90 Watt LED Grow Light!

Same reason I use a humidifier (well,a swamp cooler actually). Because without one the natural humidity is between 0-15% locally, which is spider mite heaven. Even with buckets of water and damp towels hanging around I can't get the humidity up above 30% without running a humidifier (winter) or swamp cooler (summer).

I haven't used an LED yet, but I have to admit they have me intrigued. Heat control is a major problem for me because the temperature in my house rarely drops below 85 during the summer and my grow area is usually 10-15 degrees hotter then the rest of the house. I've been looking at LED's as a way to avoid the need to move my grow into the basement for the summer and spend a bunch of money to run the swamp cooler round the clock, but everything I've seen indicates that the technology still has a way to go before it will be able to replace a 600w (or even 400w) HID in terms of growing ability, and the price is still too high compared to HID's that put out the same amount of light.

Ok so I just read in High Times about the HIDHut UFO Led light. Replaces a 400w HPS with built in cooling! They said it took a week longer to finnish but there was a marked increase in potency!

Oh and it mentioned that in China they developed a single 200w led that is 2 inches in length and emits 200,000 lumen! But it's a long way from production, 10 years most likely... :(

Just thought that it was cool and I'm high as balls... and lets face it, a purple grow room is sexy as shit.

Uh.... mj plants like High humidity when in veg.... low humidity when in flower.

So... He was probably using a humidifier in veg like many people in dry climates might. Makes sense to me.

Nice first post!:fire:

Anyone have any experience with the "50 WATTS LED GROW LIGHT PANEL" they got on ebay... sells for like $80 bucks. I heard they were pretty good. Anyone else?

from what i hear it's better to get a light that's 90 watts and up, more bang for your buck.

i have used the Hidhut ufo. the same one used in hightimes mag. it sucked major balls when it came to veggin. i really had high expectations for it after reading that report on the hightimes website, but if you look at my current grow and look at the time line on it from when i was using the ufo. you will c that my plant didn't grow for nothin. then i changed the lights out to a 96 watt aqualight and the change was immediate. i just recently put it back in my grow box to see if it would help out my 150hps for flowering. and so far it has.

I bought a few LED grow lights a few months ago.

Here is the REAL deal:

90w or 100w of LED does not replace a 400w sodium. You should calculate how much HPS or florescent you would use something in that ballpark, maybe 150w of LED = 175W HPS.

LED Panels made with traditional led's:
I purchased some of those 14w panels and they are a joke, but what do you expect for 14w. They hardly do anything and produce too little light to do anything other than supplement a HPS lamp, not replace it!

UFO & other 90w to 300w LED grow lights:
I got a 90w UFO light and put it in one of those 1.7"x1.7"x4" grow tents. Now that grew my plants! unlike the 14w panel this one seemed really bright. The light was not a 400w sodium but more like a 100w sodium. This thing about the LED's not being bright to the human eye but bright to plants, that is bull shit. The LED lights that my plants liked were the ones that looked really bright to my eye. Unfortunatly after 3 months my UFO light broke, thank god I did not buy it from some e-bay store that is no longer around to help me with the warenty. Yet I did have to scramble to get other lights in my tent. So I give a thumbs down to the UFO because they are too expencive to be unreliable, I think its that built in power supply not the LED's that went bad. The UFO had another unexpected downside, it was not silent, much louder than my ballast used to be, it needs a cooling fan! Also when my UFO broke I looked inside, the way these are made is a huge number of leds are built right on to a big heatsink, then there are power transformers and 3 cooling fans inside. It looked like the light did not hold up well in the humid environmet inside my tent.

High Power LED Panels:
I also bought some of those 50w high power LED panels for $150 each, finally a LED light that was worth the money. This did not replace my HPS, but I had my setup in a closet and cloning area above it, the cloning area got too hot to put a lot of florecents, but I had extra space. So I mounted 1 of these to the wall next to the rooted cutings that were growing slowly. They started to grow really fast! Since they produced no heat and no sound and good light I was able to transform a slow growing area next to my cloinging area in to a fast growing area. Oh and when the UFO broke I was able to put the 50w led panel on top of the tent and zip-tie 4 20w florecents to the corners and it is better than the UFO alone.

I have not tried flowering with LED's.

They are equivalent to 400 in usable plant light.
The brighness a human can see means nothing when dealing with LEDs

the key is the value of each individual LED.

those 14 watt panels use .09 watt LEDS, great for seedlings, useless for anything more then 4 inches away. no penetration
90watt UFOS have 1watt each for LED (90 leds)
you can also get smaller ones with 2watt LEDs with 45 total LEDS in it. same power, but gets a bit hotter.
also costs more to make the 2watt version.

Also cant really compare to a HID if your going to throw around lumen, as thats a measurement for the human eye "more greeny light"
Comparing to hid, u have to count only the actual light the plant will use, and not the far reds "heat loss energy is about 20% of those watts"

all in all, 90watt of pure triband light energy UFO is equal to a 400watt HPS in the amount of light that the plant can actually use
which is fine since all those extra light bands not getting used, is money spent on lumens "you can see".
which is useless for what were doing here.
