No price point yet and as far as I know, not on sale yet Magnolia LED Grow Lights featuring Samsung LM301H and 660 nM LED Boards| Timber Grow Lights 700 watt, 3170k color temp, Samsung 301,s.....

Agreed....I believe that they are referring to the red spectrum and not the average of all of the lights. Seems that around 3.1 is close to the current ceiling.

Just checked them out. Good looking lights at a reasonable price. PerfectPar 650W LED - BoulderLamp, Inc.

I second that! Amazing service, quick turn around, numerous high quality freebies and no BS. It is highly unlikely that I will be buying from any foreign seedbank again. These guys made it so easy to do business with them.

I would say that the plants got fairly equal amounts of UV. The positioning was limited as the grow was done in RDWC and the plants were in a fixed location. Both plants were grown from seeds so I don't have clones of them and had not grown them previously. This was more about determining...

Yes, using the fluoro's. No, I haven't tried just UVA. I do think that I can run them for less time per day and delay the introduction to the plants. At this point I do need to change my approach. I guess the million dollar question is - Is UV use for indoor growing that much of a value add? I...

Okay, so the results are in from this experiment. Conclusion - At least for me, the results were mixed at best. The UV did not seem to make an appreciable difference in THC production and seemed to provide a slight enhancement to taste and smell. The overall yield did not seem to be impacted...

My fellow Timber users, here's a scientific based article about light spectrums and their impact on cannabis cultivation. It's a bit lengthy and technical. However, there is some good information in there. Some you may already know and some that you may have forgotten. Frontiers | An Update on...

"Trying to claim that those off the shelf bridgelux cobs mean anything more than PAR they produce is ridiculous." I never said that. I think that we both agree that their cobs are not as efficient as most strips. My point regarding their lights is that they are well made quality product that...

I'm not riled up.....though as I suspected you're just a cheap shot artist that thinks he's a wit I'm sure that you know all and grow the greatest bud in all the land Rumor has it that Juan Herrer and Jorge Cervantis reach out to you for advice on how to do things right Since subtlety and...

Fact is other lights grow just as good of weed. How do you know? Did you compare them? For less watts (and thus heat) and less $$$$. Oh and they have longer warranty (5 years) than Timber (3 years). Is this a fact because you say so? As I asked, have you grown with one? If not, your perspective...

Not to sound like a fanboy, Timbers are more than numbers. Midnight Sun do you own a Timber light? Have you ever tried one? After trying numerous LED grow lights since 2014. I can honestly say that Timbers are an outstanding choice. Just showing efficiency numbers does not tell the whole story...

You may want to take a look at the timber Fatty. It's an American made light with top bin diodes and multiple drivers. You can customize your light spectrum to mimic an HpS if you desire. I've owned HLG Rspec lights and prefer these. I prefer cobs to boards. I'm not knocking boards or HLG. I...

There's a lot discussion. However, 100% proof is elusive. Here's an older link that I found that doesn't seem to be product sponsored. http://medicalmarijuanagrowing.blogspot.com/2014/07/uva-uvb-lighting-to-kill-powdery-mildew.html?m=1 Overall, I'm going to continue with it. It has been...

Hey, thanks for the update. I'm going to be harvesting in the next couple of days. I'm hoping to have lab results in about 3-4 weeks. Regardless, using UV really upped the terpene and resin production. I'm going to do another run with them once the summer passes. Also, sorry to hear about...

I don't think that I ever indicated that I thought you were trying to sell me a light mate!! Don't get me wrong. I'm not rubbishing the other lights. All I'm saying is that if you want the best out of them, you need to add supplementary Far Red and blue/near-UV from <400-430nm. You will notice...

That's the trick getting the right LED grow light.... I'm all ears if you have a suggestion for me. I have used an HLG R Spec Scorpion https://horticulturelightinggroup.com/products/hlg-scorpion-rspec I'm willing to try something new.

No worries, it's all good. I appreciate the time and thought that you put into your responses. It is quite clear to me that you have a much more comprehensive understanding of this topic. I realize that you did not say bad. However, one could infer that UVB may not be the best way to go. As...
