I tried something like this with the devil's lettuce Quite a difference between the colors effect!

I seen a video with the little 12 or 18 inch led lights The red and blue did not do as good as the normal white light Both claimed to be full spectrum

Mine have red and blue led and it says full spectrum Have 2 red and blue and 2 white but actually has some red leds too but the light appears white

I’m so pleased as I’ve just bought a blue red light and wasn’t sure I’d done the right thing I’m new to hydroponics Great video thanks

wow very cool testing procedure I like that you catch things and are honest about some failures That's the true scientific method Keep going bro we need more brains like yours in our society

I recently purchased a couple of 3000 lumen LED bulbs They are giving a PAR reading in the range of 500 to 600 at desired height But they don't have any reddish or orangish tones I mean they are dazzling white with a very very faint golden tint Would that be a problem during the complete growth cycle of the plant? (The packaging says 6500K cool Day-light)

Great experiment Saved me the trouble of doing it myself

Still a great video and experiment, but wattage doesn't actually matter when it come to LEDSbrbr"With incandescent and florescent lights, watts were a good measure of the brightness of a light Not so with LED Lower wattage can produce more light" brbr"it's not really about wattage Wattage is a measurement of electricity consumption, and while it's helpful to know how much wattage your grow light uses (so you can make a more economical, energy-saving choice) it actually has nothing to do with the amount of energy your plants need to grow"brbr"The watts rating on a LED grow light tells you how much electricity it will use, and therefore the ongoing cost to run the light, but it tells you very little about how bright the light is, or how suitable the light is for growing plants"

Nice video

Never mind the red and blue A full spectrum is the way to go I have both, and the difference is about 20

Thanks for the video and honesty, looks like you gave the blue/red a head start picking a slightly larger plant to start with but I appreciate the info and the outcome I wasn't expecting that either
Comment from : David Dahl

Aye this was a good video man, keep em coming, need all the info I can get
Comment from : ErnieMoi

You might have said it in the video but what kind of lettuce plants are these?
Comment from : Brandon Dickerson

D'oh! I thought I left a comment already I believe the cat appeared twice (resorting to cat videos now? ;-) Those LED light bulbs bring back memories, I started growing with one (6500K 11-watt) growing a head of lettuce out of a coffee container Interesting experiment Blue thumbs up for you
