Seriously - What's the best LED setup?

Do you just like hearing yourself talk? Most of your theories on light are ridiculous.

Saying purple doesn't exist because there isn't a purple diode out there is ridiculous. Of course it's made from blue and red. This whole thing came about when you gave a colored light a color temp. of which there isn't one. That was my entire case.

I've owned a few colored lights and have never seen a burnt out diodes, or output loss, and i could give a shit about fan noise. 1 of my lights doesn't have a fan.

The lumen scale isnt linear so it's not a good for measuring LEDs

What do you use? How do you grow? What do you usually yield per plant? Got any pictures? I'm very curious how all this sage advice has benefited you. You're so quick to shred others equipment with all the knowledge you keep telling us about. Show us

Again attacking rather than discussing the facts, now how about you answer some questions this time?

Which theories are ridicoulous, and why?

Then tell me the nanometer range of purple lightwaves?

Please, in short summary, tell me what I said about Lumen? Maybe just read the sentence again...
Lumen is the unit used to measure light intensity relative to the human eye.

How do you measure your light intensity?

What, where and how I grow doesn't matter, how does my lights compare if I'm a shit grower?
And compared to what? A completely different grow? Or just the 1000's of people out there who's somehow able to get clones from my plants and completely mimic every other aspect of my grows except the light?

Measuring of PPFD is the only way to tell apart light sources.

It's not like I'm hiding my journals...

You might not care about noisy fans, but you're not the only grower in the world and some people actually live or sleep right next to their grow.


Going from blurple to mid-power diodes got me:

About twice the PPFD at a slightly lower draw
Much less heat
Silence
Quality components


You're so quick to shred others equipment

Nobody likes to find out they've been scammed, but when the initial emotion sets, you should be happy someone pointed it out so you don't make the same mistake again.

If you truly take offense, you're a grow light manufacturer or seller pushing sub par tech!
 
I dont know anyone that doesnt want to talk about their grow. I tell you what. I won't reply to you feel free to reciprocate


You won't answer because you can't answer.


You're not discussing the subject anymore, you're just trying to keep directing questions at me that have no relevance to the subject.
I talk plenty about my grows in my journals, this discussion is about the science of light, not subjective experiences.

I don't take pleasure in exposing peoples' short comings but you're just too persistantly ignorant and unpleasant, so I'll take my time to expose your lack of knowledge and your attempt to murk science in your pityful pursuit of being right.

You're contradicting your own statements and you clearly don't know anything about light, and it's obvious from your posts in this thread.
So stop acting like a politician caught lying, and grow up and learn to admit you're wrong.


Im not trying to pick anything. The only colors that have a temperature are red, yellow, and blue. Purple does not. Please look it up.
Gun rack...There is a color purple just like there is any color. How we perceive this color is the definition of that color, No? Does this even apply to the conversation?

So purple is what? :rofl:
 
Haha that shut everyone up with that pic. This is a good read as I’m also interested in cobs or quantum boa it’s for firstly supplemental needs. Then full cycle in a diff tent down the road.
 
They are also a little short on UV-A and B, which are important for different reasons.

That's easy to deal with. Most any good pet store will sell "reptile bulbs." Tube type fluorescent bulbs from very short up to four feet in length, and I've also seen the CFL variety.

Make sure to turn them OFF before entering the grow room!
 
No, there are no ''purple'' lightwaves unless you mean violet/ultraviolet.
How the human brain perceives the light has nothing to with the actual wavelenghts emitted.
Look at any blurple light, there are no purple diodes, only red and blue mixed with some yellow/green/white/FR diodes.
Try to look for a purple diode, you'll find only UV diodes.

Isn't "white" light the same? Made up of a combination of other colors, I mean? If so, HtH do they produce it with a mono LED?

Yeah. I guess they are very hot, so you need to take care about the distance, and you really only need to run them for a little while, not a full day. Ive only read this. Ive never actually used one

The one I'm familiar with states that it's effective up to 20" away from the bulb - but that's for reptiles, lol, and I have no idea how that translates to cannabis plants.

I don't suppose that one needs to run them at all. But such things do seem to help with trichome production and/or cannabinoid content. The accuracy of that statement might vary from strain to strain, though (IDK). If so, I'd assume it'd be more effective with equatorial sativas and high altitude strains.

