The penetration is a lot different when the lights are designed to be spotlights rather than floodlights. One of the major complaints with old LED designs is the lack of penetrative power, which the cob design has largely improved upon. It's only obvious as to their industrial uses, which are...

Very high output yes but the coverage is less than desired. That's why I went with the 2-cob Vero 29s so I'll be able to adjust the coverage to suit my needs. How big is your space? The 500W model is only good for a 3x2.5' space in flower - that's what others have already mentioned before.

I guess so, I don't want to rip the adhesives off but I think the specs are still the same. I'm guessing it's an LPF-90-42 instead of the NPF-90-42. Where are the NPFs made?

Hmmm that slipped past me. What's the difference between the NPF and LPF?

If you want the full 8MP shot I can send it to you for your perusal. I would've waited for the other lights but I've got a schedule to keep lol. Warranty for the Optic Veros are 5 YEARS, I doubt I'll still be running the same lights after that long (or they'd be used for another purpose) since...

Thank weedemart, I'm running coco so I'm not really worried about gunking up a res. I'll probably try a stronger concentration in a few of my plants and see how they react. Maybe use it as a foliar and see how the plants react to a little stronger formula.

Here's their latest 200W model, purchased after they went "dark" for a time a few months earlier. The case does get a little too hot for my taste, I'm thinking of either getting small fans to blow across the lights or install 40mm fans on the exhaust ports to facilitate air movement. Back...

So basically no one has tried it in concentrations greater than the recommended? What's the worst that could happen? Plants dying?

I know, but I don't want to spend any more on MORE nutes. I'm keeping it simple, just use what I have on hand. And since I have A LOT of FLP (and I do mean A LOT no kidding) I was planning on using it to boost N a bit but have no idea if the increased humics will have a negative effect (I think...

Is G&H synonymous to General Hydroponics? I'm also considering the FLP as a weak Nitrogen booster, how does it work out at strengths over the recommended (1mL/Gal)?

Go for it man. Why don't you license your design to other DIYers in other countries so they can sell it locally? Would be a great way to get the LED grow revolution going around the globe. Save all the poor folks who are using inferior quality lights. As for your tip - were there any major...

That's pretty slick Pos, looks to be more polished and well-thought out of compared to other commercial products (think Chinese with "Pro" labels). Maybe you need some better marketing and "loud" customers lol. I would've gotten soft-driven 3590s over the Vero29s but I just got what's the most...

Now you're talking. Time to put a name on those lights.

Budget? I myself had my eyes on A51 lights but ran into the same problem as you. GoGreenLEDs also didn't want to ship internationally, and Pacific Light Concepts didn't look like they were selling at the time. JimmyIndica's lights are badass, I would've gotten those if I had the opportunity but...

Wow Supra, this is really good stuff. Can the spent soil be reamended more than once or do you have any recommendations on the number of uses? Bud that can be smoked without curing (also saving time) - really interesting point there. Almost all of the books and resources I've come across highly...

Cobs are just basically better clustered LEDs, not dissimilar to the LED modules used in 1/3/5W generic or cheap grow lights, just packaged differently and performs much better. You know, technology actually designed to do what it's supposed to. It's the same with bulbs - you're not going back...

I think I'd trust cob LEDs over clustered LEDs easily. Streetlights and industrial flood lamps are the few applications of cobs, without a doubt I'd buy that over LEDs used for flashlights.

Hey free is free. Go and use it! Other users might be able to chime in on this one.

I'm not sure what gauge that is, but most will recommend an 18awg solid wire for LED light use.

If that ain't my brand I ain't touching it No I'm not promoting the product.
