    Bridgelux EB Gen 2 Thermals

    Yeah I did that same thing my first grow with this light, and the previous grows as well, but this time I went full 100% from the first 12/12 day on. These things draw so little power, what's an extra 10 cents a day over trying to get just the right amount of light (which probably isn't enough)...

    Bridgelux EB Gen 2 Thermals

    Holy smokes you had all of that going in one 2x3 space? That's incredible and I can see how you had to move a couple plants out seeing as just one plant in my tent already feels like it is packed. Have you posted a picture of your light anywhere? I'd love to see it and a friend of mine has been...

    Bridgelux EB Gen 2 Thermals

    Haha yeah it is a mess in there. Everything below the lowest elastic grid is pretty thinned out but the canopy is pretty dense. I always think I should defoliate the top so I get bigger buds lower down, but my yields are high enough to meet my needs and have plenty to give away to friends so I'm...

    Bridgelux EB Gen 2 Thermals

    Yup I am still running this exact setup with the only change being that I've had to replace the dimmer potentiometer since the original was bad from the start. I've never had any condensation on the light panel, with an ambient (out of the tent) humidity of ~55%, I have a controller inside that...

    Bridgelux EB Gen 2 Thermals

    Yeah agreed, that's way more light than you need. I run 9x at 205W at the wall in my 2.5'x2.5' grow space (32"x32" tent) and it is plenty to get 10oz from a single plant per grow. Running at 1.3A per strip you're going to need good heatsinking, at the very least aluminum u-channel for each...

    It's fairly straightforward, the way I did it is to wire them all up in series and use a switch to effectively disable certain strips: Imagine each strip is represented by one of the LEDs and the power supply is on the left. All you need is a SPST switch with one terminal connected before the...

    Bridgelux Gen2 BXEB-L0560Z-30E2000-C-B3 First Look

    @Randomblame did a great job of covering all the different ways to dim the drivers, but since you asked about a digital pot it sounds like you may have some electronics building experience. The "DIM+" output is actually a 100uA (IIRC) current source so if you're looking to digitally control it...

    Yeah I am at 8 1/2 weeks into the flowering. The bud in that photo might be a little undermature but it was the photo that was in the best focus, it is hard to get focus with a 10x closeup filter on the lens. The others are showing brown trichomes on the leaves and those on the bud starting to...

    And in conclusion, I find that the light does in fact grow plants. I apologize for not being able to get a better photo of it (single Sweet Amnesia plant) but the plant is collapsing under its own weight and since I'm cutting it down today I don't feel like stringing it all up just to take a...

    A single terminal connector doesn't have a max voltage rating, because there's no reference to measure the voltage against.The most potential that can ever possibly really exist across the two connectors is defined by the EB2 board design's isolating and tracking distances and not the...

    It was a veg until it seemed to fill up all the space with light stress training then a flip to 12/12. It takes what it takes! It is actually the second grow in that space with the same Ebb and Flow system, nutrients, a 7gal fabric pot with the top 20% cut off, and fans. The last grow was 2x...

    The power strip I am using has 4x 5V USB power ports on it, so I just used some "microusb boost" modules to step up the voltage to what I wanted the fans to run at. There's no RPM feedback or control, just a dumb voltage source. I originally had one with an Arduino Nano driving the 25KHz PWM...

    Oh man real nice work there @wietefras with the IR sensor for plant temperature. I put my FLIR in there to make some thermal image timelapses but unfortunately, the FLIR firmware will charge the device's battery over the USB connection (to which it appears as a standard webcam and mass storage...

    Bridgelux EB Gen 2 Thermals

    They're rated to run at design current (700mA) with no heatsinking but at 1.4A you'll be pushing 72C in a 19C room. In a grow room where it could be 30C that's bumping the max and would probably drastically reduce the life of the LEDs. I would not recommend it but it might be right on the edge...

    Thanks @Randomblame! You're right, the numbers do not seem to match up at all with that chart. If I check using this chart generator with a 0C difference between leaves and air I get 15.2 which is exactly what I calculated there. But if I manually subtract 2C from the air temp and use the 0C...

    Eeee they're kind of in the sameish ballpark. The Samsung F564B series (2x rows of LEDs 560mm) 3000K strips are about $29 for 8670 lumens (168/W at 1120mA) and the EB Gen 2 are $7.50 for 2390 lumens (175/W at 700mA). So for the same lumen output you'd need 3.63 of the EB strips which would be...

    Yeah I've seen a bunch of people strap one of the Growmau5 Far Red Intitiator Pucks on their build. I wanted to try it but $29 and I'd need another timer/relay to turn it on and off? Forget about it! I laid out my own version with integrated esp8266 to drive it (just using the Sonoff-Tasmota...

    You can see full details of the thermals of this build in an older thread I created before I had all the bells and whistles Bridgelux EB Gen 2 Thermals. My old 2x Vero 29s were only being run at 1050mA as well but I never saw more than 170W at the wall for them. It would run completely passive...

    Or - If the LED light fixture still works, it just doesn't have enough features yet. I replaced my 2x Vero29 light in my 30"x30" tent with a new Bridgelux EB Series Gen2 build and took the time to implement some new features. On its face I have 9x 560mm strips (5x 3000k, 4x 5000k) run by a...

    ***SONOFF - WiFi Wireless Smart Switch***

    I am just finishing up my first grow and used a big cardboard box with a peltier mini dehumidifier in it as a test. I also put a trash bag over the whole thing to try to keep the stink in. The dehumidifier was connected to a wifi outlet running Sonoff-Tasmota and turned on and off from my...
