificial lights. But this is the first year I decided to try LED lights. And not simple LED lights, but the red-blue spectrum lights. I am curious how they will work out. I bought a 5 meter strip roll, so I can chop the lights up to the lengths I need. It should be an interesting experiment.

What is special about the red-blue spectrum lights?

Good question. Simplistic answer is because Chlorophyll A and B absorb light mostly in the red and blue spectrum, while reflecting the rest which is mostly in the green spectrum. That is why plants seem green to us. But that is really a simplistic answer, as there are more complex interactions with plants and light, especially with larger plants or plants mostly grown under artificial lights. For my starters, those issues are less relevant, since these lights will not be the only source of light for my starters and once things start to warm up outside, these starters will also start to spend a lot of time outside under cover. I simply thought it might be fun to experiment with the blue-red spectrum lights to mostly see if they can help to avoid some “legginess” in some of my starters. More info with followup posts (and I have no idea if this will work or not, so we shall all see). Hope this helps.

Have you considered keeping a few starters out of the red/blue light? If you can keep the other conditions the same, you’ll get a better idea if the light makes a difference.

Wonderful reply. Very much the experimental method way of thinking. I approve.
I was considering only doing an “ad hoc” approach this year, based on my experience from prior years (including all the variables that would make my “this year” trials fully invalid experimentally). Given the limited amount of LED ribbon I ordered I can probably not do a proper experimental treatment. But your comment got me thinking. So I will see. If not this year for proper science, then maybe next year. All the best.

Led grow lights are very essential for growing plants indoor. I like it very much .
