You're dead wrong, as I stated, I did it earlier yesterday. You can't solder to PENCIL graphite because of other present impurities. You can solder to pure graphite. How do you think older linear variable resistors (like those used in 80s analog synthesizers) got made?
My god, quit relying upon inaccurate wikipedia for fuck's sake. They can't even keep current with LED technology. The carbon, hydrogen, oxygen in "silicone" are used as solvents (hydrocarboxy) and the rest is ground sand.
"How do you connect components like resistors? You can't solder them. "
Uh, yea, you sure as fuck can solder to graphite ink traces. I did it today. Flux is a magical thing. Perhaps you should get your IPC J-STD-001 certification before talking nonsense.

" Pollenated weed plants grow seeds instead of synthesizing THC and other cannabinoids. Well, they still synthesize these compounds, but in much smaller quantities."
As a medical user that grows it all the time, WRONG.
Most of the useful cannabinoids are produced and contained within the trichome. Seeded sections of flowers tend to have higher concentrations of these trichomes, as it's a protective measure against UV damage by the sun to the developing embryo, due to how thin the tissue of the calyx is.
Exactly. I've got a 55 gallon freshwater, using a single 50w 6500K panel (I'm only driving it at half power.) Everything is well-lit and the plants grow so quickly I'm having to remove an entire jungle every time I'm changing the water.
And anyone with half a brain knows they can just go to the manufacturer direct in most cases and get what they need. They have no qualms selling to you at the price they give to wholesalers and retailers. None.
On the other hand, finding someone that knows EXACTLY what you need (my job) per a given situation is not easy, which means most people are still stuck listening to the marketing of fly-by-night ebay companies and less than reputable LED grow light companies that claim to have patents when they're just reselling stuff from China.
"This Wikipedia page [wikipedia.org] has several examples of the efficiency of different kinds of lights. Most of the LED examples they give show around 50-100 lumens per watt."
Quit relying upon Wikipedia. It's outdated. Cree's already pushing 300+ in the labs and have 200+ commercially available. Most LEDs are pushing 130-150 right now.
You've listened to wayyyyy too much marketing and read too much ill-educated nonsense on cannabis forums.
The light cycle itself triggers flowering. Red light just happens to be a bit more efficient than blue for photosynthesis. I've done flowering under pure blue light and still obtained the typical stated yield from the seed supplier's website.
HPS gets used for flowering because the intense green output, which can go through the canopy, down to lower sections of the plant, where the green has overall superior quantum yield, as red and blue will not penetrate that far. IR has minor effect.
Guess what? We've got white LEDs pushing well past anything HPS lamps can do in terms of lumens per watt (really we're looking for photon flux density) and at color temperatures much closer to the natural light of the sun. HID? Finished.
"Marijuana plants like direct, intense sunlight. Unfortunately LEDs aren't very scalable. As you increase the current they start to run into physical limitations and the efficiency goes to hell. A 100W led may only put out 50lm/W, where a 1W led could put out 100lm/W."
I'm sorry, we've got plenty of LED systems out there pushing 2,000+ umol from several feet away, like any HID. And typical 100w LEDs are about 130 lumens per watt. Cree has LEDs available for the consumer that at 1w drive get 200+ lumens per watt (Cree MK-R) We figured out the Auger/watercooler effect and are working around it. We've got LEDs that dump 150+ lumens per watt at 5-10A drive current, now (Cree XPG2.)
"HIDs are actually extremely efficient (Around 100lm/W) and scalable (bulbs go up to 1kw+)."
We've got 1,000w LED packages in 70mm x 70mm size, with better efficiency.
" To get and equivalent amount of light out of LEDs with some sense of efficiency, you'd need thousands of them."
Plants care about photon flux, not lumens, which is weighted at green wavelengths for human vision. That's not saying that green light isn't useful in itself, but lumens mean jack shit when it's overall photon flux density making the real difference. I'm questioning how out of date your information is. Seems like way early 2000.
Uhhhhhh..... what? Speaking as a medical cannabis user and grower, and as a landrace genetics preservation specialist for a Dutch seed bank, you're totally, absolutely, utterly wrong.
Let's take one of the crops I've done. Wheat fodder grass for animals. Using current traditional soil methods, one acre of fodder grass will require 100,000 gallons of water. Most of this water is lost via transpiration of the plant and evaporation from the soil.
I can build you a 1/8 acre building, load it up with recirculating vertical-stacked NFT channels, and you could produce that same acre of grass using 1,000 gallons of water.
"And she's been unwilling to loan me a unit for test purposes, dammit;) "
Your sister does my exact job.
What sort of unit are you looking for? I've got tons. General purpose, microgreens, hell I've got technology to grow some plants without any light at all (very useful for the cattle/sheep ranchers) with a 99% reduction in water requirements.
"LEDs aren't there yet. You can't get cannabis to flower properly under LED lighting, nor can you get the sort of growth rates you'll get under HID lights"
Yea, explain why I made it on High Times Pix of the Crop six years in a row using pure LED lighting.

Depends on the type of silicone. I see you're only smart enough to be able to think of one type of silicone. Sad.

I can get first-quality custom METAL PCB for $0.50 per square inch from other companies. Your sourcing is either rusty or you're shilling.

And I quit paying attention to you right there. Just about anything with silver in it will have higher electrical conductivity than iron or steel.
"How do you connect components like resistors? You can't solder them. "
Uh, yea, you sure as fuck can solder to graphite ink traces. I did it today. Flux is a magical thing. Perhaps you should get your IPC J-STD-001 certification before talking nonsense.
"No, it didn't. That's SILICONE not silicon."
What in the hell do you think silicone is made from?
Hint: There's a reason silicone lubes rip many rubberized sex toys apart, and it's not the suspension solvent of cyclopentasiloxane.

The only answer to antitrust is simple - break those companies apart and KEEP THEM APART.

"Sapphire is hard... 9 on the Mohs scale, and the only substance harder is natural and synthetic diamond"
Not even close. Boron is harder. Tungsten is harder with a Vicker's maximum of 2400, Sapphire 2300. Sapphires won't scratch my pure tungsten ring.
"and the only substance harder is natural and synthetic diamond. I find it difficult to believe..."
Well, given your lacking education on material hardness, not a surprise you can't believe.
Density is 100% genetic. Sativas will produce fluffy buds no matter how much light you throw at them.

Try a couple hundred, easily fit on a 30mm x 30mm COB array board. Those are 5W LEDs each. The Cree MK-R is a 15W LED. 100 of those is 1.5kW.
