I need to know what size bulbs to use, do they need to be blue and red, and how far apart do u space the bulbs? I've got a design now but if u have any info feel free to say so...knowledge is priceless....
Thanks to all

Friends are playing with this now..... 2' x 2' panels.

they tell me they like this place http://www.quantumdev.com/

good luck. btdt

Hidhut has some available, and has a new LED product coming out next month.
"LED Grow lamps by HID Hut provide the highest lumen per watt ratio of any light"

research is out there that shows plant grow is more significantly affected by spectral energy ratios...hortilux makes metal halide called BLUE, the 400w has the closest output of spectral energy to daylight available on the market....hope this helps...happy gardening

Dank,

I'm running 2 of those 1000 blues now...This is the first time I've used them and I really don't see any difference in my grow. It may be something I'm doing or not doing but I have'nt changed anything but the kind of bulbs I use during veg. I've been reading what sounds like "good things" on the LEDs but they'll say anything for that $....

the one thing you need to remember is plants want to grow if you give them ANY kind of light they will try to grow... but to maximize your garden you need spend the extra $ on the products...if you get no improvment from led to the BLUE then look to other aspects of your environment...remember lighting is just a small piece of the puzzle,no matter how good it is,without the other pieces your garden is incomplete...

btw...the BLUE is the first bulb(mh)that will veg and flower i run a 1000w BLUE and 1000w super hps at the same time during flower,rotating the ladies under each one,and since no more yellow sun leaves twoard the end of the cycle,they finish as green as they start...some things are just worth the money...hpoe to have pics of the garden and finished fruit up soon...as they say proofs in the pudding!

higha!

thanks to you, i got en-"lightment" and the idea what to do with my next grow - project!!!

peace, Martin

Thanks, Dank...I feel just as u do ...give em what ever they need..I think the heat was my problem...got both in c tubes now so no problem.

Thanks to u also Ver...that's exactly what I was talking about at the start of the thread " is this true" ...u never know what might make another re-think his.

higha!

first, i hope my poor english fits to say what i want...:
i will get a bunch of led´s and want to know something about the color spectrum the cannabis plants need.
i can have a great variety of led´s so i want to make the best choice. as far as i know, the best for veg is a light somewhere about 2700K and then 6400K for flowering.
the ultimate aim is to create a light-system that provides the optimal light spectrum for the plants, whatever state of growing. imagine a led-system u can program..., no change of bulbs, just switch the "light-box" to the needed range of wavelength..., much saving in energy consumption, less heat, extremely high output par lumens, long living equipment.......

Peace, Martin

I am watching the whole LED thing if the claims are true we can reduce the #1 cost of indoor gardening bt until it is a tried and true method I will treat them like windows vista ... Hell no not yet let someone else figure out how to make it work right.

Heres one for you. They just finishes the first 8 watt 420 lumne led bulb. Its in the suns spectrum.This could be a coincidence but whats with the "420"

I bought four of those r/b panels for a total of 900 leds. Has'nt arrive yet but I'll keep u posted. Thanks Fletch..

i read a study that the collage in minniapolis did between 400w hps and led lights and sunlight. the natural light started the plants off fastest. they were growing regular house plants. the led lights plant at the end of the four page report were just a little bit nicer than the hps plants. the sun plants had the greatest volume of flowers and seed or fruit. the energy cost of the led was a little under 1/3 of the hps. www.growwithleds.com has prices and a link to the study.

we had this going here like a month ago, LEDs are still years from the point were today's HPS are.
modern high end LEDs cost about $80+ a piece, they don't look at all like the old pin-head LEDs, they need active cooling or burn in minutes still and get only 100lum/W. a modern 400W HPS fired with 240V gets about 150lum/W out. besides are modern LEDs limited to a power of max 3W per LED and for 133 to 400 modern LEDs you can buy an endless supply of high price tag HPS bulb and equipment over and over.

!!Everyone buying this LEDs trails today gets ripped off buy some greedy sales guy!!

that is at leased my point of view to this. peace

do you know who paid for this study? guess the people salling those did and in such are the results of that study - as with the pharma industry, every study they pay to THC turns out to the point that THC is super toxic, lets to hard drugs and kills faster then crack mixed with dirty crystal - do you call those to be of any value? guess you don't buy those either.

don't believe the hype guys! i would fell damn bad for you when the money is burned for that.

and i'm not sayin that LEDs are not promising but the are at least 2 years from the point to beat a 400-600W HPS in their output in lum/W. but hey, they have come a long a long way from less then 5lum/W 20-30 years ago to modern LEDs with 100lum/W+ and still moving, so maybe in a few month this could have all been changed already. but not till today.

peace

LED's will change the future of growing....No doubt about it....

there's a real cool article in high times this month about LED's, and a spectrum vs lumens debate...It's the issue with Willie Nelson on the cover.....I dont normally buy this mag but Willie was waiting for me to read about him.73 years old still smokin and looking good doing it........

I'm going to get me a HighTimes right now.. I love that guy!!!!!

alright i will give some of info i have learnd of led...while they are good supplemental to help increase your light foot print, on thier own they are very lackluster...while it is true plant new blue an red for growth an bud we still dont fully understand light specs an their effects on plants....ever seen plants grown soely with led's...they have a pale whitish aspect from not being able to creat vast amounts of chlrophyl plants normally...not only that they are very hot an need adquate ventaltion an the fact they are so expensive does nothing to help....so while one day led's might take over...today is not that day...with a side by side test compared led to hid,hid still is the tops...peace

(Which by the way, I needed a few new 400watt bulbs and ordered from them, they have great prices!! I only paid 7 dollars and change per bulb!!!!!)

DON’T JUDGE AN LED BULB BY ITS PRICE!


LED lights are not inexpensive, but any attempt to save on the up front cost of LED bulbs can possibly end up being an expensive proposition. The old adage “You get what you pay for” certainly holds true when it comes to LED lighting.

You may have heard recent reports about many of the problems that are now being seen with inexpensively manufactured LED components coming in from overseas. As far as the consumer is concerned, there are two main segments of LED lights: the semiconductors and the drivers that operate the LED. Many manufacturers are now overdriving the semiconductors in an effort to produce greater light output. Unfortunately this process often leads to premature burnout and lumen depletion.

A simple search on the internet for LED light bulbs will bring up hundreds of sites selling LEDs and an even greater number of prices for what seem to be identical products. With LEDs being a popular but pricey item, many shoppers are going for the lowest price they can find only to be disappointed when their purchase fails to perform as expected. Quality control at the manufacturing end has everything to do with customer satisfaction at the consumer end.

Most people don’t have the time to research the many manufacturers, nor the money to invest to evaluate the many LED products across the globe. At 1000Bulbs.com we’ve spent the past two years doing the due diligence and sorting the good from the bad. We are now solidifying our relationships with top LED manufacturers and present you with this small token of the products they have to offer.