How people choose to run such things seems to vary from a few hours in the middle of the lights-on cycle during the flowering stage, all the way up to "whenever the lights are on, regardless." I don't know enough to make recommendations on that. I've run a small tube-type bulb throughout a vegetative-growth phase with no noticeable issues, though. But it was only 18 watts or so over nine square feet. Which is more than the number infers, since it's output is (more or less) in a specific portion of the spectrum. Still, it was only 18 watts. Don't fill your grow space with double-bulb four-foot fixtures, install reptile bulbs in all of them, and complain to me if your plants die and your cat gets cancer when it sneaks in to the grow room, lol.

BtW, I have read many times that the ReptiSun 10.0 is a good quality series of reptile bulbs. Avoid the 5.0 stuff (half the UV output, AfaIK), and I have never seen a 15.0 advertised, so those probably don't exist.

Cat cancer! Priceless!

I ran a 315watt CMH last season. with my regular lights. They are reknowned for high UV-B Its so strong that they have 2 bulbs, glass naturally blocks UV, and warn that they are very dangerous if the outside bulb breaks. I have to say i didnt see a huge increase in trichome production. Im doing it again with my present grow King Tut in RDWC to see if its kinda strain specific.One thing that i do know is that UV is usually generated by using Mercury. If your lamp breaks its a major issue.

That's a general thing with metal halide bulbs. The ones that aren't jacketed ("2 bulbs") aren't rated for use in open fixtures where there will be people present.

Unfortunately, I cannot quantify the output of the average metal halide or the ceramic metal halide version, so I don't know if that provides as much, more, or not as much as adding supplemental UV bulbs.

One thing that i do know is that UV is usually generated by using Mercury.

That reminds me, mercury vapor lamps produce quit a bit of UV radiation. But they're NOT recommended for trying to grow plants. I think I still have a small (1750watt, IIRC) one around here somewhere. It'll never end up in my grow space. Probably not outside for a security light, either, lol, and I cannot even seem to give it away. Good thing it was a freebie.

I used to work for Philips North America as a Manufacturing Engineer We build short arc DC Xenon and Xenon Mercury lamps. Take a look at this thing


If i shared these pictires already on this forum i apologize... i smoke pot.

So, thats a 10000watt lamp for a spot light


I dont know anything about metal halide, high pressure sodium or CMH to be honest. I was just asking if someone knew anything about CMH on my thread.

Were they doing anything with sulfur plasma lighting when you were there?
Wikipedia said:
The sulfur lamp (also sulphur lamp) is a highly efficient full-spectrum electrodeless lighting system whose light is generated by sulfur plasma that has been excited by microwave radiation. They are a particular type of plasma lamp, one of the most modern. The technology was developed in the early 1990s, but, although it appeared initially to be very promising, sulfur lighting was a commercial failure by the late 1990s. Since 2005, lamps are again being manufactured for commercial use.

Contain no mercury and are (pardon the pun) Hella bright, so bright that big buildings will run one and distribute the output via LONG light pipes. I haven't read anything here about the technology in seven or eight years.

Take a look at this thing

That thing appears to be professionally built, while still managing to look homemade, lol. What's with the threaded... rods(?)? Is the arc adjustable for some purpose? Regardless, it looks cool.

No we just made short arc Xenon, Mercury Xenon, and high UV lamps for lithography, and UV time trials.

I dont lnow anything about plasma lights. Sounds crazy.

Its funny you say that! It is entirely hand made. But, they are kind of a wonder of material science. They are made from quartz, Tungsten, Thoriated Tungsten, Tantalum, Molybdenum, Platinum, Xenon, Mercury and pure carbon. This one isnt finished.

The screwy looking things behind the anode and cathode are wires made from Tantalum. The inside of these lamps have to be completely clean on a molecular level. Any elements other than the assembly and Xenon gas will darken the lamp and shorten its life. Tantalum is whats called a "getter" as the lamp operates Tantalum will absorb trance elements left in the lamp. Theres no way to make it perfectly clean. I made machines and processes to help Production. A lot of my work had to do with cleaning the inside of the envelopes, the glass bulbs
