DIY with Quantum Boards

Also worth noting, every digital timer I've had has failed in less than 2 years. All my timers are mechanical now, never seem to have a problem with them, the oldest is 5 years old.
My oldest mechanicals are about 8 years old Brinks, covered dial plug ins. Only trouble has been occasional operator error. Visual and tactile and seemingly bulletproof.

You've walked in and only one panel was lit. It would help to know if it the panel lights up at all during lights on then turns off at some point, or if it just doesn't light up at all.
Just doesnt light up at all. Ive gone down always within 2 hours of lights on.

Light still isnt firing up. Ill pick up a new mechanical just to rule out the timer.

Its weird cause if unplug and plug back in they both fire up. This digital is probably around 4 years old

If you take the light in question (driver and boards) and just plug it into an outlet, does it light up just fine?

I have a theory the BSpec with it's 470nm will increase carotenoids/orange pigment. Does anyone have any results of this. Any evidence that pistils are orange due to carotenoids?

We had some issues one winter with a 135w kit not lighting up in cold weather. It would flicker on and off slowly until it warmed up. The light on time was in the morning and the temp was about 48-58F in the morning.

Yeah this doesnt flicker. It just doesnt start. If I unplug and plug back into it fires up.

Here's some more experiments I've done on plant pigments, specifically with anthocyanin. I've really dialed in my grow environment to produce purpling with a basic setup. The lights are 4000k qb120s or qb132s. You can see on the peppers where the are green, they were covered by leaves. The 4000k is producing more pigment than the 3000k I had in the past due to more midrange green-orange spectrum.

And as far as I know these pepper genetics don't have any background of purple color which was a surprise proof of concept. Typically they grow green-orange-red as most peppers do.

Stem/branches turn purple on my plants where exposed to 4000k Old CMH Light, lesser effect noted from 4000k and higher LEDs. Outlines of shading leaves are even visible on the branches. I first noticed those 10 years ago.

How do you know this is due to orange-greens in the spectrum? Why not blue for example?
Purpling can also be down to High Irradiance Response, especially if its only stems.

Interesting. Do you have 3000k photos to compare this with? Have all plants been from the same seed batch? I'd like to see this done more scientifically!

This is great, man. I'm so tired of the "it's genetics" excuse.
Check this post out, check out the picture... zoom in... interesting.

Thanks for posting this.

Hey I just came across this and I don't know where to post it to share, not starting a thread. "Air Sensor CO2", at RapidLed. Looks kinda cool, maybe a bit similar to Pulse's new device (which does some other stuff too).

Anybody using/familiar with qb132's? Lemme holla'tcha:

I'm not an expert but I think You'd have to look at the spectrum charts, I think kelvin rating is just an average of the light color and doesn't specifically describe what light it contains. But I think cmh has some of that mid range orange and green.
