............Annnnnnnd relax

Seems quite a popular thread

Anyway, back to how these boards have preformed so far

26 days of 12 hours on , 12 hours off.
I have moved all plants to the "Fattening" room this evening.
I have also moved the Growgreen lights into the "Fattening room".

So the plants are now under the following setup.

Area - 5 ft 6 inches long x 3 ft wide x 5ft tall
2 x Growgreen boards are now running at 150 watts each
1 x Quantum Board running at 150 watts
5 x Cree cxb 3590 running at 200w.
The lights are around 16" from the canopy.
3 plants along the back wall and 1 in front middle.

Lights in action

These 4 plants were in a 32" x 32" tent under 2 x growgreen boards running at 100 watts each up until this evening .

Thank you, one and all for looking in!
:cool:

sorry to see your light board lost some of it's luster. Glad to see your GrowGreen board is still shining bright. thanks for the update.

Nice looking grow. I see the Strawberry is finicky feeder. Looking great glad to see your fattening room fattening up with more light
peace

What revolution? You mean what Robin and Stephen started and you stole their research and found the supplier to undercut them on their hard work and research to show the samsung diode kicks ass.

You've handled your entire project like a grade A Douche. I mean you actually did design a good product but act like a real tool when it comes to any form of criticism or questions.

I was surprised to see you resurface here after the BS you write and not explain but instead call us bullies. And for someone who writes namaste a lot you have a ton of built up negative energy, maybe you should try smoking pot to relax and not get all bent out of shape when someone asks you to explain something.

Peace.

I will say it again, selecting diode placement according to manufacturers specs is not a trade dress, aka original.

Nextlight "beat" them to market by a year or more anyways.....so I wish people would at least know the history of the bandwagon they choose to use......

Yeah but he got dogpiled by a bunch of bullies.

Why any vendor would get into a fight with another on this site is a mystery to me. Very selective crowd, wide range of backgrounds and generally a tough sell here. They would be better off focusing resources on high traffic sites with less sophisticated customers.

Plus as a vendor you are totally exposed and a sitting duck for someone who wants to cause your business problems. Import is still under federal jurisdiction and complaints from concerned citizens are taken seriously by the port authorities.

I corrected him about the double slit experiment a few months ago and he reacted EXACTLY the same way. I simply said his description (of the experiment) was not really accurate and he friggin' had a cow. Wrote in all caps "YOU ARE WRONG!", then a few messages later he accused ME of saying that to him and put me on ignore.

The guy has serious issues. He has an inability to simply admit when he does not know something, instead he'll pull stuff out of a hat (like the right hand rule) to try to sound like he knows what he is talking about, when he clearly doesn't.

I have no problem with the product he has made. It seems to be just fine, on par with other similar LM561C based products. I DO, however, have a problem with his outlandish claims of said product.

And I just had exactly the same kind of interaction with him in the last couple of days.

He's extremely thin skinned and starts screaming about lies and then in my case moved on to threats in an email exchange we had.

There are plenty of reputable vendors here. He can't be bothered to get a retailer tag and then freaks out with no provocation.

Find someone else to sell you lighting.

I have been in discussion with my supplier, Jeff Wei. He told ,m last night, there is going to be a slowdown in production of the LM561C 3000k and 3500k diodes towards the future as Samsung rolls out the LM301B 5000k diode with it's 33% cost increase.

Jeff informed me he is going on vacation shortly, two weeks, 30Sept - 15 Oct, and upon his return 3000k and possible 3500k LM561C will be in short supply or not available. I can only order 3000k before 30 Sept. After that date questionable at best for 3000k

I have a few boards with the 5000k/3000k mix spectrum left. The future boards will be channel 1- 5000k Channel 2-2700k until further notice.

I have been having dialog with my rep at my manufacturing facility in Shenzhen. When we talk about power, from his perspective and that of his peers, they look towards the number of diodes on the pcb. The relationship appears to be that every 96 diodes represents to them as 50w of power indicating to me approximately 0.5 watts of power per diode.

Why is this worth a discussion?

The pcb with the most active diodes will produce the most power. The pcb with the lowest amp draw will produce that power the most efficiently. The goal is to design a board that runs at low current with a high number of diodes driven at a current that is close to the maximum output of the diode approximately 150-175mA., with low heat output through design of traces adequate to dissipate heat quickly and efficiently.

The GrowGreen board meets all of these criteria and has not nor will not fail, unless you attempt to overdrive the pcb with a psu larger than what the board is designed to work with, as well as have excellent heeat dissipation based on design parameters..

The GrowGreen board on average uses three drivers, an HLG-120H-C1050A/B, HLG-185H-C1050A/B, HLG-185HC500A/B, and an HLG-240H-C1050A/B driver for max output possible. At max output the GG board draws 1.98 amps @ 225w. At average output 1.85 amps @210w.

The psu C1050 uses less amps than larger psu's and therefore costs less than larger psu's, with lower operating costing for the same area.

Detractors can say more costs less, but common sense does not agree.
