I never stated that pic was a true sine wave or a pure sine wave its a dc waveform pictured what are we arguing i never stated there isnt pure sine waves just wanted to prove that dc waveforms do exist

my statement was there is no DC sine wave. The only waveform in that graph considered a sinewave is the ac waveform. You can call it what you want, but a sinewave on a graph or oscilloscope needs to have a curve above and below zero. This curve is created by the rise and fall of current and the reversal of polarity. D.C. never changes polarity, there for, the curve is not considered a sinewave. And a D.C. waveform like in the graph would be produced by low end ac/dc conversion such as a rectifier and transfomer. Class one D.C. power sources produce an almost flat line. A battery produces no wave at all, just a steadily declining curve

My mate is running these for a few weeks now, connected to the AC side of the driver.
Another member from this forum is also using these in his setup connected to the AC side, @T-Time , care to share?
Sorry boss, I was under the impression you wanted to read the DC side of the driver. @Humple the meter I suggested was to read the DC side of the driver, If you want an AC suggestion just let me know and I can spec one out. or the one like dannykay posted will be sufficient.

No worries mate, thanks for the heads up in any case.

Pop i dont want to argue anymore, your 100 percent right about ac rectified to dc, and true dc sources have almost no wave, could you please give me a book or a link that gives that definition of a sine wave.

Garden peek ...

Cooler temps in the ROOM - at night are still 60° or so which gets the girls a bit chilly at lights out. The Purpling as began to fade and is not so dark since bumping the CALMAG and P feed/water. So things are more balanced. Anyways Blue Dream is at week 8 today and still trucking along , even though she is an auto she will get chopped maybe in a week and a half , depending on triches. The other flowering ( duck ) is at week 6 and has some weeks to burn.

Quantums are on point .... With such low operating temps , it doesn't bring any useable to the room so I may have to bump that up during nighttime.

The 288 rig and 304 worked beautifully together and may pick up some 120's to play with later.

NOW A TEASER ..... Been mentioning using an OCTOPOT after I clear these girls out.
I DIY my own .... For a ridiculously low cost build. My build offers mods so I can interchange mesh plates and holders to suit 1 gallon to 3 gallon pots / bags or airpots.
This the POT version using a modded plastic planter with a mesh root cage ... It is a 8 liter Food grade container ( no bpa or other shit ) to leach into Rez cavity. It also has four lockdown tabs with a o ring running around lid. There is ABSOLUTELY NOTHING WRONG with the original , But I tinker and build so it was a given to try my hand at it.

This one I can plant a clone , drop a 4" cube or solo plug without much issue. Thinking about growing out a 4" cube plant for transplant , we will see. Anyways , my next one will be an airpot version with the same interchangeable plate for multi sizes. Waiting on Amazon for those .... But this one is the TESTER. It does have a bubble stone port also.

I will post the tutorial in DIY later after I construct the other one.

Is there a drawing availible that shows the hole placements in the 288 boards? I want to drill my heatsinks ahead of time.

I have 4 QBs wiring to a HLG600H-54B.

The driver has 2 of the red/black +- volt wires.

How am I supposed to wire this?

It also has white and blue dim wires and brown black yellow RC wires

I entered some quantum board grown bud into a highly respected UK Cannabis Cup and managed to sneak in to joint 5th place this weekend (out of 22). As you can see from the strain list below it was made up of highly respected UK growers and breeders.

The Cup only releases the top 3 placements and I wasn't one of those so I asked for some feedback and I got this....

....you came joint 5th and got an 8 and and 8.5 from the judges and they both commented it was dense with a good amount of trichomes, smelt and tasted good and was a very clean smoke/vape

Nice one HLG :clap: those boards producing some :fire:

Awesome, good job!

If I am looking to do a grow from seed to harvest with one/two light spectrums, what would they be?

3000k and _____?

4000k?
5000k?
