I don't know if "selling" is the right word. Endeavoring to sell, perhaps. Do LEDs make one stupid and susceptible to Infowars level news? Or is it a by-product for growing loose, undeveloped buds and having to convince yourself that they are good?
Sock puppets, sock puppets everywhere...

It's an issue of intensity, not of brightness.
Where did you learn that?
What's the difference between brightness and intensity?

BTW: it's not brightness or intensity. Brightness is not an SI unit so that's ambiguous. It's about irradiance or more specifically PPFD (e.g. µmols/m²/s) or how many photons reach the leaves of the plant.

It not about HPS vs. LED. It about growers not understanding LEDs. they replace their HPS with some shitty Chinese fixture where the seller lies about how it's irradiance is equivalent to the flux of some HPS lamp. Which is total bullshit but no one seems to understand watts and irradiance.

More likely the difference will be found in terpenes/terpenoids, phenylpropanoids, and fatty-acid- derived volatile molecules. Combinations of the various wavebands in the incident light mixture effect plant growth, development, metabolism, and morphology. (Folta K., Carvalho S. (2015). Photoreceptors and control of horticultural plant traits. HortScience)


But seriously, where did you learn: It's an issue of intensity, not of brightness
Citations are always a nice thing to back up what you say.

A bulb and the sun can have the same brightness, do they have the same intensity?

Not selling anything.



You must be one of those that thinks photons from an HPS are superior to other sources of light? How could that be? Does HPS make faster more powerful photons?
You must be one of those people who think bad bud is the same as good bud. Let's get together. If your LED bud is good it will be the first I have ever encountered.

How many standard sized pillowcases does about a pound of your weed need to fit it all in?

Brightness is not an optical measurement. But no I do not believe a light bulb and the sun can have the same "brightness". If I stare into the sun for a long time I will damage my eyes. If I stare at a light bulb it cannot damage my eyes.

But yes they can have the same intensity at different radians (i.e. apex angle) in the solid angle. Look at a calculator to convert candela (intensity) to lumens (luminous flux) . It all in the angle.

What is this thread about? Violating privacy?

Lol. Eight then. That'll fly off those dispensary shelves. Especially if there is a fan on within 20 feet.
WTF??? That's funny? Why not go buy yourself a sense of humor?

You too.

I think one can be smart, directed, and focused, without being obnoxious. Not sure I can say the same about you.

“Brightness is not an optical measurement”
What is it?
Whatever you want it to be. I call it ambiguous. The International System of Units doesn't call it anything.

Oxfrod Dictionary says:
the quality or state of giving out or reflecting light
the quality of being intelligent and quick-witted the likes of which is difficult to find on rollitup.

Are you a proponent of the “Oxfrod” theory or are you speculating on the IQ of rollitup posters?
