LED and BUD QUALITY
- Thread starter Tropical Sun
- Start date
LUX meters see the photons you are creating, LUX as we said is just some of the PAR range of photons
So it will see the total number of photons, i dont understand how this change something ?
Did this measurement change the initial count of the diodes ? of course not.
No matter how you flip it bro, you cant add intensity to a source that is limited to low intensity.
Not by adding another source which is exectly the same.
If you want to increase the lm\s of a source you must up his voltage.

higher lux equates higher lumen (given same distance and spread angle)

So plants do use energy from the source? Or the photons that fall on their leaves, as expressed by either PPFD or lux?
What does it matter if these are produced from either an areal of hundred tiny points or 1 bigger point?
It's irrelevant.
And misleading. No HID is a true point-source either. Most of a HIDs light is diffused by the reflector anyway...

LED light is more intense than sodium. The sodium may have a greater total, but it's the one spreading it out over a greater area.
From a different aspect, most of your HID light is reflected before hitting the plant. The plants not getting any sort of benefit that aligns with your point of view.
The LED lit plant, gets most light direct from these more concentrated light sources. You are batting for the wrong team pal.
This is close up of a surface mount LED. It's perhaps 5mm, though we can only see 3.5mm of it. The bit making the light is about 0.1mm2
Lets scale up. If that's was an LM301 it's likely to be driven at 0.4w to make maybe 80lm/w not 40lm/w. That's 8000 per cm2 of emission surface. An arc tube is maybe 10mm diameter? 25,000lm per cm. 17cm long? 425,000lm would come from a 600 if it had the same surface emission as a 301. Making the 301 3 times more intense.
Edit: damn it
I think he means led do produce photons slower than hid do.
You are not getting it, no matter how i explain it you still dont get it, i will draw a sketch maybe then you will understand.
It dosent matter if the photons are from 1 source or 1000 sources, thats not the issue, you can do both, as long as both of them as single light sources have high rate of light producing.
HID is only 50% diffused by reflector, but you are straying again from the subject, it dosent matter !
All that matter for the protection of the bud process is the intensity (rate) of the light being produced!
As long as this light is present in the same space like your bud, it will see this high intensity source, and will try to protect from it.
Again with your imagination... bro take a break pleaseLED light is more intense than sodium. The sodium may have a greater total, but it's the one spreading it out over a greater area.

you are talking about shit that dosent exist, only in theory.
Im with you on this subject, LED KICKS HID, ok we get it, i agree, But for now, not when this size unites will come out to market if any, for now, HID and CFL as single light source, out rate the LED.
I will sketch this for Cerathule so you can understand also.

But plants don't have eyes, they don't perceive light like we do. They grab all light particles via their leaves, which contain compounds that serve as photoreceptors.
Besides, if that would be true you should be able to cite proper scientific evidence that supports your claim.
Cannabinoids are mostly transparent to light. They rather protect from UV - which your HPS light contains 0.
Cannabis doesn’t produce resin only to protect itself from intense light, thou i’m sure part of the reason is to prevent
You can also make the plant produce more resin when you keep it badly root bound and cause more stress this way. ..you can see this in vegging plants when they are so badly root bound that they start to semi-bloom.
This is a badly root bound plant in veg. I made seeds with this plant in veg light cycle , i’m sure you can spot the seeded calyx:
Many compounds in cannabis actually have antibacterial,antiviral and antifungal properties = to protect the plant from these kinds of environmental factors. These types of compounds wouldn’t exist if resin would only be produced against light stress.
When insects bite holes into the plant’s tissue these “scars” will open a paths to pathogens and so the plant needs to protect itself against these by producing the various compounds that are in cannabis resin.
Part of the defense mechanism of sticky resin, i would think, is so that insects wouldn’t want land on the buds. ..but that’s just me speculating.
Some plants give me skin irritation when my arm brushes a blooming plant, some more than others, and insects/animals could also feel it when they brush against a cannabis plant.

No one really knows why the plant does it, just can speculate. No scientist will say they know exactly why.Cannabis doesn’t produce resin only to protect itself from intense light, thou i’m sure part of the reason is to prevent dehydration caused by sunlight, heat but also wind.

How the trichomes grow is mostly genetics.
Dont need science to tell me what my exp and eyes can see bro, also science is with me, you cannot add intensity (rate) unless you up the source, wont help you putting many sources as you want if they are rated the same, thats science, no need no one to validate that, known for many many years.
It dosent matter if the plant has eyes or not, trichomes are a defensive measure against HIL, high intensity light, you cannot argue that, so please take a rest.
Your UV claim dosent hold against 50+ years of poor NO UV HPS growing killer bud, sorry, you are wrong, reality is not supporting those claims, maybe it will make it better to a degree, but its not the whole story.
The other debate, about what is the rate threshold you might ask, i think its 2000 at least at source.
You can add anything you might think to this logic, its from my own research, you wont find articles about it, just growers exp over the years.

Sorry, i dont have bugs in my indoor, also you dont, and you still get killer buds.
Bugs are not the reason for this defensive reaction, not from what reality shows, only exist in "scientific papers"
If it was the reason, the whole study of HIL and UV would be useless, Indoor growing without bugs would be useless, clearly this is not the issue.
If you are busy speculating, at least have some foot hold of reality before.
i have 1 plant outside, 1 month old, it is bitten from every angle and guess what... no resin, no flowering.

So you ignore proper evidence that cannabinoids largely absorb UVB yet claim science is with you? I think you are the only one believing that.
You haven't even read the study in such a short time. You ignore everything that is being brought forth but build your own reality using your fantasy ideas. This is mental.

Some call that urban legends

it's perfectly fine, this what Prof. Bugbee said, they've been looking into it, but they can't figure it out properly. There seems to be an interwoven causality at large, and yes, why not? Photoreceptors can cause a gene response similar to an immune response or stress from other sources, like salt or drought. So either method could work, and has been shown to work, but not in all cases reproduceably.
