Curious why you believe we can't have autos and keep photos?

I never buy veg-only boards, but that's just because I have an OCD thing about thinking I just MIGHT need to flower with them someday... But yeah, go for the 288s, man. They're a steal. Personally, I wouldn't take the chance on the drivers.

If only those SF fixtures used drivers with accessible dimmers... I believe they're considering addressing that fault in future designs though, as they commented something to that effect on Migro's test of one of their fixtures.

Yeah, I never would have tried hempy if not for MC. After the simplicity of ROLS (just add water, and maybe a top-dress at flip), there was no way in hell I was going to switch to a multi-part nute regimen. Don't know how peeps put up with the hassle of full hydro, with pumps and lines and...

My wife has a couple going right now, actually!

Finished my first hempy run a couple of weeks ago, and I'm sold. I did a 75/25 perlite/vermiculite mix, with about 1.5 gallons of medium in a 2 gallon bucket (after everything settled), using straight Megacrop, with no additives. Pulled 7.5 oz from one HSO Blue Dream plant that was half-dead...

Cold temps in the grow are Satan himself. @Moflow has clearly made a deal with the devil.

Even if you can't rely on the lux meter for precise readings, I think they're still a good thing to have around, as they can - at the least - help you dial in uniformity of light across your canopy. But then the lux app ought to do the same.

In those talks does he explain how he came to discover this?

The diodes in the HLG boards are more efficient, and therefore produce more actual light per watt. It's cheaper than the Mars, as well as being higher quality. I'm no Mars hater, and for anyone who has one of their newer white fixtures, I'm sure they're absolutely fine. But between those two, I...

Lux meter (cheap on Amazon or eBay) or even a lux app for your phone (not super accurate, but definitely better than nothing). As for the dimming - I just figure it's saved energy. Granted, it's a minimal amount, but savings are savings. Additionally, lower wattage means less heat, which should...

First of all, I love the cab, man! I have a soft spot for them, as I started in one. Still use it for the nursery and a couple of overflow spaces (3 chambers). What are the dimensions of your space? You mention a mom, so I assume you have a separate veg space? What's that like? I usually give...

You must be new around here!

I'm 3D printer-ignorant myself, but I do have a lingering interest. One of these days. But that's approaching rosin press money, and that's a bit of kit I would REALLY like to have...

Yeah, no doubt, bro. I'm sure I'll end up using UV and other colored monos at some point, just out of pure curiosity, but based on what we know now, the game is appropriate intensity and yield. Besides, I'm really damn pleased with the aroma, flavor, and potency of everything I've grown under...

Yeah, I kind of had a feeling all that hype they were trying to build would fall flat. I'm still a bit intrigued by their choice to pump that 660nm so hard though. And this is a great example of what we've been discussing in the other threads these past couple of days. Another manufacturer...

Oh, and as some are a bit dubious about Bugbee's tests, due to his position with Apogee, it should at least be noted that the study you linked was funded by Valoya, who - if I understand the paper correctly - also happen to manufacture the fixture that is claimed to have produced the highest THC.

Thanks for the link! Somehow missed it the first time. It's an interesting study, and a beginning perhaps, but... It certainly doesn't prove the point. We need far, far more than two tests, first of all. Secondly, I'd like to see the LED test done with a light that has the same amount of UV, but...

Interesting spectrum. Quite the peak around 660nm.

In other videos he speaks on the spectrum of HID, and voices the same conclusion - the color isn't a big deal (yet). I'd love to see the info on any test that shows 400nm-430nm "has been shown to increase cannabinoid and terpene production." (And that's a serious statement, not sarcasm.) So...
