liquid cooled led`s ?

With the new larger style of led chips available

50w 100w 300w I have seen 500w and a working 1000w chip that works but the company making them can`t cool them effectively yet.

I thought well we have liquid cooled cpu`s so why not leds ?

My idea was to have a cooling radiator that is placed outside the grow area with a cooling fan and a pump system to circulate cooling gel

Doubt I`ll ever build the system but it seams like a good way to cool a very large led ?

Hey Konassure, I think it would be a great way to cool the array!

"No matter what 400 watts is going to pump out some heat, so we designed this system that separates the heat from the environment, even for 400 watt lights"- said some HID rep years ago after getting cool tubes in stock.

Why can't we look at it like this, keeping the leds as cold as possible increases efficiency, but venting heat into your room, when you could otherwise extract it with no interruption to environmental controls, just doesn't makes sense. I like the idea of liquid cooling, especially because it would probably use less wattage, and it would definitely produce less noise. The industry is biased against liquid cooling and proper ventilation, because they feel that point was matched when leds first arrived, when in reality it's a point of expectation that is constantly expanding. We should always be trying to lower wattage, increase growth, and cool down the diodes to room temperature, but the bigger picture should be viewed and that picture is "What is my total grow room efficiency?"

Any and every led company rep on RIU should ask themselves this. I'm sure that this topic was discussed, but I think that this thread could be of great use to the community. As an average grower, who buys their systems, we can't make alterations to improve performance, because we simply don't have the resources. All in all though, if a company was able to make absolute ghosts of lights, I'm sure that anyone and everyone would want a piece.

If anyone out there has a tent and led lights, you should stop by with dimensions, and how quickly the room heats up when totally sealed. Everyone on RIU would ultimately benefit, and we might just come up with some good ideas on temperature controls. That is if the OP doesn't mind?

I have a 3'x6' room, ambient temperature is 70'F at 40% humidity when I walk into the room each night, and upon sealing the room temperatures climb an average of 10'F every 15 to 20 minutes, by that time humidity is up to 55%. Essentially I can seal the room for little 20 minute periods, but I need to be in it in order for enough CO2 to be released to be beneficial for like 10 minutes of enhanced growth. I have a biomass CO2 generator in the room that has a 83'F ambient temp and produces a fair amount of CO2, but not having a sealed room is killing any benefit the CO2 has. This winter I'm ordering an A/C with dehumidifier so that I can have; cooling in the flowering room, heat in my house, and distilled water to experiment with.

Sorry if I'm making a mess of the thread, you just got me thinking about a million things and I thought I would share.

Well

I have an idea but would need investment




There`s a 1000w led for you forget about spectrums for a min they could be custom made add a liquid cooling system to that and say good by to hps forever !

Ok so my tent Jeeze things change up in there so much

Last grow 2 x 300w led panels 1 x 180w led and oh around 400w of cfl god maybe 600w of cfl

Half the supply from an 8000 btu air con vented into the room and 6" extractor fan running all the time.

1 fan in the room for circulation and a 4" in fan on the lower deck to supply fresh air.

All in a 1.2m by .80m tent that`s 1.8m high, yes I am crazy ! the light is blinding but instead of stretching the plants grow bud on the roots ! lol just messing

With no aircon it heats up to 36 to 38c

With the aircon set to 21 to 22c in the room the tent is in but not in the tent I get temps from 26c up to 29c and humidity is at 60% today but I can drop it to 40% if I need to.

Umm I don't know if you have seen most of the grow panels out there but they generally have like 1000w made of 5w LEDs. These LEDs being 5w don't produce enough heat to actually need water cooling. I mean if you had a LED producing that amount of heat by itself so 1x1000w LED diode, the amount of money you spend on that as of today would make a water cooling system pocket change.

Hypothetically though if you did need a system like that make sure you have a waterproof LED bulb then Buy a cool tube (air ventillated tube for cooling light), Buy a computer water cooling sysem. Lastly buy some platic tubing to match the cool tube size so 6' or 8'. Then set it up like a computers water cooling set up but instead of using the copper plater that is used to cool a computers CPU, run it through the cool tube and you're done although that set up would cost you $600+ just for the cooling.

I was thinking like one of them liquid cpu coolers from that old liquid cooled pc that pc world had on sale for £300 a few years ago just find a broken one somewhere

5W led`s suck this is the problem 3w 2w and 1w anf 5w`s are find if you want to be effcient but if you want to power into the plant and get real concentrated light then big chips is the way to go, 50w led chips with 90" reflectors for up to 1m plants maybe 2m

The 1000w led was going to replace the 1000w hps as the heat will still be less but the light will be more you can grow in the same way as with hps just on a smaller or larger scale and get more light for your power so get nicer bud.

It could be a good system but I`d only ever need 100w chips anything over that would be over kill but with a few 1000w led`s and 30" lens`s I could light my whole garden in winter during the day to give me the light and heat of summer, maybe for as little as 2000w to 4000w my whole garden say over 1000 plants

Just need to move to a place where I can do such a thing and I would

a old liquid cooled pc for this single beast of 1000W... lol, they are good for 100-200W

here we go:
140mm x 450mm/ 1000W

and don´t forget the pump & radiator

all in all
...........a nice idea!

Yeah just need someone to pony up the cash so I can get some guy in China called Chan I`m guessing to build a prototype lol

Oh wait I can just bolt the led to a large heatsink and then attach that to a large metal hood that is hooked up to the heat exchanger from a freezer or a fridge right ?

