Will this light do anything?

[Why Doe]

I've had this light that just sits around and was wondering if I put it in my tent if it would help or just waste electricity. Was thinking of putting it on the bottom facing up or at the lower back. I grow 3 plants in a 4ft length tent each under 450w LEDs. I would much rather have double that, but the temps would be uncontrollable. I don't have any problems growing with my current set up, just figured I might throw this light in there since it just sits around.

Another 3600 lumens of white light is all to the good! LEDs are efficient, so no "waste of electricity."

 

[Why Doe]

I mean it's pretty bright, figured I'd put it to use

Ya mon!

 

[Why Doe]

Just didn't know if plants got any use out of 3600k white led light

Pretty much the same as they get from sunlight!

 

[Why Doe]

I heard you can grow with nothing but white light, you would get extremely sticky buds, just wouldn't be very big

Um, sunlight is white light, right?

 

[Why Doe]

Isint it more yellow?

 

[Scientific]

Depends on the time of day. Mid-day daylight is 5000 to 6000-ish K.

You can grow plants at 2700K (warm white) or 6500K (cool white). Light intensity trumps light color.

Plug it in. You coud also use it for a dedicated vegging tent or do a looooong lst'd plant

Don't put it under your plants - the chloroplasts are directly under the top surfaces of the leaves.

Light intensity trumps light color.

Err... Sometimes .

In the range we were talking about, 2700K to 6500K, pretty much, I think.

 

[Why Doe]

I'll put it the top along all the other lights

Are you postulating, then, that at equal intensitites, both of those would produce the same yield amount, all other variables being as nearly identical as possible?

Nothing so precise at that. I just see a lot of folks here fretting about 2700K vs 3000K vs 6500K. All I'm saying is that any of those will work and that how many light bulbs is probably more important than their exact color.

Okay. Yes, I'd agree with that.

I was thinking that, watt for watt, a 2,100K - 2,700K HPS would tend to out-yield a ~6,500K MH. But I don't suppose those would be considered to be of the same intensity, if one gets more gross light output per watt of HPS.
