Did I say "in dialed in hydroponic system" or "depending on your setup"? You*re coming off as a bit of a fool if you can't differentiate between the two. My guesstimate would be, that less than half the people in these threads have automatic pH control, let alone EC...

Years later I have a possible answer: Hydro and DWC can, depending on the setup, produce higher PH and EC fluctuations. Strains that can deal with this better are more suited to DWC or hydro (without automatic PH correction).

I think that at 10" even the 25w are too much unless u're only dosing minutes at a time. I don't know that you'd loose "a LOT" by going higher, depends on the heatsinks of your strips, 20% isn't that relevant loss for UV b/c it's not on all the time. When u arrange several strips, you'd leave...

What's the wattage of those lamps? seems too close for the size. At that distance i reckon you'd want like 10 watts. If you have more short on pulses, you can mitigate too strong an intensity, but you'll wear out the bulb quicker. Or you just get two bulbs, mount them at 20", and loose like 20%...

I don't think there's a study for that. Some report that using UV in the last 2 weeks is enogh. Thinking in this thread is, ramp up from very low to what they can take during flower. No reduction.

Read pages 10 to 30 on this thread. Answer depends on continent u're on. Arcadia or Solarcure are the gist.

U're trying to give hillbillies brain dablage?

Well, this I would very much advise against. I thought we were past this after the last guy to suggest injecting bleach got some flack.

I suspect unit is using pre 2017 diodes. Efficiency wise it's likely not state of the art. LEDs don't age gracefully when compared with newer models, visible in their low resale value, I advise against it. Newer model from same maker should give better TCO. But yeah, that efficiency gain would...

Mathanol likely isn't an undesireable compound. Am consindering using as foliar spray,

Doesn't look that good efficiency wise using napkin math. Not that I can be sure since I can't find umol/j numbers on their site. Red flag if that data is missing, maybe i've overlooked it. Also can't see CRI, since u mentioned it's so good. Good cri gives you bad efficacy btw. At the end of...

What's different with the XLG drivers? Unusual to have adjustable voltage in such a low range? I think you'll want to power the sticks in parallel. feeding 24V to all strips and splitting the power. your numbers are otherwise correct, i didn't check your sticks. about 20W for 100 diodes would be...

I found this on the Nichia's. The light tools .zip has some data. the 80cri 3012K diode has 33,4lm at 65ma and 2,86V. At 0,186W we have 180lm/w. Would be about 7-10ish% worse than Samsung of same CCT and cri. But yeah, comparison depends on kelvin and cri of the product.

You are correct or course. Also the voltage needed, if whole strips were in series, would be a bit high. :D Point remains, we need accurate lm/w or umol/s for the Nichias at a certain current. And I'd still hazard the guess that the Nichia data I found corresponds to my Samsung data, the samsung...

Maybe not even that is true hard to find data on the Nichia, here's 2700k 80CRI comparison: Found Nichia at 189 lm/W without quoting amperage. Educated guess is 350ma. Samsung is 194,59 lm/W at 350ma. Fair to say they'd be indistinguishable IRL.

Probably none. Same efficiency. Apparently they have the best high cri 2700K by a slim margin. You'll find people valuing high cri, others dismissing it. I'm in the latter camp thinking that we're currently overestimating the influence of spectral quality because we just learned how to contol it...

I'm not here to give you a hard time, just to point out possible fallacies, use per your own discretion. Saying what she feels... Has she ever said anything that you took objection to? Has she ever mentioned anything that would challenge the views of anyone but the famed "deplorables"? This...

You're at least partially right. My opinion was solely based on the debates, I hadn't looked into the details of her career until just now. It reads too dense to be purely opportunistic. here you have my previous take on her. In the debates I found her needlessly demeaning towards others while...

I'd argue that my burden is lower, since both these gentlemen started attacking me. and i had two: How a politician who was in line with all the worst foreign policy mistakes is fit to be president, is beyond me. And something about the nature of societal contracts.

No rational argument, no linguistic wit -> unconcious feelings of impotence -> outward hostility
