LED Red and Blue Spectrum lighting

[jon.hatcher]

hidhut.com is promoting these new LED lights that are supposed to be far superior to HPS and MH, yet they only use 90 watts. THey have red spectrum for flowering and blue spectrum for veg. Does anyone own these yet or seen them in action?

I've been reading up on these too. They are able to target more of the proper light frequency to plant growth where as a hps uses a lot of wasted light. I don't think its there yet but they are looking promising for the future.

presumably they work really good, and i cant see why not.

however, theyu are STUPIDLY expensive. for one comparable to a 400 hps, its like 3-4 times the price

hehe, that is true, WAY over priced even if they work as stated. I have yet to see anyone who's done an entire grow with just the new LED's, though I've seen them used as supplemental lighting.

Yeah that is the problem I'm seeing too. But like all new technology, they'll go down in price eventually.

It would cut power costs too.

thers a point where the savings will match the overpricing, but thats probly about 2-3 years into the bulb's life or more

you can get them off ebay for a not bad price from htg <- prity good company, but i saw some pictures of people growing with them and they looked prity scrawney wasent too impressed but i hear there supposto be amazing

hmm, if i actual bought that, could i start to finish grow some plants using only these lights led?

They work fine for vegging. The problem is, nobody has come out with an LED system for budding that can come close to the results HPS will give you. And of course, LED arrays are damn expensive, but this will change in the near future.

Actually, the red led is better than an HPS. The red spectrum it puts out is more easily used by cannabis plants during the 12/12 flowering cycle. There is also a blue LED that is the right spectrum for vegg.

I am aware.

However, show me a plant budded solely with LED, and less than $500 worth, one that doesn't look like a scrawny piece o crap, and I'll show you my 5th nipple.

People are concentrating on one color for veg and one for bud. Some companies mix in one or two other colors, but I don't think anyone has figured out the correct combination yet. It is going to take more than one certain nanometer for veg and one for bud, to see something really good happen.

So we'll want something that's mostly 420 nm (easy number to remember) for vegging and mostly 669 for budding. I don't know, maybe 70% each with about 5 or 10 other colors making up the remainder. It's going to take some experimentation to figure out the best combination, which nobody that I know of has taken the time to do. Veg LEDs are no problem. How we are going to build something for under $1000, that is solely LED for budding, and rivals the yield of a 1000 watt HPS (or even a 400W), is beyond me. I don't see it happening just yet, but I believe it will come within a couple-three years.
