LED grow lights... input please.

By the way, the LED seller said it would take about $3500 to match PAR with a HID. I quote:

"Yes, they are AWESOME! However, to replace 1 1000 HPS, it takes 20 Red and
10 Blue Lights which translates to around $3500! WHEW! It is good to make
the one time investment, but not for the faint in the pocketbook."

End quote.

dependin on where u go for ur stuff, yeah it could be like that.. i say just get the bulbs and fuc the fixtures/ballasts.. waste of money, u can build that ur self and save a few..

I'm still waiting for the sulphur lamp... and actual pictures of a cannabis plant being grown with LEDs.

That's what I'd like to see...

[newactivist]

Me too, turtle420. For me it's just an academic interest as I don't grow but I definitely will if it gets legalized for medical or recreation in my state. I will have some pics from a grow operation in Europe using the sulphur lamps in about 1 1/2 months so I will post them as I get them.

As for the LED grows, until I get that movie from a grow movie using LED's my hands are tied. However, NASA knew they worked and if their claims are false it's a massively detailed scam, to the point of improbability. I think they will grow cannabis just fine. The main question I have is potency. Cannabis plants produce resin to protect their leaves from UV rays and from drying out. Without that heat stress I'm just not sure if resin production would be as high. Just like weed grown outdoors is stronger because of the sun compared to indoor weed.

Interesting question but one I would not be able to answer.

Turtle420, this is a link to the site that made a movie about growing cannabis with LED's. The producer got arrested and they will not release any copies but just the pic on the website says a lot.

well that movie would talk alot about temps.. hps and heat producting lamps made the novice grower succeed in pretty good %'s b/c of the heat they created with the lights// with the use of leds there is little to no heat discharge to keep the plants warm soo u most provide a sutible eco system for proper growth... with the root temps beening off on a led setup your pretty much screwed as in possiblity of success..u still need a able inviroment..this can be solved with like a 20 $ heating pad if your area is not the warmest....

lets get a few things strait.... for that quote...

thats a freakin rip off... i wouldnt touch that with a 30 foot pole....... and lets make it clear theres MORE then just one led system out there ( copy catts) ... deffinately soo when your comparing a product that has gone through 4 years of R and D by specialist and scienctist to come up with the most usable spectrum for plants and patent there findings to that of the guy saying that its going to take 3500$ worth of tracfic light leds (thats a crap load by the way...(over 30 little things dangling above you...).. to buy a similar set up.thats bs ( thats theres not ours) that shows how poorly it preforms or how much there ripping you off...with our systems an 8 bar aray puts out the equievent of 1000 watts hps...and that 8 bar aray the light is focused down to a 3 by 3 or 4 by 4 area..depending on distance away...( thats a whole lot of light for a small area) ....yea it cost a bit more money roughly 1500 or soo .....but the benifits out weigh the price...cool/ no noise operating, low electrical consumption ( less then 20$ a year) and 7 to 10 years of bulb life or 100,000 hours...can hsp beat that> good luck...

You just cant keep us all hanging?

I dont know if this helps but I have spoke with Phillips in the Neitherlands a few times and for balanced plant growth as different vitamins are produced and broken down at different wave lenghts, the proper spectrum consists of 5.3%red 36.3% blue, and 58.3%yellow light to get a proper average. Nanometers can be converted into Hz. I was working on a project to try and grow using acoustics a while back as Hz are the direct opposite of Nm. Say if the pure light of the visible spectrum of the rainbow starts at 375Nm and ends at 750Nm then 750Nm = 375Hz and 375Nm = 750Hz. It is all about the wavelenghts.

I know, ledgrower. There are other companies that sell LED grow systems for less. Believe me I'm not endorsing his products over anyone elses as I haven't done a cost comparison. It was the technology working that I am interested in.

I guess it doesn't matter who sells the LED's as long as they emit in the correct PAR spectrums. After that would come cost comparison and quality.
