Testing New LED Lights vs 1000w HPS

HydroGrowLED said:
The plant isn't growing vertically anymore, except for the new hairs at the top, so the light above this plant has remained constant for the last two weeks. It is in it's final stages, thickening up very nicely with each week. As per the other plants, the lights get raised every few days depending on where they are at in bloom. Once they stop vertically, the light stops moving. I tend to keep the light within 6" at this stage.

That's better...LOL...is there a reason for keeping it further away at other times? I know you mentioned bleaching at the begining of flowering but after a week the lights are as close as 3" and I didn't notice any problem...buds are starting to form so he didn't want to start moving the light right away or should he?
 
I keep the lights higher to initiate a stretch, although it doesn't look like those plants need to stretch much more... If they aren't bleaching at 3", then it's no big deal. I usually see the bleaching happen between weeks 3-4 when the lights are closer than 6". Before or after that, I haven't really noticed it much.
 
I'm liking the improvements I'm seeing in LED technology. I just wish they weren't so cost prohibitive for me right now. I only have three small spaces that I can use right now (3x3, 6x8, and 9x12) so heat is ALWAYS a factor.

I'm watching your grow closely.
 
This is going to be great! We shall learn a great deal from this thread, and the others alike.

Keep it up! Subscribed!

That's certainly one of my intents...welcome....so some say you can't see IR LED's but it's a matter of how you look at it...LOL
They're the ones that appear yellow with a blue ring around them in each cluster.
 
Y'know the Wii sensor bar thing? I believe it uses IR as a signal thingy. lol.

So take a picture, or even look at it through a camera and you can see it. I'm not real techy but the camera can obviously see what we cannot.

Thanks for showing us! It's funny I can think of a company who simply badmouths IR, and the use therein for their units. I have faith in that unit; yet only time shall tell eh!?

I appreciate your welcome. I also appreciate the time you have invested into the tests, posts, etc.

Thanks for everything,

-Go Green- !
 
A wiser person then I told me this example is possible but only feasible if LED’s work as claimed:
2 x 600 w cooled HID w/electronic ballast cost approx $1800 + $400 for veg and clone lights (400w mh for moms and some floru’s for clones)
On 4 x 8 table continuous grow over a year is 5 bud cycles (5x 10wks)
All together having to run average of approx 1500w/hr over 24hrs(lights,pump, exhaust,heating,cooling,keep in mind this is 4 season climate)
Anyways the cost works out to approx. $1600/yr for the entire cycle (veg+bud) for what 17p’s (3 ½p x 5bud cycles).
Bulbs $100+ must replace every year.


Now if you have to use the same amount of watt in LED’s to produce the same 17p’s there is hardly any savings not to mention the doubled cost of the 2000w of LED’s $4000- $1400+ (2 x 7yrs) for HID replacement costs.

If they worked as claimed then you’re talking $2000 for 504w of LED lights + $500 for LED light + fluro’s ( LED panel for moms + fluro’s veg and cloning)
But you would only be using approx 425w/hr for a cost of $550/ year.
And no bulb replacement for hopefully 7yrs but you know how that goes…LOL
Costs would increase slightly in the winter.

If you were really an environmentalist or just a security conscious individual ;-) and decided to turn some of your crop into another renewable resource like some solar panels to get completely off the grid, then to run 425w/hr is approx. 2p’s in cost.

GTe .7

Sure you can always give up a few more p’s to do it with HID’s and all but then again someone is going to wonder why you have 25 solar panels outside your shed…LOL

Awesome thread, I can't wait for the end results. The pictures look distorted up close, try using the macro option on the camera, it's usually a flower symbol. :)

Thanks I'll ask :ganjamon: to check that out...not much to update other then you really can't tell the difference between the LED abd HID plants...

Sorry meant HPS...I'm the butthead...LOL

Sry but i see some people are thinking no write as it is! :smokin2:
So i want to explain how it is...
HPS=HID
Because HID are not only one kind of lighting bulbs, its family High Intense Discharge lamps.
(HPS=High Pressure Sodium)
MH are also HID!
And btw now HID name changed to GD [Gas-discharge] Lamp.
...I got to go sleep and got no time to write it by my hand, and i'm smoked gooood, so so so i'll put here some more info about that from wiki.

Gas-discharge/High intense discharge lamps are a family of artificial light sources that generate light by sending an electrical discharge through an ionized gas, i.e. a plasma. The character of the gas discharge critically depends on the frequency or modulation of the current: see the entry on a frequency classification of plasmas. Typically, such lamps use a noble gas (argon, neon, krypton and xenon) or a mixture of these gases. Most lamps are filled with additional materials, like mercury, sodium, and/or metal halides. In operation the gas is ionized, and free electrons, accelerated by the electrical field in the tube, collide with gas and metal atoms. Some electrons circling around the gas and metal atoms are excited by these collisions, bringing them to a higher energy state. When the electron falls back to its original state, it emits a photon, resulting in visible light or ultraviolet radiation. Ultraviolet radiation is converted to visible light by a fluorescent coating on the inside of the lamp's glass surface for some lamp types. The fluorescent lamp is perhaps the best known gas-discharge lamp.

If you still need to read more or smth ... go to google and write "HID Lamp".
And click first wiki link which you will get.

-Question why i cant just add link, i just dont remember good rules can i put this type of link or no ... ^^

Hope it helps you understand wtf is hps,mh etc. have fu*kin nice evening!:D

Yes, this kind of link is ok to post - thanks for asking.

It's allowed because it's for reference, and they don't have forums at Wiki
