That's the exact driver I stated I was going to use above..the AB version that caps the voltage and current which is why I still don't see a thermal runaway from a slight variance in voltage. I'm still interested in seeing how much one pulls over the other just for curiosity. If that driver can...

I thought the 1st post said 400W. Is it 400 or 600W? What brand, some of the 600W you get off of aliexpress might only be 300W. Anyways if it is 600W that might be a little much at full power and if you can't dim it you need to raise the light. I generally started my light at 24in (2ft) above my...

How close are the led's and are you running full power? Second, what is the temp and humidity? The soil has nutes in it already right? Leds require running the room a little hotter than hps due to them not having IR. I personally found 80-85F worked well for me. I've not used this app yet...

Seems like that can happen even if all strips are the same and one has some issue. In my scenario I'll have 16 strips at 48V and 8-10 at 46V so there's a buffer there. Everything is so dam expensive these days..Aluminum bar used to be cheap. I've never got a answer on this question in the past...

I bought some mother earth coco from Amazon and re-hydrated some of it for seedlings. I noticed on day one that it didn't smell like the coco I've used in the past but then again it's been a few years; it has a off weird smell...maybe almost like formaldehyde. Is this due to them washing it in...

Right, the HLG driver I listed is CC and CV which is why I thought I'd be ok in the scenario we've been conversing about. Due to the following: A: Such a small gap between the two voltages B: A driver that limits the amount of requested current. Would I be correct in saying, with this driver...

I understand now what's being said. With that..I'd wager to say the other strips would be heating up to and thus lowering voltage. With starting voltages being so close I don't see the samsungs being so hotter than the others that they get stuck in that loop and run away. But, I can see this...

What I'm confused about is there was a mention that the samsung strips could have a run away event leading to a fire. Voltage is electrical pressure, I get that. I also understand that the lower voltage 46 vs 48 like the other strips means its resistance is slightly less and as a result will...

As I'm finding out from members in the led forum ..if you use more strips and run soft you don't need heat sinks. Save that money for a driver.

281b+ with UV and IR for $14...

I was talking about current, the current would be limited by the potentiometer. Right?

Thank you! Like I stated my well water is void of pretty much everything other than sulfur I suppose. I say that because two different tds meters say the same thing...40ppm but it's coming out @ 4.9ph. Even after mixing in 1tsp of maxibloom it's only a 5. What's the best economical way to bring...

I bought them because they have UV and IR. They do work as I powered each one up individually on my small driver.

Does that take into account the driver has a brake via the potentiometer? I have 16 strips of 500-1500mA @48V of LM281B/301H strips I bought off of Aliexpress a year ago that I never used. I was going to buy all new ones if there's was something much better for a reasonable price but doesn't...

I'll just continue using my cheap timer if it's a off/on setting and nothing more. I heard dimming towards the end helped it ripen up..kinda like people start pulling light on time back at the end. Who knows..might be bro science. I nature though..they do get a sunset not a hard on/off and since...

I've got the 185h and it's been good ..but I'm going to get the B version as I got tired of adjusting the potentiometer with a screwdriver. What I'd hope to find one day in a affordable diy method is a way to adjust the io via a app. It would be nice to turn up or down power but also set on/off...

The driver I'm looking at seems to be CC and CV. https://www.meanwell-web.com/content/files/pdfs/productPdfs/MW/HLG-600H/HLG-600H-spec.pdf

Is this because the driver somehow senses and sets the voltage needed and it can't do that with two differentials on the circuit? I was hoping with one being 48V and the other 46V it would work. I'd be interested in the electrical reasons behind it. Thanks!

Can you run multiple strips,in parallel, that have slightly different forward voltage as long as it's in rage of the driver? For example I was wanting to order a few of those samsung strips above that @nxsov180db posted. The voltage is 46 and the ones I have are 48. As long as I run them in...

Jacks 321 with calnit? Anything else? I love maxibloom but also wanted to try jacks. I'm on well water now and doesn't have hardly any calnit in it.
