spazatak, as a noobie I did all the calculations first to find and purchase the drivers, but as Supra pointed out one should go thru and check the voltage,amps, and calculate the wattage of each circuit/driver. It is not needed by some, but it does let you know how all is performing ( correctly...

Not a bad idea Supra, it would make the process easier and much safer.

a tip: when using the multimeter to measure Amps, soon as you are done with the reading at least remove the positive lead from the meter. At least than you will not forget to do it and damage the meter or LED's when you got to read voltage. Now I can only hope I did not damage the driver or...

vertical or horizontal SCROG method has a huge learning curve. I spent years horizontal before I did my vertical setup. The key was the timing of when to flip into floral stage so that the rest of the vertical screen will fill in. Knowing your strain helps a lot and that is why I stayed with...

When I said I was getting some to light up, well that was with a multimeter testing continuity. Seems the first 3 LEDs in the string will not light up with the multimeter, nor are they shorted, guess I blew them open? Okay Pos, not so worried about their brightness now, stevesleds is where I...

To new at this game, but did jump in feet first. Now if one looks at the post "LED tower" and at the bottom is a pic of it all lite up. At the top is the hyper red LED's and they do not look so bright. I guess I am thinking they should be, but maybe not. Any how, later on checking amp's and...

I have each plug into a "power bank" is what I call it. It was used for computers and it has a main power switch that supplies power to 5 outlets, each of those have a power switch that has a breaker (fused) along with the main power switch. Some would say over kill, but I figured it was just...

As long as it grows you some fine bud, it can be as naked as you like it.

It took me a bit longer getting the new potentiometers, still one to come via mail, and it is not in the GrowRoom yet, but here she is all lite up.

at that price you should just buy the heat sink, the LED's, and the drivers and DIY. Putting together is not that hard, getting all the right parts can be, but here at this site is the knowledge and help to make sure you get what is need the first time and putting it together is not to hard when...

I would just like to say, "please pay attention to what is said" SupraSPL's words are solid on "power them up" and some does and dont's. Not that I thought he was full of it, but some things I thought best and on order already came in and I used them, not the answer. I found Supra's list was...

Not sure about the C conversion, but I have had temps. down as low as 35 degrees F and no plant damage, yet I have had temps up to 95 F with no damage as long as air was moving around well and I provided the needed water that they require when that hot. I have understood that LED's will last...

Not sure where you pull the intake air supply from, but I pull mine from under the home. Coolest point in the summer time and warmest area in the winter. Always fresh air for the girls. Another help for the plants in warmer temps is to keep the air moving around them. I used a log of muffin fans...

I will copy this good info for the future ref., for now I will have to use what I have gotten. Let this newbie crap wear off a bit as I get my hands dirty (so to speak). Learning so much all over again, seems to never end when growing this fabulous plant.

It is getting bright in here, I can not wait to see their production. Positivity it really does look good. Have to use my setup some before I upgrade. Figure I can use the older LED's out on the patio area for light. Okay that is how I will convince the wife so I can get the newer LED's.

Well I am glad it was the cheapo that I reshaped the tip on. Years ago we always shaped our tips, let heat up, dip into flux paste, than tint the tip and unplug iron. After all is cooled down, heat back up the iron and clean tip, and you are off soldering again.... and yes this works, and not...

I had lower end 60w that just burnt out on me, than used a cheapo 30w to finish up, but reshaped the tip and no flux to re tint the tip, but my wife unpacked more box's and found my medium priced 40w iron from years back, plus my flux paste, so now I have 30w and my 40w working for me. I will...

A bit amazed, out of the 126 LED's I had only one wire in contact with mounting base, fixed that issue and rechecked work. My house fuse box has neutral leads to terminal strip, black leads to circuit breakers, so I take it black (live) is hot. My mind is having issues with the multimeter...

now that my downloads are complete, and I study them, I would go with implementation 3, but I still see that the wiper contact of the pot being the Dim + ? #3 graph shows when pot turned total counter clockwise you are at 100% and when you rotate clockwise you decrease (dimming) led brightness...
