perfect led grow light?

[oldmac]

... I repeat, I have seen not ONE impressive plant grown SOLELY under L.E.D. sources ... when they do, I'll try to buy it ... :smokin:

hey IR,

Here's about 50+ plants that are soon to be impressive.
That's 660watts of LED, lighting abt 4'x4'.

I would love to see one

I think there has been ample evidence that led's will work. Just have to get the lumens up comparable and the price comparable to HPS. The systems I've seen are just too expensive to consider right now.
A system that would put out 100,000 lumens for about $400 would be a good price.

[headshake]

how about DIY kits that will keep the price down? at least as an option for the technically inclined?

I agree all those pics need more time, and then you will see LED's are not up to par with a good HPS.

**Some one show pics of the final week so every one can see the problem.

I recommend just trying to mimmic a HPS in lumen output, then add some UVB to the mix as well. Unless the entire ceiling is covered in LEDs I dont see the LED happening to soon. Cost for high out put LED's is expensive then you need thousands of LED's for just one grow room. when faced with a 30 dollar a month light bill for a 1000W is far more less considering the amount you gain in harvest

what would be a reasonable price? we will do our best, but just as long as quality is priority

I apologise; I am unable to find on your website any specifications for your emitters: voltage, current, wavelength, manufacturer, binning, etc.

I am also unable to find documentation of implementation of your products in horticultural applications. Specific information in that area is welcome.

How competitive with units of this type can you be?

I suggest to be stubborn and not take the RQE curve for your spectrum.
That is only based on how leafs of just a few crops react and other effects were never taken into account.
Most things we have no idea about really and only one thing is absolutely sure: no light beats the sun so far!

You can take that spectrum to start with and run controlled experiments to see if any other configuration can beat that. These experiments are very important to get specific know how and market your product.
The more tests you run the more chance you get ahead of the competition.

You have to hand your sets to the very best and most respected growers.
They can give you the best input and are opinionleaders in the market. Meanwhile you have the results published in the magazines and forums and get a strong and trusted name. Very important after so many people got ripped of.

A good (water)cooling system would be very important.
Also you'd need a timer for the far reds and a little extra moonlight.

How much for a 200W light?

[ForgetClassC]

Not to be a dick, but there is a typo on your companies website. Homepage, pole, it says, "Would you switch to LED's if they were ony a little...."


Just thought I would let you know.

someone post pics of plants at end of flowering not vegitative that does not mean shit to me ,ufo is pure junk a fire alarm with l.e.d. on it ,what about the procron or whatever its called that supposed to give 400

I have used Procyon 100s, and they work very well. Even I who have experimented with LEDs I was surprised how well they will bloom. But to think that thay are an "identical" exchange to a 400hps is just silly. I used two (2) to replace a 400watt MH in my mom room. But that alone was a 50% power savings. They will not veg a plant to 4+ ft, they lack penertration, but if you keep your mom's to a reasonable height they work fine.

BTW: I sold them as part of a aero/fog ponic grow tray set up. The Procyons will actually work from cutting to finished bud....and only raise the temperture of a 3'x3' tent enclosure abt 2-3 degrees over ambient.

In my experiments I have found that even a 600watt HPS is not adequate to cover a 4'x4' grow area effectively, it is no match to the 1000watt HPS. But in an interesting experiment I found 2- TI Pro-blooms at 330watts each will compete easily with a 1000watt HPS.
The 1kw HPS actually uses 1,150w w/ballast vs. 660w; that's 490watts savings and none of the heat provblems associated with HPS. Plus using grow trays designed for SOG style plants (138/4x4 tray) I can outproduce the 1kw HPS by a good margin.

Will you see a picture of a large 4' or more indoor plant grown indoor under LED? Probably not, it would take way too many LEDs, but why grow that big indoors? We just don't have a difference in light preference, we have a difference in grow philosiphy. I don't believe in growing large plants, with big fat stems, and lots of branches with all the associated leaf material indoors. Thats the stuff I'm going to throw away....I just want big fat buds! Small plants, many of them gives me the effeciency to use LEDs and that increases effeciency more.
