my phone maxed out at 17k so I bought an epsilon. Tried to use it to dial in the new led. I'm good now. Just bought another 100w hlg 4k to go with the 3k. Good mix.I just use the free app... better than a lot of those cheap ones and like I say I use it to ballpark.
Not true... not even close.the thing is once minimum spectral requirements it's all about the intensity . sort of like vitamins . you dont get bigger on proportion to the more you take. they meet the minimum requirements and then the rest are expelled. 2 lights the same out out both with different spectrums as long as they each have the minimum amount thr rest is about volume. doubling the par rating will do very little more . it is the same with the sun . it has a particular spectrum in the spring and summer but growth is similar. even the footcandles . there is 15000 + or 150000 lux on a bright day but we don't have plants significantly bigger than normal. size is also extremely relevant.things just dont double. they move in percentages relating to plant size . +/- 1 or 2% at a time . those crazy adds that say DOUBLE your harvest or EXPLOSIVE growth rate all fake terms that are meant to appeal to inexperienced customers. if a product adds more than 5% to your yield it means your were not doing some thing else in the first place
post itNot true... not even close.
You cant use vitamins we are talking about spectrum... and yes more of any has thier effects... to match your analysis the more steriods the bigger the gains... see analogies are used support to an argument thats not able to be made.
Proven facts UV increase cannabinoid concentration and may other implications. The info you are using has been far disproven now and is outdated.
I didpost it
Nothing i don't already know... old and outdated infonow here is another very specific
It has been noted that there is considerable misunderstanding over the effect of light quality on plant growth. Many manufacturers claim significantly increased plant growth due to light quality (high YPF). The YPF curve indicates that orange and red photons between 600 and 630 nm can result in 20 to 30% more photosynthesis than blue or cyan photons between 400 and 540 nm. [8][9] But the YPF curve was developed from short-term measurements made on single leaves in low light. More recent longer-term studies with whole plants in higher light indicate that light quality may have a smaller effect on plant growth rate than light quantity. Blue light, while not delivering as many photons per joule, encourages leaf growth and affects other outcomes.[8][10]
Wikipedia is not even allowed in schools for a reason... im talking actual scientific studiesthis is the article .
This sounds like the same shit they were talking about in 1970's. Grow lux vs HID.now here is another very specific

and after reading 4he article it says just that ...IT MAY have an increase but that has not be shown conclusively and not by a great amount .In just going to link this.... again. There are plenty of links and references to actual scientific studies. Much like we know plants use photons outside of PAR. Green light is used in photosynthesis etc. All these claims are debunked and old.

so they fake the documents to fight light power? lolWikipedia is not even allowed in schools for a reason... im talking actual scientific studies
the point is that better light spectrum does not mean better growth .
