550W Led vs. 20x Green-o-Matic Autos

[mantiszn]

$809 .. so that's about what £500 - seems cheaper than that other place...

Sorry dude I forgot to answer you...from these guys.....http://hydroponicshut.com/Pro-Grow-550-Watt-LED-Grow-Light.html

I like that they are selective switch which a lot of others don't have, very well made and has a 3 year warranty with a guarantee to replace your LED with a loaner whilst they fix yours if any issues occur.

The only issue so far I see is what jdizzle brought up, if one LED goes then perhaps a whole strip is not illuminated but I don't know if that is the case, I have not asked them that but you may want to. It may be the case that they do have a bypass of sorts.

He also gave me free shipping to the UK and you may mention my name, it may help both of us as if this unit works in my experiment then I will purchase a further 3x units. PM me for more details if you like.

Yes if you consider you are getting a real 420W at the draw and then compare that to most others like the stealth then this is far cheaper and yet the same quality components.

I actually paid $889 for mine, it has gone down in price since which is good too, I think he is making many more sales now as the testamonials seem to be plenty more now. Either way i have around 4-5 weeks left with this grow so you may want to watch before commiting yourself. I know for veg alone they are awesome, I was vegging 4 mothers and a table of clones with just this unit in a 8x4. Not saying it slays a 8x4 but just that the moms doubled in size and the 64 clones got to 8 inches in their allocated 2 weeks after 10 days of rooting. People may take from that what they want, I am happy so far, my only query is can it do a 4x4 like a 600...and currently this experiment is not representative of that as it is not in the flower rooms, it's in the veg room with autos.

What is your current set up?

Oh and regarding that other place...the keyword for me was they refer to efficiency a lot which is technically true of a 1W diode but still does not address penetration issues like 2W & 3W diodes do.

At the end of the day I don't care about all the technical stuff as long as it works properly, hell a hPS shouldnt do as well as it does because of the light spectrum yet it's raw light intensity makes up for it and does well so go figure....

did you say you were going to use the LED for flowering at all this time around?

I was watching an LED grow but the guy that ways doing it got offended by some dickhead and bounced. I'm interested in seeing how they do. Honestly, all I've heard is bad things from serious commercial growers, but maybe theres been advancements since then.

The 20x autos are going to be flowered out entirely with the LED, from start to finish they will been under the full spectrum, I will of course use on the red spectrum for the last week or so perhaps 2 depending on how they look at that point. Because my flower rooms are full and have been under the HPS already I saw no point in switching the lights as it would essentially be a corrupted experiment, hence this one now. I chose green-o-matic autos as they are representative of the size plant I usually flower out, ie. a 8 inch clone finishing around 14-16 inches depending on strain, the pineapple chunk seems more stretchy in nature whereas the medi bud stays compacter so I feel I am getting close to what i need to replicate, only thing missing is the actual flowering space which I cannot replicate so much. Every space is different as we all know.

What do you think of the unit i showed you? And what is your set up?

I dont tell many people this but I know a guy in Portsmouth who replaced 20x 1000W HPS with 20x 600W stealthgrow LED panels and has said with all honestly the LED did not yield more, about 6.5oz less but he felt confident enough with the result to pursue growing with them and felt that he could hone in on them so that the loss is reduced, he did however say that his quality was considerably more and actually got a higher price for his harvest than under the HPS. I have walked through this room and seen for myself that they can do a great job.

All of this needs to be taken with a pinch of salt as the overlapping of light is very helpful to LED and is somewhat lacking when one uses a single panel in a small space.

I am still not sold on whether this unit will do the same job as my trusty 600 but I have spent the money now and will certainly try to get there, without a positive attitude it will not be achieved.

And in the UK less electricity consumption and zero heat signature is defenitly a bonus that cannot be ignored. All we can do is try boys!!

that dont make sense from what i know about solid state lights...but ill look into it.

there are some 3 watt diodes that use the 1 watt chips in the same bulb to achive that rating. a true 3 watt die only has 1 chip. as for over clocking a one watt diode by 3 times to get a 3 watt rating? pretty sure it wouldnt work or would burn out in a very short period of time.

and 1 watt chips are a dime a dozen so im sure every light manufacturer would just riddle their products in them...and claim even higher wattages.

I don't work in the LED industry, so everything I know is from research. I defer again to user astroastro, who I tend to believe more than anyone other user that I have read and certainly more than any manufacturer claims. If you want a lesson on LEDs and what I perceive to be "the truth", start at this post and follow discussion for the next couple of pages: https://www.rollitup.org/indoor-growing/240615-led-users-unite-373.html#post5719632

keep up the good work....

 

[mantiszn]

what i want is a definitive list of what makes makes good LED's good..

so far it seems to be (and please correct me/add anything)

chipset
diode (watt 1W 2W 3W + size 5mm 10mm)
lens angle
wavebands?
single globe circuitry (basically if a globe goes it only affects that globe - none of the others)
penetration...

Choice of components....cree vs. some Chinese shit...can't think of anything else right now except the quality of components and you have covered many of the issues.

Have you communicated with Ben at Hydrohut and asked him the questions you bring up?

Looking good! Gonna be even better when you get that other light in there!

 

[easterbunny]

im liking this led situation you guys have going on and im think about switching from cfls and i didn't know which way to go but if the yeilds are this nice under the leds minus the heat i think im sold

LOL you are confused, this is the only light I'll be using.

Thanks for stopping by, we are starting ot see the pistils now so the fun part begins now...

do you have to get both spectrums 500 watts for veg and 500 watts for flowering is the nutural panels with red and blue good or is it better to get seperate panels for veg and flowering

I can't speak for other panels but mine has selective switch so you can choose what you want to do, the veg spectrum was fantastic for my mothers and bare in mind they are 3 footers and 4 off them plus it simultaneously covered 64 clones at 8 inch. In full spectrum it is bashing out 420W and is supposed to equal 750W HPS even though they say on their website 1000W. I am dubious, a 1000W is plenty light, but hey we'll see.

im going to have to check that out i just didn't want to spend that much on a new setup but i guess ill get it back after the first go round cause i wont have to make any phone calls for a while
whats your heat like( my biggest enemy) l do you still runn an outline to control or just induction

78'-80' all day long in the tent and there are 400W of flouro in there also. It's a 8x4 space though which helps. 1x 5 inch extraction fan for smell, not really for heat. No oscilating fan in the room either. Very good for heat I find.
