LED Question

[tonythc]

My stepson brought this light home from a huge papermill where he works. This light says 6500k ,100 watt,13,000 lumens and also has a built in fan with no heat at all. My question is do some of you indoor growers think this would make a good grow light. Thanks in advance

Anybody?

It would work for a small grow box for small plants or clones if you could keep it cool.

Honestly I think it would make a sub par grow light. With that output you could grow at best one plant and that's generous considering that for one it's round so about 50% of the light is lost in another direction. Maybe a reflector could get some of that light back but not too effective. Two is the output. If you need a comparison think about a basic LED grow light like the Galaxyhydro 300w light. That light if I remember correctly has 3w LEDs and covers a grow area of 2' x 1.5' at best.

It's a novel idea. I just don't want you disappointed at the result.

You need a full spectrum to have a good grow light. That has 1 color

White light is full spectrum.
I've grown with pink lights, blue/red Cob and they don't grow big buds alone, you need some white light to grow huge colas.

So shouldn't 6500k be amazing? Lol

6500k is amazing and will grow stickier stinkier buds than 3000k but they would be smaller, some people flower with mh just for this reason.

Mh?

I started out with 2- 125w cfl's at 6500k and they worked fine for veg in a 2x4 space,then chnged them for 2 at 2700k for flower. Got some nice plants so if you use this one in a small space with one or two plants and add some 2700k for flower should do OK.
