LED grow lights... input please.

[HARDDON]

Here is the skinny on these LED for growing your tomato plants gang...

You need at least 4 panels of 96 LED's (BLUE) and this works awesum for fresh cut clones.

FOr anything else, veg or flower stage, the LED setup will work but you will get very slim harvests.

LED's will be the future for almost all lighting in the future (say 3 years) but for growing tomatos and getting the most out of your efforts, stick with what is proven and tried and tested.

Right now, they will not produce big fat thick tomatos.

Thanks for the help, that clears it up.

Just a couple things though, would that be the 3 watt or 1? Or I guess it could be 96 each 10 watt LED's, or perhaps the 500mc ones. And I guess the dispersal angle for those is 60 degrees. Oh wait, I suppose they could be 360 degree LED's, but then again they could be the 6 degree ones. And I guess your thinking of 6 inches distance from the plants, but then it could be 36 inches, or 2. Was that the 460 or the 440 blue, or maybe the 412? Or were you going for some carotenoid, thus the 480?

I agree, that sounds about right.

lol......i dont know about that many man...ours are growing great...i dont think we are lacking at all in power or light amount, just spectrum.....IMO

Is it illegal to talk about growing tomatoes?...lol

I hope you aren't lacking in anything. I want to see a nice fat haul at the end of your grow. I guess we'll find out at harvest.

as do we........lol

For those wanting to pulse your LED arrays, why? Plants don't have eyes to trick.

Even better efficiency this way.

[Opie Yutts]

Well, what I got out of that is they found x amount of light does the same thing as pulses of light that add up to x amount. How is that more efficient? The whole idea of pulsing light is to trick eyes into thinking a light is on all the time when it's not. Plants don't have eyes, therefore they will not be tricked, and when the light is off the plant knows it's not getting light at that point. Less light = less yield.

I never quite understood that either. arent we trying to get the most photons possible to hit the plant. only thing i could figure is they're saying the plants could only take so much light at one time (kinda like a kid drinking a 2 liter...slowly).but I dont think thats right either. I realize solid state and all, but is turning on/off so many times going to hurt the leds?
