DIY Custom LED light build

Gingerbeard I wish i could help , but I don't know,lol
I've used leds,hps, cmh, this is my first grow with them quantum boards, but so far, I'm kinda impressed with it, very little heat with it, very bright too.
 
Strips actual length is 22” I’m not sure if Cutter has 1’ strips, but there are strips from. Bridgelux and Samsung available in 1’ size. They’re cheap as beans to buy and could be used as side lights.
 
I can’t really speculate about QBs since I’ve never seen one. But there is a wide range of Kelvin color LED strips. Use 5000k or higher led strips for small veg tent, then 2800k or 3000k strips for flower. For extra flowering kick, simply add a few extra emitters for far-red to help fatten the buds.
 
Here’s a few upskirt shots to show the light coming down through the plants. I did a moderate defoliation last week because the girls were very dense. Humidity was becoming an issue.

YYCannabis congratulations on your completed install...! Are your drivers constant current or constant voltage and are they mounted remotely outside of the tent? You are going to be quite happy I’m sure.

On my photoboost I’ve used a 15ft power cable to the drivers and a 10ft dc feed to the strips. I have some blue boosters and Emerson red strips I am going to add optionally to see if that makes a difference. Still only running with the 100k pots around 50-55%. Using a non-contact thermometer the heat sinks hit 77F and the drivers about 96-100F. Overall inside tent temps are about 75F. Comparatively, the 315CMH temps run 68F inside but it’s a smaller 40” square tent 7’ tall. I’m hoping you have a chance to take some temperature measurements. My exhaust fan is the Cloudline t6 in both tents but obviously one is 60% smaller so the t6 is powered down a lot slower.

once again, congratulations...I can see the difference in your photos
 
Farmall Im running 4 x ELG-150-48B drivers mounted outside the tent. (See pics). I’m seeing temps of approx 90-97F on the drivers. I’ll have to get temps on the strip heatsinks.

What are you using for the Emerson effect to turn the red lights on before the main lights? How much sooner do the reds turn on?

Cheers
YYC

YYCannabis every light I’ve had usually came with a timer of some sort plus the ones with the pull out red and green tabs I’ve used all my life. During ANY period I have HAD to depend on them, they would some how screw up. As we both know, that can be a problem of monumental consequences in this activity. I bought a few TP-Link units and in the last 3 -4 yrs, they have performed flawlessly....once I saw the ones with the dual plugs and now even a power strip I’m hooked. On the duals, each plug has their own programmable scheduling. The phone app or iPad is simple to use and the schedule function makes it effortless. I’ll never go back to a mechanical timer again. In running over 40 strips, they all go on/off at the exact same time and I’m using 4 duals to control them.. and I really mean exact same time.

You don’t need Alexa, just wifi
 
YYCannabis Thanks man. This is my first time using quantum boards, seems to me like they got great penetration.
But I'd still like to get 4 strips ,for the lower branches, even though I probably don't need them, in that small tent, but I'm getting them anyway.
Thanks again.
HappyGrowing.
 
Easy to setup and you won’t be disappointed.... again, congratulations...I’m too old to be so excited over this kid of crap but, I just can’t help it 🤓
 
The Emerson effect is only used to extend the daylight hours with out stressing the plant into hermi. This is done by leaving the red, at a very specific wavelength, on for the first hour after the other other spectrums have been shut off.
 
Toker1 that is my original plan. Problem is trying to retro fit in the same 2x4’ frames that contain a well filled array. Then, accommodating their power needs and timer using a completely separate led driver component. Biggest problem is getting the free time to screw with it.... on the other hand, nice to have fire suppression if I mess up :)
