I'll try and explain this as best I can, it might be a dumb question but here goes....
Say for instance I have 8 7000k LEDs with 3 reds and 3 blues. If the dedicated red/blues aren't in the correct range (nm?) for the plant to utilise - can this have an adverse effect on chlorophyll production (A/B?). Something tells me I answered my own stupid question there but I'd rather be told than ponder.
Or, if you drive chlorophyll A+B production evenly with equal blues to reds (assuming they are in the right usable spectrum), or unevenly - more reds to blue, or more blue to reds. Can that be bad and stop a plant growing?
I've seen some experiments on youtube with salad under LEDs. Control 1 had white leds at 6 or 7 thousand K, second salad had a mix of whites with blue/red (equal), and the third had only blues/red.
The first salad was tall and average, the second was a little shorter but much bushier, and the third was very stout and compact. Almost deformed looking. Can anyone explain why this is? I know red/blue light has an effect on the height of the plant but I don't understand why.
Cheers