Might use 300w or so but it will cool a 1000w led easy and I can stick the hot bit outside the tent with a fan on it might be a tad noisy but anyone running one of these or over would have what 20 plants per light maybe 40 plants ? so I`m guessing the fridge pump will be quieter then the extraction would be on hps ?

wow no one has stolen this idea and built a light and tried to sell it to me yet

Well give it a year I`m sure we`ll see a 1000w led grow light using just one chip pretty soon I`m not sure they`ll be cool and water cool it mind.

Some of those on the LED chip, plus a heat sink on top of the Peltier's, "cool tube" sealed around the over sized heat sink, Panasonic Whisper Ceiling fan circulating the cool tube.

Imo, all of this is not really needed. Plants don't need that much light. Okay, so raise the light and just increase coverage. Okay, but why? Idk, I'd rather have a thousand 1W LED's and literally line the walls of my grow tents.

Also, and please don't take offense to this, but you say 1W LED's suck and yet a huge majority of LED chips are comprised of a bunch of 1W dies...

Edit-
Oh yea!

Check it.

when I say 1w led`s suck I don`t mean that they are not the most efficient leds

Because well they are

The problem with 1w leds is penetration they simply can not penetrate very far at all you need to blanket the whole of the canopy with them and you need to grow pretty short plants to take full advantage of 1w leds

A 600w hps on the other had has tons of penetration as such you can grow a 2m plant under a 600w hps and even the lower buds will fill out nice

So I wanted to find something that will kick the ass of the oh so loved hps light and that happens around the 40 to 100w mark with led`s but if we push to 100w then you can grow a whole bunch of huge plants under a 1000w led with some kind of lens on it I would guess that you could set it around 3 or even 4 meters high and still have tons of light even at ground level

A 1000w led would kick the ass out of a 1000w hps and still produce less heat, it`s a single unit and it should last over 3 years

What I`m saying is that yes 1w leds are great for someone who wants to grow tons of small plants but if you want to grow a few big plants or loads of big plants then you have to go for a much bigger chip size.

Hmm nice light I brought something a bit like that myself but mine use 4 x 100w led chips that are driven at around 75w I have 2 of them running a 5:1 red/blue and then I have a 200w 3000k induction light.

I`m just vegging some plants under 1 led and the induction at the moment and they are growing so so fast I can`t wait to get to the point where I flip them over to 12/12 and smack on the 2nd led light there ganna make some super dank crystal buds I know because my last grow got my new leds for the last 5 to 6 days of the grow and they went crazy and crystallized up like nothing I`d seen before.

I've got what may be a stupid question but with such high wattages wouldn't you just bleach out the fan leaves with these high focused intensities?

Generally, you'd have to keep the LED chips further away to prevent bleaching. Color temperature would also play a role most likely. A lot of these chips have a viewing angle of 120 degrees so the light should spread out pretty past.

Yeah the whole idea is that you can treat it like a 1000w hps well infact more like a 2000w or 4000w hps

Also it with selective breeding and hyro/aero set ups in time we`ll be able to evolve some new strains that will grow better under the extra light I`d love that for a strain to come with a warning saying "high power led only sorry hps growers " lol

WOW that got my head spinning. Imagining strains that were developed for certain spectrum, higher intensity LED lamps that would increase yields and quality. To be able to say that this strain is perfectly suited for this LED panel combination would be a dream come true! Is there anyone doing experiments on that or is it wishful thinking?

I know that Jack normally does very well under led I`ve seen someone grow a nice JH under all red leds

I`ve also noticed that one of my cotton candy`s really exploded when I turned on the leds a few weeks ago to speed up vegging

Oh well there`s an auto that is made for led`s mostly it`s Think Different by Dutch passion but any plant that loves extra light could be made to do well under led I think the key is to treat it keep your temps low and light levels high, I`m running at 22c max at the moment and around 12c min giving loads of AC`d air that`s loaded with air and have the bubblers in the hydro running at full power.

Getting some really fast growth can`t wait to turn on the last light

I`ll be running 2 x 300w led 1x 200w induction and maybe 1 to 2 x 105w 2700k cfl`s all that in an area that is 1.2m x .80m and the hight is around 1 meter going to get some serious crystal should be able to finish between 4 and 10 fat bushy plants last batch had the most crystal I`ve seen bar my mates Haze that he grew but that took 14weeks to flower and 4 weeks to veg my last grow was 65 days for some plants and 70 days for others from seed and they were auto`s

So yeah I`m expecting my next batch`s to glow in the dark lol

anything with hunger loves leds NL does very well as do most of the Blue strains as they grow ok at cooler temps Just stared a Cheese no1
curious to see how that does
They also seem to love hydro set ups
I guess its like anything.... all parts must be equal to do well
mediums, nutrients, ect need to be played around with to get the best out of them
Ive spent the last couple of years messing with autos and have been happy with the results under Leds most have been over a gram a watt grows and apart from a Cream Caramel grow that took 14 weeks from seed most were finished within 10-11 weeks

I think that once you push the light levels to 2000 par or more you need hydro or a huge root zone so the plant can make the most of the light but also you need a cold air supply as cold air is more thicker right ? So has more co2 and more o2 also keep your res tank low to up o2 levels and try to add more co2 to the green parts it gets very tricky to push plants harder but I`m sure it can be done.

I have a few LED panels of varying wattage, going up to 750 watts, and none of them get very hot, even when multiple lights are closed up in smallish spaces. I feel like a fluid system would make for some heavy, bulky panels, too. One of the things I like about my lights is that they are self contained units that you just hang up, plug in, and flip on. Good to go.

I believe THE KONASSURE is referring to single LED chips being 50, 100, 300 1000 watts etc and cooling them not 1-3-5 watt diodes making up a panel.

Ah, I didn't get that. Seems to me like having one enormous diode would seriously limit spectral capabilities. Plants use a lot more different wavelengths than just red and blue to grow and produce all those wonderful compounds.
