The Chinese Quantum Board Knock Off Builds

[charsi420]

If you feel your giving about 4 hours too much light then yeah back them off a bit (rather than dimming, you got temps on point) and try to bring them closer slowly and up the nutes a little as you bring them closer. If you drop the light 6 inches in one go you will have probs, defs abd bleaching.

Thanks. I'd cut Cal-mag to half (2.5) after seeing some minor clawing on a couple of leaves. PPM dropped by over a 100. Using CFC feed chart (late veg).

Will be switching to the transition feed this week. Should I keep it at 2.5 or go back to 4-5 ml?

Not too sure what to say, but maybe getting some Epsom salt for foliar would be a good idea. Cutting Calmag in order to remove nitrogen (for the clawing) seems counterintuitive. what medium do you use and what PH?

edit: this isnt really my strongest side, you should see if anyone else wants to chip in and maybe some pics if you get some observable symptoms.

Some say if you raise ph a little, just over 6, mag will be more available. again, listen to everyone, not just me.

Thank you. I'll start by restoring Cal-mag to what the feed chart suggests.

if you dont have any signs of defs maybe just wait and see with the light a bit higher seems like the easiest way.

 

[charsi420]

Yup, no signs of any deficiency...

Just got 2 600 watt bars today.
Anyone interested let me know what info or pics you would like to see.

So these only draw 450 watts. Not completely ripped off but I do feel like they kind of got me. These were ecospeed lights.

Quick pic of them on

The kit has arrived! Took a minute to ship out, was waiting on stock, but holy DHL! Left China Sat AM and was at my door Monday!


Something sketchy about the stickers on their drivers. Why paste "LED DRIVER" over the MW logo? Cheap adhesive, too. I started peeling one of the S/N stickers off as well. Can anyone validate authenticity?


I dont know LED diodes very well but they sent a promise of authenticity lol its not signed


Heres the diodes




Instructions say wire in paralell. Anyone got photos of a 3 board parallel build with neat tidy wiring? Struggling trying to figure it out.

Of course the SN is stuck on or they would have to change a program to print every label.

Jerry Kingbrite has been a reliable supplier before of cobs that tested the same as originals. Id simply forget about the whole question of diodes, theres really very little that can be done to either prove or disprove. If they were fake or not top bin they would be close enough.

Driver: i allways advice you buy it somewhere more local. 7 years of wareanty that becomes useless as youd have to send it to china for warranty.

Connections: 2 x 4way wagos; + on all boards and driver to one, - on all boards and driver to the other. I recomend shrink wrapping it later to gain some water proof. Also ground the heatsink, this can be done using the driver.

Thx RS. Wasn't questioning the diodes at all, and thought it odd that such a "reputable" company would cover up logos on the drivers. I did my homework on Kingbrite before I bought -however- i didn't find you guys until afterwards.

And yeah, I'm no newb to electricity, there's only one way to connect in parallel...just looking on ideas for wire management. Was thinking about picking up some of the zip ties that have the screw hole, if I can find them. I just want things to look tidy.

Good point. And though it's a better quality sticker than the one that said "led driver". I expected an embossed plate or something similar.

...just looking on ideas for wire management.

such as which connection to use on which boards and how to lay them out for the least "wire everywhere" look.

There are more than one way to do parallel, but a wago "junction" connection is preferable to daisychaining: daisychaing is going driver + to first board +, second + on first board to second board +, second + on second board to third board + etc. This is not adviceable as you may see some voltage drop and lower light on the last board in the chain, also means that first board connectors recieve full current and will run hotter than desirable. For low current, 2 boards daisychaining with ability to adjust voltage using A type driver its its of an issue.

Hmmm

Well ill put them together and if they make bright light im happy

Touchè

 

[its.always.420]

Neat n tidy, er, something like that.
Drivers may end up remote anyhow.


Shes bright as F, im happy.

When I made up a light w/2x 288's, I daisy chained, and only the first lit up.

Someone helped me troubleshoot that, and also said that all the wires coming out of the powered wagos to the lights needed to be exactly the same length.

It's easy with 2x boards.

If that is important, Its.always.420 might want to take it into consideration.
