Back to the topic of lighting spectrum and intensity effects on quality… Many people have cited Dr. Bruce Bugbee & Mitch Westmoreland talking about the effects of light spectrum on secondary metabolites, or the lack there of… I just watched the Bugbee/Migro podcast from earlier this year where...

Sorry to see you get discouraged egregory. This forum can certainly get off track and can also be a mean place sometimes. That said, some of the most insightful envelope-pushing threads I’ve seen here were riddled with trolls, name calling, and bullying. Those were the good ol’ days...

I’m not sure we were both saying the same thing, but it gave me the chance to illustrate my thought and it sounds like you have seen the effect in action. That’s all I was getting at, was that with more quantity of individual point sources (chips), depending on spacing, power, etc. you would...

No, I wouldn’t believe the opposite. Here is a quick little blurb from Google AI that is worded quite nicely regarding how the inverse square law works in regards to multiple light sources. “When multiple light sources overlap, the inverse square law applies to each individual source, meaning...

This is why strategic defoliation is important as well. You could always add some side/inter-canopy lighting if you were concerned with lower bud yield. But really, training the plants for more tops early on is your best bet, regardless of your light fixture. I would guess fixtures with higher...

Geekbeast Pro Lumatek 3.1 zeus

The only potential downside I could see to the geekbeast is there seems to be potentially large spike of UV that the spectrum graph doesn’t fully illustrate and a higher percentage of blue light relative to the lumatek. I would be concerned about how much UV exposure the plants were receiving.

House & Garden products are “absolutely crucial” additives for growing the finest weed, lol?? It’s Potassium Phosphate and Sodium Sulfate. Typical pk booster with added sodium. Why would anyone want to add sodium to their plants the last 3 weeks of flower? Why not use potassium sulfate and...

I use a central reservoir (25 gal insulated cooler), a water chiller, and 2 radiators for my climate control. This allows me to keep my 4’ x 8’ tent sealed, closed loop and I can supplement with CO2 without it just dissipating into outside air. Costs more than a split unit, but is more...

I’ve seen you mention this a few times, but would you happen to have a site or source for this information, even personal anecdotal experience? From what I’ve read, green light still plays a role in secondary metabolite synthesis albeit less than red and blue wavelengths. While I personally...

I get condensation on uninsulated lines with 56F water flowing in a room with 75F ambient air temps, and that’s outside of my grow. If it was inside my warm humid grow room it would condensate like a fire sprinkler. I’m not sayin that you would water cool your lights with that cool of a water...

It’s a cool idea, but I would be worried about condensation accumulating on your cooling pipes/heat sinks in your grow room. I’m guessing you would exchange the heat outside of the grow area, but the heat sinking taking place inside the grow would likely get drippy with condensation, without...

I ramp them up to full power gradually during veg so they are at full power day 1 of flower. And my environment setup is pretty dialed. My tent is only 6’ tall so I keep the lights at full height and let the plants grow up towards them.

I run 2 of them in a 4’x 8’ tent. They put in work!

Thank you very much! I did check out that link to the previous testing that I believe LED Teknik put out some years back. The older data sheets even had the spd for the regular vestas if I remember correctly. That along with the CCT vs Current chart were what helped me guestimate the color temp...

Hey Growers and light enthusiasts, I just wanted to share a little DIY project I’m currently working on for a small veg/mother space. I’ve always been curious if plants would respond differently to changing spectrums and intensity throughout the day, and I’ve built a fixture to try to find out...

I’ve had a few meanwell drivers quit on me within 3-5 years. HLG-120H-C1400B & HLG-320H-C1050B. About a 20% failure rate with those drivers in that timespan from my personal experience with them.

Damn, I ordered Gen 2 strips about 4 weeks ago because Gen 3s were only available in bulk with a 6 week lead time. I got them from digikey too
