I'm thinking about adding uv to the new one, gotta keep the plants short.
uv chip.Uv in the form of fluorescent light or uv chip?
No not yet. I don't really have the space for a bulb and I only need a tiny bit of uv.Have you done any research on thw uv chips? Have uv chips on my light as well, but heard they are not very efficient or long lasting compared to uv lightbulb.
The uv addition definitely keeps em short and fatI'm thinking about adding uv to the new one, gotta keep the plants short.
Yeah yeah. I just jumped into the first one without really knowing what I was doing.man, you gotta work on tinning your wires better. it'll help you not have those massive globs, and prevent cold solders which is why you have those dead rows. have you considered running everything in parallel? would reduce your resistor count, and evenly distribute load across all diodes more efficiently. a little more wire, but this series parellel configuration is ugly imo.
Is there a down side to doing it how I've planned? I already have all the resistors for it and I've already set up the star boards.All positives linked, all negatives linked, calculate out the resistor size you'll need. obviously, put it on the negative leg as that's where it needs to be for the LEDs to run right.
Full disclosure: I've never built an LED board, but I'm pretty proficient in auto and computer electrical, so it just makes more sense to me to do it fully parallel.
EDIT: thinking about it more, you could even go ghetto and chain the resistors you have, though since you were running this in series initially it'll likely be entirely too much resistance for the circuit.
not really, it just changes how the amperage and voltage flows. there's an upside and a downside to each. i'm a bit tired and tipsy so don't really want to type up a whole tutorial on voltage drop and whatnot. Check out watt's law, ohm's law and voltage drop in series circuits vs parallel circuits. It's a deep world, but I think it may glean some ideas you could use to determine what route you want to go.Is there a down side to doing it how I've planned?

Hi I'm new here check out supergreenlab they are the only manufacturer made for microgrow, check out my instagram and theirs with the same username. And i let you check out their site for more surpriseHi everyone,
I'm working on a design for a tiny grow box (10"x10"x10") and it's so small that I need to make a custom QB. LED strips don't come small enough and bulbs, which is what most people use for micro grows, definitely won't fit.
My light will be just under 8"x8" using 36 lm301b 4000k diodes in 9 rows of 4 in parallel. I've calculated the PPF to be about 25 using the lumens and spectrum of the individual LEDs. This will give me an average of about 350ppfd which for a micro grow isn't too bad.
I'm waiting on the diodes at the moment which should be arriving in the next few days. I'll post updates as I'm building it.
Here is what the spectrum will be:

I had the option between this or 3000k but I figured in a micro grow, I could use more blue light to keep the plant short.
I've heard it all already. "You're not going to be able to grow anything that small"
For anyone wondering why I'm doing this, it's 100% for fun. I don't expect to get anything good out of it.

I have a 12v 8A driver that I'm using but I'm attaching a dimmer as 100w is way too much for 37 diodes. I'm going to use about 32w (12v 2.66A). I'm still learning this stuff too so I'm not the best person to ask.How many actual watts are you shooting for in the end or is there a game plan in that area ? What are you using for the drivers dimmable ballasts or just trying to see the getting it to work and figuring out the kinks first like soldering and all? Still been fun to watch. I'm trying to figure out doing a bigger light than my 640 is why I ask.. Either way cool to watch
Ahhh gotcha makes sense once you figure out the small scale I'd imagine the large becomes easier. I may have to do similar to you just to get the concept definitely can see going big too fast as a headache either way its nice to have a reference on some head aches before I start pretty endless possibilities once you get going on it. Good luck with your project for sureI have a 12v 8A driver that I'm using but I'm attaching a dimmer as 100w is way too much for 37 diodes. I'm going to use about 32w (12v 2.66A).

No way. This is much more complicated than a bigger one. With the bigger ones, all you have to do is hook up a few led strips (like I linked below) and calculate the driver from that. I made it complicated for myself, don't make the same mistake.Ahhh gotcha makes sense once you figure out the small scale I'd imagine the large becomes easier.
